AW55-51SN / RE5F22A Transmission Teardown Inspection - Transmission Repair 

Dude .... you are absolutely amazing with your gift of not only disassembling the unit but the way you express and explain what you are doing . You should definitely be praised for what you do . God bless your determination and drive in making all of us understand and handle our fix. Please keep doing what you do to help us. Great job.

Great video thank you! I have a 2003 XC90 with 180k miles and the diagnostic software tells me I have a problem with the SLT and no.5 solenoid. I was toying with the idea of getting it fixed but I realise now how much work and cost is potentially involved and with the age and mileage you've helped me decide it's not worth it. Really educational video. I love watching people who know what they're doing!!

A pleasure watching someone perform his job with ease. When you know, you know. Subscribed!

You are the "homme"! I have a local guy trying to sell a great looking V70 for cheap but I now know I will not try and attempt to buy and fix it being this trans is way beyond my patience threshold and wallet to try an fix for a weekend project. You do great things here Sir and we can't thank you enough! Keep em coming!!

Very interesting video. Old but still relevant in 2024. Thanks.

I'll have to watch this 5 more times before I try this!!! on my 2001 V70 XC !

Great video Hiram! You work so much faster than I do!

Excellent video! This helped me understand what might be wrong with my aw55-50sn, thanks from the uk!

You are excellent at what you do.. I can appreciate your ability and your knowledge ..

Fantastic teardown, information and over info provided. The biggest thing taken away is doing your routine maintenance ini regard to fluid change saves thousands of dollars like always on these Nissan transmissions. Use Nissan Matic or Amsoil at manufacturer recommended intervals or sooner to be on the safe side.

you sir are a smart man i just finished auto trans class at tech school and iam still blown away by them wrench on my friend!

Thanks for the Acute Elaboration & Distinction Hiram about Misdiagnosing the Valve Body on this transmission!

Your a beast at rebuilding front wheel drives !!! I will stay with motors only.

hi Hiram, thanks for passing so much info. i appreciate your video big-times. thanks again.

Great video. Learning a lot about this transmission (it is in my 2002 Volvo S40).

Thank you sir. Your videos are great. I appreciate you taking the time to do these videos for us. Please keep it up.

Excellent work Sir. Thank you for sharing. Charles from Mesa, AZ ♥

Awesome vid, i love watching stuff like this

you the man when it comes to this, I have a 04 Nissan maxima se, and when I put it on reverse, it hits hard, and I don't want to drive it. I was hoping that looking at your videos I can fix it myself cause I don't have the money to send it to get fix. but thanks for your videos its cool...

Amazing skills man!! I dont think id ever be able to put one of these back together

ATSG has a technical manual for this unit that covers all vehicle makes. It is staggering... I've read a lot of service manuals and know a lot about working on cars. This manual is something you really need to go to school to understand. That being said, I'm still going to rebuild when the time comes, and fortunately I have a lot of time to learn before I have to do it.

Amazing video...can not find asembly video...i realy miss that...thanks for showing the automatic knowlegde

Wow it is amazing to watch a Master of his craft. Thank you.

Muy bien tus videos Sr Hiram.ótimo trabalho.Deus el Bendice

Hiram thanks for the information it is great. I appreciate your experience.

This guy is transmission genius...

Thanks for the video u r truly good at what u do

Another great video! Thank you!

Keep up the good work!

Very good the classes really enjoyed

Hiram is THE MAESTRO! Just rebuilt a AX4N tried to find a HG video on this one and disappointed to find none

Awesome video. Would be great with a video showing rebuild with overhaul kit for the AW55-51SN as well!

Hiram very nice video man Grats

You are amazing !!! Thanks

@6:32 I think Sonnax has these special metal retainers out now that you can put on the electrical connectors for the linear solenoids in case they get broken trying to disconnect them so you can still use them.

He makes it look sooooo easy. I would like to see him put it back together again. I bet it is a lot trickier.

Exelente Gutierrez, desde venezuela reciba un cordial saludo y que sigas cosechando exitos.

I wanna break my trans just so I can pay you to fix it! Great job !!!

the scary tihing is your knowlege and skill makes it look too easy :D

Great job Hiram I'm a first time visitor

Thank you very much for sharing your knowledge. I have a question here: Is there any difference between this unit AW55-51SN and the unit AW55-51? Thanks in advance.

It was a very informative video great job you make it look easy but I know its not. thumbs up.

Blown away with the complexity of the AW transmission and especially your expertiese, a privillage to watch. I am about to renew the fluid (Gibbons) on my 2005 V70 112,000mls for the first time, runs fine at the moment. I somehow wish I had not watched this, especially at the "high mileage is about 100,000mls" comment 🙄 Get as much of the fine floating metal particles out as possible.

I fixed the problem with my Volvo transmission with a rare earth magnet. I simply placed the magnet on the valve body pan. After driving for a few days it shifted perfectly

absolutely superb!

MUCHAS GRACIAS!!!! SUPER VIDEO !!!!;

and to think... he's gonna put this thing back together. Great video - but now, I'm scared.

one of thebest viedos

Wow.. ur awesome! My 06 maxima just started to act up, I babied it home and that's where will it will sit until I find someone like you! Thank god for having a second car, so once its rebuilt I should be good ? No need to trade it off ? Only 69,000 miles now.. just changed fluid 1,000 miles ago , go figure.. Thanks much!

Good video I like it and is very helpfully.Thank you

He did very good job he explain every parts take them out which part bad

Intelligente hermano gracias x Los videos

THANK YOU BROTHER THAT HELPS ALOT ;)

Can't believe this little thing puts down that power.. I have an 05 Volvo s60R, 230k, well maintained. Original trans shifts decent, not real problems. I've got this converter slip of about 500 rpm or so in 3rd sometimes. I know they do have the slip built in but this seems double. It will hold rpm then increase speed by near 20 mph before converter locks back up like a cvt feel for a few seconds. As i add more power it seems to be more pronounced. So before adding more power I'm doing a transgo shift kit to make everything better, I hope.. I need to get vida going again to run the adaptation. Hopefully this will improve some of the shift characteristics

thank you

Thank you

Спасибо!!! (Thank you)

Love this guy! this is weird to ask here but im loosing my mind! I have Renault with same transmission. Issue it has is that i loose D after tranny warms a bit. If its cold it Works like charm. Sometimes it does that when i put on N or R it goes to D. I took valvebody out and got new one in (i made sure solenoids had same adjustment as in old one) new oil in it and correct level but sitll no go. I know this is long shot that guru c this msg but i have no clue what to do…

Thanks this helps a lot. Can one connect 12V to the solenoids to test them?

Another great transmission video. Have not had the chance to do this unit yet, but now looking forward to it. Question: What method do you use to remove the small bushings out of the planets and the direct shaft? Looks like using a punch would be tough. Thanks!

Thanks for all the videos, perfect and very helpful. I wanted to ask you or anyone here, in the minute 10, exactly, you (Hiram) said "get this thing out of the way..." and hit a plastic behind the valve body, can you (or someone) tell what is the "thing"? Is it very important to put it back? Thanks. I'm working on a AW55-51N for a Volvo C70 2007.

Thank you sir Forklift what tipe transmission come

Hi Hiram! Thanks for sharing your videos, I am overhauling this specific trans and have run into an issue hopefully you can help with.. the direct clutch and 1-2 reverse clutches use a "cushion' spring in the pack along with the steels and frictions..my manual is not clear on which way the cushion spring goes in, do you know by chance? Thank you for your time sir!

Thank you very much for this fantastic. Could you explain what is happen in this gearbox if I shift into Neutral? Thank you

Muy bien vídeo Señor Gutiérrez. Una pregunta tengo un Nissan Altima del 2006 creo que con esa misma transmisión, le cambien el motor pero ahora no tengo reversa, todo funciona bien pero no reversa. Alguna sugerencia.

Great video. I was wondering if a shift solenoid would cause my gear shift icon on the dashboard to show " - " instead of the actual position of the gear selector? Thanks

You are awesome. I watched your 4l60e video twice and then rebuilt mine in my truck. Works like brand new. Question on this one is this the same that is in an 05 Altima? Thanks again

Hi, thanks for your video. I replaced my linear solenoids (I know you don't recommend that) and need to calibrate them. I'd like to take the valve cover off and drill 3 holes where the solenoids are so I don't have to keep taking the cover off every time I adjust the solenoids, but need to figure out a way of plugging them. Do you know of a plug and grommet kit or anything I could use to plug the holes? Thank you.

Very good video, You have a new subscriber. Thanks Hiram. I have not yet looked through your other videos. Could you do a breakdown of the common saturn sl1 say 95-99. Its a cheap high mpg vehicle and im thinking about buying one. Thanks again.

Good day sir,,, thank you for your wonderful vedio.. im hoping if you can help me on the right direction of the low reverse sprag?? Thank you in advance

Hiram, I hope you are still posting these great videos. On the last clip I watched (about the THC 350) You mentioned that you were concerned that not enough people were subscribing. There may be a reason. MANY people are now watching Utube clips on the new model "smart" TVs. These show ONLY the video with no surrounding text or controls, so it is impossible to subscribe/like etc from the TV. Encourage people or hang up a text sign in the background, to log on via a PC so they can subscribe. ALSO use ads in your clips, you will get rich from the ad revenue.

Hi Hiram, Excellent video and I am very happy that you have extra talent in explaining very useful things through your experience with those trans. I have 2001 volvo s40 and same trans crashed and no signs of connectivity with the engine. I am going to remove and inspection. Before I watched your video. Thanks for your time. Do you have any clue about my problem ?

Very details video great work. Would you by any chance have this same detail but with an RE4F04A jatco?

Good video. Nice

Hi Hiram Gutierrez, Great Video, Thanks for doing this. I got a AW55-51SN no Fwd or Reverse whatsoever no codes , Fluid level is ok. Fluid smells burnt it is not black but dark brown . I checked all the sol they all measure good and respond electrically apart from S4 , S4 measures good but when I trickle it with 12 volts doesn't make any sound. Any advice would be great help. Many thanks NSD

Dude U R the BOMB

Hi, thanks for your videos, they are very instructive. Maybe you can help me, I repaired an AW55-55SN AF33 transmission of a 2008 Chevrolet Captiva and has the problem that does not enter the fifth gear and "kicks" from first to second, I change the three linear solenides but the problem persists .... Any suggestions or ideas about what the problem might be? Thank you very much for your attention.

Hiram, you're fantastic ... an asset to any business! I previously overhauled (well, assisted my journeyman) Borg Warner Jaguar XJ6 boxes during my apprenticeship years in the mid 80s ... I'm a bit wary of touching these 'electronic' boxes. You seem quite at ease, what exactly is required on the diagnostic side? Here in South Africa Volvo charge +-R45,000 (+-USD2,800) for a recon XC70 (P2) gearbox, I could do it for substantially less... if I had the diagnostic machine.

Great video Mr.Gutierrez, i currently have an issue with one of those, its hard shifting and when i get to a stop iyou can feel like a hit, it doesnt slip at all, do you think changing the valve body would help?

Amazing videos. Where is the temperatursensor sitting?

yet another great video Hiram.. i have an isue with an chevrolet captiva transmission..(aisin 55-51)...after rebuild with bushing kit instaled seal kit instaled ,cleaned the valve body and everything, not the transmission is harsh on shifting from N to D and from N to R....i also have erro code on 5 gear and toque converter stuck open ...my gues is that upon reasamble of the valve body i mistakely set the "steped" pressure regulator sleeve...could be this the case Hiram?

You have convinced me that I will never try to tear down a transmission. You are a professional, and I am not. I hope flushing my Volvo's transmission will fix my problem. If not, I will either have it professionally serviced or scrap the car. I'd like to change the filter. Why in the world did they bury it inside the transmission?

Did you break off a bolt head at 2:35?

Are you able to do a transmission over haul video on a transmission for a 2005 Volvo v50 t5 I’m trying to find a part number to post here but I’m uncertain . And or post tools needed for the job ? By the way amazing videos that you post any help would be greatly appreciated 🙏🏽

The video is fantastic . However, you did mention in one of your videos that you do not want to be contacted by phone, but how about by email? I want to be your on line trainee. Your are amazing. Bisi

My car turns on, I put it into drive and hit the gas pedal and it just revs, I put it into reverse same thing, went into manual mode and same thing it’s like my gears aren’t engaging... then when I went to put it in park it makes a noise in the middle between neutral and park. Help. It’s a 2005 Nissan Altima SE-R same transmission as this one. If it’s the valve Body I’ll change it if not I’m not fixing it. Any info will help

Great video. Please advice. On AW50-42LE. My back cover middle teflon seal groove is bad and cannot take the teflon seal. Can it work with the two remaining outer seals?

hey how's it going been watching your videos and have to say they been very help full 1st question I have is I'm gonna replace my valve body on my maxima and I wanna know where can I get the gasket for the suction cover and 2nd question is when I install the valve body the lever that's on top of the valve body is there anything I do with that cause it seems loose does it grab on to anything or is that going how it is thanks

I tried everything I can think of to keep this assembly together while I reinstall it into the transmission please if there's a tip you can give me I really need some help

DAME YOU ARE GOOD

great video, going to subscribe.. I had a failure a Chevrolet equinox, AWD AW55 tranny. quick question do you have any videos on how to dissemble the pump assemply.. I have taken out the 4 bolts, clutch packs, spring compress ring, and the larger snap ring in the center. Definite pump failure due to clogging of debris, large metal debris of 1mm in size can be seen near the center input shaft, I just cannot figure out how to remove the pump to show the client...

Muchas gracias por estos videos aunque no soy Mecanico me ayuda a entender que pasa con mi carro, pero tengo una pregunta yo tengo un 2005 nissan maxima SE y tengo un problema de ves en Cuando la transmicion se queda pegada en 5 pero apago el carro y lo vuelvo aprender si vuelve a quedar bien me Han dicho que Es el crankshaft position sensor Otros me dicen que nesecito transmicion nueva y tambien tengo el problema de que Cuando devuelven cambio de 5 a 4 lo hace duro se siente un halon gracias hermano .

just got a call from my local tranny repair man. He said it will cost me (approx in USD) 2500 $ to fix my AW55. Apperantely there are some worn out clutches and some solenoid failure. With this awesome video i will do it myselg. Keep on with what you are doing ! A+

Cool video. What is the trick to getting the pump back in this unit.

Hiram, tus videos son lo maximo, te felicito, quisiera saber cual es la presion correcta para el SLU y SLS es lo unico que falto, y quisiera corroborar contigo si la presion del SLT debe ser 2 Lbs en el manometro, gracias de nuevo y esperando seguir manteniendo contacto. Silvio Romero desde Venezuela. Un abrazo.

Do you have a DVD on dis-assembly, inspection and rebuild of the AW55-51SN / RE5F22A Transmission? I purchased a DVD on the 4T65E transmission and rebuilt a couple with success. The DVD was more detailed than a manual because it showed what to look for to replace and you could stop the DVD and never lose your place in putting the unit back together.

***** love this video. Not many people go as in depth as you.. I have an issue with a 01 Volvo v70 xc transmission. Park is loading the engine like its in drive and I think it would move if not for the park pawl because the car moves forward when you start it and you can't Rev past whatever the TC stall speed is. Reverse doesn't work, it's like reverse is fighting drive and reverse at the same time so it just doesn't move at all. Neutral is DRIVE (yup I can go forward in drive) , and drive is drive. It seems to shift through all the forward gears (car is not registered so I can't drive it but in my jobs parking lot).. I'm a professional auto technician but we don't do transmission overhauls.. This seems to me like a solenoid or valve body issue, but I don't know. Where would you suggest I start my diagnosis? I have access to snap on modis scanner, and Mitchell on demand (not a fan of it but it's what my shop uses) Ohh and i have a dtc for 3rd gear incorrect ratio in the TCM.

I'm having trouble putting the pump back in how do I install it with out the drums falling off

Hi Hiram. Thank you so much for posting these vids for us. I'm Fascinated by transmissions and have tore into a couple. Please answer a question. My af33 has no engagement in any gear even though the range shaft is moving with the shift cable. Short of the detent spring being broken or misaligned, will a stuck closed slt solenoid cause no line pressure? Any thoughts? I did get various tranny codes but they went away and didn't return after they were cleared. That's why I'm suspecting the broken detent issue over sticking solenoids. Thank you in advance. Keep trannying!!!😁
