A727 Transmission Rebuild - Part-1 - Torqueflite-8 

I've been a Tec for over 26yrs never got in to transmissions ,just installing them Watching your video I have a full understanding of them. They're fascinating Thanks

Glad you showed the whole tear down. It's part of the business and challenge. Love the brute simplicity of early 727's. +1

I'm looking forward to part 2 of the rebuild. You made the tear down look so easy. I've never gone into an automatic trans before. I'm pushing 70 and I'm thinking that it's now or never. Thank you for that first great video.

I rebuilt a 727 about 15 years ago and it took me about 2 weeks of evenings and weekends and I still had to pull it out of the vehicle and apart twice because I didn't put the piston seals on correctly and a bunch of other stuff. Love your vids Hiram :)

That is a candidate for the pressure washer for sure. I am happy to see that I am not the only one that gets transmissions that have been "dug up out of the field." Love the 727! Great transmission!

Hello Hiram, You mentioned on this that you miss your dad and remember being with him back in the day. I just want you to know, the stuff you are doing on here with your expertise and teaching, I am sure your dad would be right proud of you. God be with you and yours. Allan

Loving this series for sure! Got a 46re that needs some work and this helps a lot.

Hi Hiram. Great video. I'm looking forward to the finished product. I bet these old units from the 60's and 70's are more robust and durable than the modern transmissions with a the plastic parts and the sensitive electronics. Of course the newer units are so compact that they hold so much heat vs the old transmission houses that had more surface area to dissipate heat. Great video. Can't wait for the next video on this old transmission.

I'm only halfway into this video and wondering why you didn't pressure wash all the dirt off before opening it up?

Killer action Bro, thank you Sir! My 28 yr old 4x4's 727 is mint next to that beast.

Thank you for the great video sharing your knowledge.

I love this video it helped out a tone!

Used to drag race a TF727 back in the 80's. Was easy back then to go to the Dodge store and buy 5.0 kickdown lever, Hemi front drum, hemi band, 4 pinion planetary gears, valve body etc. Good strong trans.

Great Transmission is the best of 70's

Gracias, buen video!

thanks for your efforts...

Finally got around to watching this. Brings back memories of when I tore down a TorqueFlight 927 in trade school, although nowhere NEAR as dirty as this one. Too bad I forgot everything pertaining to it. I bet you probably had to call Safety Kleen or whoever it is that you have change your parts washer solvent and had em come out and change the solvent in your case washer after washing off that much mud. I have a few boys come into my shop that do a lot of muddin in their 4WD's that I thought wrote the book on stupid as far as gettin mud all over their stuff, but they ain't got nothing on this.

Best trans ever made

727 / TF8 was fitted to loads of light duty trucks and buses in the UK in the 1990’s. This was the first transmission I learnt how to rebuild. My old boss used to buy a container load of core units from the states so we had parts. UK ones had a shorter tail stock and a deeper sump. We used to see loads where the low / reverse servo used cock over in the bore, that and the low / reverse sprag used to spin in the housing, or the rings on the input shaft used to wear groves into the pump housing. Or the low / rev drum used to pick up on the governer housing.To be fair they were built to last, not made out of pressed tin like the newer transmissions were.

Great video. This will help me a ton on my rebuild. I'm just curious as to if you ever got around to making a rebuild video after the tear down? If not is there one that you know of? Tearing down one is one thing, it's putting it all back together that can be tricky. Thanks,Damian.

Great video. If you come out with the rebuild video it would help me personally a ton! You can tell you have been doing it for a long time and know your stuff!!! 👍

Love the channel Hiram! I especially love these older rebuilds even with all the dirt and grime. Did you get a chance to post the rebuild of the C6? I remember seeing the tear down inspection.

that trans is nastyyyy, should have pressure washed it first

Part 2 of the petrified 727 rebuild ? ~ Or is it still soaking, to get it clean?

excellent torque flight,,parts tutorial.

happy father's day to you, hiram

thks great info u r a treasure man

I'm two beers and three tacos away from starting the exact same process this afternoon for my '76 Scout. Wish me luck.....(;-)

Really enjoy your videos. Would really like to see a rebuild of a turbo hydro 350 or 400

What happened to Part 2?

Did he ever make a part 2 I check his videos couldn't find it. I really could use it

is there a part 2?

Excelent You know what You do.

Man your a magician! I just pulled mine. Its the second time i have ever worked on one, the same one. I am having a shit of a time tearing it apart. Any recommendation on a complete street/strip rebuild kit?

im going to be rebuilding a few AMC 727's from some full size jeeps. besides the bell housing bolt patterns are there any other difference between the Chrysler and AMC 727's?

have a 727 with long output shaft does anyone know if I can replace the output shaft with a short one to bolt up to my transfer case?

One cool thing that I have learned is that I can get a deep transmission pan from the newer model deisel engine transmission and it will fit right on my older 727 a lot less expensive than the after market pans

Hello Hiram I'm Sha'ban from saudi arabia.I hope to help me to solve the problem in my car ford taurus 2010 limited. The problem is that there a is shaking in the car when resuming the acceleration while driving in low speed on the 4th & 5th gear(60-100km) but when accelerate harder that shaking disappears.Some technicians said that i have to rebuild the gearbox and some of them said that I need to change the control module with 2 sensors! What solution you think to go with?

was it used as an anchor . love to see the assembly , especially adjusting the bands

for what it's worth i enjoyed it, and i'm glad you are using the fan. It's far to hot down in Tejas for you not to be using one. ;)

just a side note. up to 65 that trans had a rear oil pump. which let you push start it. but NOT after 65. also if it bangs hard going into rev. pull the gear shift all the way to low then rev. the reason is when you go straight to rev it loads the servo with 300 psi . but if you to low it loads it with 150 pis. then when you go to rev you only hit with 150 psi.

Do u know which line goes out and which one returns for external cooler? thanks

how do you clean this transmission? maybe show few little clips on the cleaning also do you charge the customer extra? great raw video I will be waiting for part 2 thanks Hiram

I have a '78 W150 full time, 360 cid, I want to put a 440 in it but don't have a BB 727 fulltime trany, can any 727 be used ? It bolts directly to the transfer case. I have 3 BB 727 CAR trany's, will any of them work ? Does it need special output shaft ? do I need to open up the transfer case to separate them ?

what happened to part 2????????

They were still fitting this transmission into small buses and bin wagons in the UK in the late 1990's. I know, cos I used to rebuild them! What did they call the later one with the overdrive?

Hey I know its been a while. After tearing Tranny apart Its impossible to separate front and rear clutch. Any ideas? Maybe from pressure or heat they got stuck or seized...How can I deal with this? Please help!!!

How do I get part 2 and 3 for the A727 Torqueflite rebuild

You really know what your talking about. I have a 727 exactly like the one in this video. I am having a problem with my tranny revving after 5-10 min of driving. When i replace the tranny fluid it is fine for about a week or 2 of every day driving. then back to the original problem. I have looked all over google and the only thing i can think of is my transmission speed sensor? Do you think this is it, or do you know of anything else that could be an issue?

Three years later, where is part 2?

what a mess, I think I would of cleaned it up first for ya bro

Torqueflite a demon

is the 727 an easy transmission to build compared to the 4l60e.

I have problem with the reverse applies but has no strength to back help me please

: see how word the transmission electronics and see one first transmission it's wonderful.

When do the follow up videos come?

will a broken Reverse band cause anything but no reverse

how much different is an A904/998/999?

Hiram, I just came from the theater where I watched Jurassic World. Where did you get this thing, from an archeological dig. Was it buried in the Brea Tar Pits. All of that moss growing on it made it look like it came from 1000 years ago. Did you jump into your DeLorean Time Machine to bring this back from 50 years ago. Holy Flux Capacitor man.

How many years have you been rebuilding transmissions?

Question Hiram, can a torque converter be unbalanced? If so what do you think would cause this? This is for an auto trans on a 92' accord. I've read posts everywhere about the car idling rough in gear but stopped. Everyone talks about the mounts and timing and cleaning the throttle accessories, heck some dealers think it's normal. Just thought to ask the one guy I've seen so far who knows the parts like no other. By the way, love your videos. Keep em coming! Patna.

I'm trying to diagnose a leak that's coming from inside the bell housing on my Jeep 30RH/A904. I've replaced the pump seal but it doesn't seem to be the problem, the torque converter looks good and is dry when I pull the transmission. Also the vent hole in the pump is dry. But when its running it drips fluid out the housing like crazy. It's definitely trans fluid, could it be the pump gasket or O ring? Or maybe the pin plug? Shifts OK etc.

when are you going to do the reassembly video

I find it disrespectful to bring something so filthy to a such a highly skilled technician like yourself. I hope you charge them extra for your effort.

onde vc encontrou essa transmissao hiram? kkkk

Could a regular person that works on their own cars realistically rebuild a 727 torqueflite transmission?

Actually I'm more interested how a throttle shift down linkage works on a 727 or 904. Or how a Lokar cable takes its place. Or what to look for when you drop the trans oil pan to inspect or tune. I know you can't magically make a video about all this but just a thought.

are you ever gonna do a 46re rebuild?

Where is part two? Thanks for part one.

I’m guessing part 2 was never made?

I cant find part 2 or 3 Etc..

part 2 or 3 ?????

This is in my future... either that or just swap it out for a salvaged one. Fun fun fun...

im shocked you did not tell them to clean it, or you took the hose to it.

Hey man, what's happening? I remember the "Dukes" and the old 727. They were a great working and tough trans in their day. I bet it's gonna cost a bit of bread to rebuild that mess.....LoL.

where the HELL is part 2

Ive enjoyed watching your videos. How many years did that style of transmission last. I have a 91 Dodge D 150. The tranny is starting to slip when I first start it up and attempt to take off. How do I find out if its the pump or the friction disc ?

where can I find transmission rebuild kits I have a 74 Dodge Monaco please help no reverse I think it's clutch band or the clutch packing please help thanks

KINDLY THX VERY MUCH can i contact with you

Somebody get this man a power washer

What ever happened to PART 2 ?????

wheres part 2

Where is part 2?

Never seen such a dirty transmission, looks like it was lying a in a bog somehere. Cleanliness would be the first thing for me as well. I wouldn't want all that dirt going into the inside, but hey what do I know. Good thing you know what your doing. I restored some cars that looked like that. A diamond in the ruff 😃

There is a nice reusable pan gasket from Chrysler that works far better than any of those cork or paper gaskets. Part number 2464324AC for the big torqueflites (727 series) or 4295875AC for the 904 series.

Where is part 2???

Hello Friends, i need a little help, please, i have a Dodge D100 1974, with a motor 318, and a transmission 727 tf8, and i lost the dipstick to the oil of the transmission, and in my country is very hard to buy one (venezuela), and i want try to make own one dipstick, but i need the meassurements of the dipstick original, the min and max, and longer of the dipstick, pleaseeeee.... pleaseee... to no break my transmisssion... thanks thanks.

No part 2+? ....bummer

hi hiram i rebuild 904 transmission 1953 dodge and a dodge 727 trans in a van

Pressure wash please. Weather or not the customer brought it to you this way no transmission should ever be disassembled this dirty. Pressure washing the case will save you so much time and frustration. even the time in cleaning your table and the wear and tear on your tools is an incentive in cleaning before disassembly. Nice Ingersal by the way.

man why would u attempt to tear down that transmission and compromise the parts inside when u can power washing it and wire wheel it and have a good clean platform to work off of? it's double working.

Never would have brought that anywhere in that condition.🤔

Why wouldn’t you pressure wash this unit before beginning?

C'mon Man! Where is part 2 - like 4? Get'errr done.

that customer was quite an ass hat for bringing in that trans in like that. i mean damn, take it to the quarter car wash and hose it off. i hope you charged extra to deal with all that mud.

that's what a transmission look like after being in the bottom of the lake he went fishing and that's what he caught.😂😂😂

WTH I subscribed hoping that you have part 2 and whatever else on the Mopar 727 Restoration and all you got on your site is part one Waste of time

I would have told the customer that I charge 399$ for their being lazy ...so either take it home and clean it up as best you can ..or pay me for your laziness

Holy crap looks like it came out of a truck ..

So, it is best to disassemble the unit with the mud still on it? Ok.
