Thanks Gary. This RU-vid clip was so helpful. I own a Australian 2010 Ford FG which has the ZF6HP26 Trans. Car was going into Limp mode every now and then and became more frequent, car has done 150,000 kms . Went to Ford dealership to scan for codes which were wrong ratio's for 5th and 6th gear. Have rebuild trans with bush kit and overhaul kit and is running sweet. I like your little trick when you were doing A drum with bushing tool.
We have both Gary. 6r60/80 in some of our fords and the higher performing ones use the 6hp26.. guys are building these in Australia for high performance and using 6r80 input shafts which are way beefier than the standard input. Cheers :)
Gary, me again| Dude this is again a life saver, i commented in the other video that i pulled out the insides of the ZF hp gearbox. Now i wanted to take the internals for an inspection and bushing changes to a shop. And i wanted to pay for that in full, now i was to few shop already and anywhere i go, once the shop learns i tore it down my self - they say F*U to my face and decline any work on the bushings or the gearbox.... so wether i like it or not im forced to do this my self
hy, im rebuild the valvevbody with new separator plate, solenoids, accumulator damper and rebuild the torque converter, but the upshifts are still harsh (usually between all gears)if I don’t give throttle, and the second problem is reacts late use break and add throttle. That is bushing, tcm or something? no fault codes and the clutch adaptation values are pretty (around -100-(-200)
Awesome video! Very detailed. After watching your videos I decided to rebuild mine. It worked! Took me a lit longer than you, but learned a lot. I had a 3-4 flare that would go to fault mode. By the way what is the tool that you use to pull out the bushings?
Mine is doing exactly same thing. What did you all replace in yours? All the bushings or just the E clutch one? And the clutches. Do you remember how much you paid for the parts? I'm thinking about talking on this challenge. I swapped mine with a junkyard pull and it's doing this. Smh. My original transmission was doing same thing and I think it started to also slip on 1-2.
Hi am very much impressed with how you work out this gearbox how can i get the kits like the bushes and the clutch plates i do repaires but sometimes it doesn't work out due to luck of proper tools and the repair kits.
I have the 6hp26 the gaebox is responding very well from drive to the sixth gear but when trying to overtake on a hill the kickdow is not responding it like the gear is slipping what could be the cause because have replaced all the clutch plates except the bushes.
hello Gary, I have a jaguar xf with 6hp26 which gives blows to the downshift 2 towards 1, as if the 1 engages later since when I leave too quickly a blow occurs. then I have engine rpm variations from 3 to 6 only when the engine starts to heat up with big vibrations and the problem is accentuated when the road goes up. I have no faults in the computer. what do you think? thank you
Gary so the reason that these transmissions have problems with the E clutch / Overdrive clutch is worn out stator bushing causing a leak so the clutch isn't applied properly?
Interesting! I know everything online Says to use an Arbor press to do bushings but you knocked them in with no problem! I have a question… That tool with the notch on the end of it that you were using to Is knock out the old bushings, is that Custom made or does that tool have a name? Looking forward to part 2!
Hey so on my ZF 6HP28 I've diagnosed it to be a worn stator bushing but was wondering from your experience is this likely to of caused excessive wear to the E gear to necessitate the replacement of the e gear or should replacing the bushings do the trick? or is this more of a depends on the situation kind of thing? Thanks
Hi Gary, could I please ask how you decide to keep the steels or replace ? Do you measure thickness or look for marking. Also what brand of clutches do you recommend ? Thanks so much for all your help.
Gary, now that the repair on the BMW 2004 545i 100k miles appears to be bad bushing, what do you recommend it's done to the transmission shop after it's pulled. I can in the future replace valve body plate and solenoids but I don't have the lift to pull the tranny to replace the internals bushings/clutches etc. Do you know a re-manufacturing facility in the SFCO Bay area Ca. that you can recommend, what should be an acceptable warranty after the repair. Thanks.
Thanks Gary, great video. I asked a couple of places and I am waiting for an answer about refurbishing the tranny. After watching your video I can follow your video and should be able to replace the bad bushing and replace the others as well plus the clutches. Last year I replaced a busted reverse drum on a BMW330i tranny for my son. Thanks for posting your videos. Great help for us newbies!
I have a question about the pilot bearing replacement on a 6hp26 back in the rear shell / output flange area part. Not sure exactly what the proer name is , but there's only 2 pilot bearings. The one that's in the output flange part has 3 steaked dimples securing the bushing in place. Seems like I would remove it like any other bushing and file the dempled / distorted edge caused by the factory steaked dimple and proceed to install a new one? Thanks. Your videos gave me the confidence to rebuild my 6hp19, which turned out great! Thanks Gary!
The bushings appear ok, the bushing kit comes with new ones and was just going to replace them just cause they are supplied. I will check Monday if they have any / excessive play.
As a standard overhaul i always do, however, i do have some customers that just do the rear stator bushing(its really your call, i always do all of them) do you have codes pretaining to 4th,5th and 6th gear? how are the downshifts?
After purchasing the Omega Machine bushing kit a few years ago already (because it was mentioned in this video), it´s up to rebuilding my own transmission. I now recognized that most of the bushing kits on the market come with one or even more punched bushings. My question: Has this any positive effect on durability, or are the Omega Machine bushings still the way to go?
Hello Gary. Very nice videos. Now I feel prepared to do my trans with my little son (4). The 6ho26 in my 530d is now giving me real problems. 1 to 2 hard shifting, 2 to 3 and 5 to 6like a ruber band. Doing a 120 k's and kick down (now even without kick down) leads to emergency run and goes in neutral. It has 330.000 km an a new mechatronic. Now I got a trans with about 60.000 km an I want to chang the bushings before it comes in. My question. Which kit shell I get because you use only 7 bushings in your video and the mentioned kit from duro bond has 14 bushings. Thanks a lot for helping us so much with your very nice videos. Best regard from Germany.
@@PlayBoss81 The 2 smallest bushing (where the intermediate shaft's ends are riding on) are locked in place somehow and changing them - due to the Sonnax manual - requires machining/ grinding away parts of their seating, so I doubt if the replacement ones would be safe in place and decided against putting those in. There were other bushings left in my kit (from Omega Machine, as Gary was using a few years ago) also. At 60.000 km I would (if at all) only replace the stator bushing (as the one most prone to wear) btw - my unit, built into a V8 Jaguar, survived 230.000 km without any problems... In case you need the "small" stator bushing (input shaft diameter 26 mm): I have 4 Sonnax bimetal stator bushings left over from my own rebuild. Schöne Grüße aus 🇦🇹
Gary I need HELP, PLEASE. I have this same transmission in my 2010 550i e60 m sport package model and it been throwing clutch E transmission fault, I live in Kansas and I cannot find a transmission shop that’ll do this let alone at a fair price everybody wants thousands when I can get a rebuilt transmission online for 1500 but theirs no sense in that when I know it’s either these bushings or friction plates in clutch E and clutch D I know that because I had a tuning shop run a diagnostic on it and the clutch D and clutch E output number were way to high causing slippage, is there a way I can send my transmission to you and pay you to fix it?
Hi Gary, I have a zf6hp26 in Ford Falcon with 259,000 km. When cold the rpms have started to cycle up and down 100rpm on very light cruise at 25mph with shudder on slight incline. When warm the transmission is faultless. The symptoms are the tc but do you think the fault is a pressure loss from the bushings, or valve body related?
hey gary. currently. got a 6hp26 was wondering, should there be movement in the input shaft? i had to wiggle it pretty hard to get it to move (maybe.. 3-4mm)? is that okay?
@@GaryFerraro it hasnt been pulled apart or anything it has 126KM's on it. just unsure if the front shaft moverment is normal. have you got a facebook page i could shoot a video though too show you what i mean?
Hi Gary! I have an Australian Ford FG With ZF 6HP26 and pushing around 500-550hp at wheels and the transmission has began to flare/slip under load from 3rd to 4th but drives fine driving normal or even under half throttle what you think may cause this? And is there anything you can recommend to make these box’s stronger ? Cheers
Gary Ferraro it seems to be when cold and hot but not so bad when cold if that makes any sense. That’s only when on gas full throttle. 2-3 is fine 3rd is fine until starts to rev out out and will slip straight into 4th before even shifting into 4th.
2 Things can cause this problem, first is the rear stator bushing, when the bushing wears out it leaks E clutch oil, the E clutch comes on in 4th and stays on for 5th and 6th gear. the other possible issue that can cause this problem are the solenoids. Do you actually have a 6R80? is this a metal or plastic pan? just reread and i see its a ford
Gary Ferraro Gary Ferraro Gary Ferraro Gary Ferraro Interesting Gary I wonder if it is as something as simple as solenoid. But wouldn’t surprise me if it is rear stator bushing causing issues. Yes I believe in Australia we call it ZF 6HP26 which from what I heard same box as mustang use but with smaller input shaft ? Also I have lifeguard6 oil and never been replaced from factory as ford says lifetime oil do you agree ? Box’s has done 200,000kms.
The reason why i ask is on the 6r80 transmissions havent really seen to many solenoid issues yet(i've rebuilt maybe about 7 of these) but the bushings do wear out on these like the ZF units as well
@@GaryFerraro thank you so much for the quick reply, the bushing went it well didn't suffered at all, what I mean by not straight is that when I measure with the caliper along the bushing edges one side might be per say .5025in deep and the other end .5250in. So I was wondering if such a small difference would have an issue? the parts seem to fit all well. Rebuilding my own transmission not much experience CD4E Escape 2005 FWD.
Hi Gary, I have a zf 6hp19 transmission which it's having a slipping / flare issue from 2 to 3 and 3 to 4. This happens only when I'm pushing the throttle a little harder. From 2-3 it's worse, if i accelerate hard, it's kind of start to vibrate(slipping feeling) and then rev up and immediately shifts in 3 gear, and it will also trow a gear 2 incorrect ratio error. It also have high adaptation values on clutch A and B 450mbar and 500mbar Do you think it's a valve body issue ?
@@GaryFerraro 001843-gear 3 P0733 incorrect ratio and 001842-gear 2 P0732 incorrect ratio The transmission it's on a vw phaeton 2006. Code: 4841965 1071 040037 HKN
@@GaryFerraro Yes, replaced the fluid and checked the level at 35 C with engine on. Lifeguard 6 fluid. Also replaced the filter, no metallic parts on the magnets. Also it was 1 liter less fluid when i replaced it . The trani has 200.000km
@@planestuff1892 ok, I would say you either have a valvebody/solenoid issue or worn bushings in the unit causing a pressure loss. What i would do first is get a new set of solenoids and open the valvebody(very carefully) and install a new separator plate. After this is done you must reset the shift adapts or it will work the same way. Do you have a scan tool to reset the adapts?
Hi, Gary. Is it normal to just replace the bushings in the front part of the transmission. I'm doing this job now and I'm not sure if I should do the rear half.
@@GaryFerraro I'm not sure, as this is an used 6HP26 I bought to overhaul and swap out with my original transmission. It supposedly ran just fine. The front part of the transmission looked great, with no burnt clutches or miscoloration of anything.
Hello Gary, I am waiting for a new valve body (error 4e89). In the meantime, I disassembled transmission for inspection. I noticed a strange scratches on A clutch hub. Can I send You some photos with this? I didnt see something like this on your movies.
I bought this set 30 years ago, not sure who made it, I have a small set that i got from harbor freight, but for the A drum you would need large drivers, maybe try googling it, the ones ive seen maybe alittle pricey, if you like i can see what my supplier has
I going to give you my suppliers e-mail and phone, he says he has a master bushing driver set(may be pricey) He is very busy, when your ready, i would e-mail himfirst and just say Gary from AAA-1 Trans gave you the e-mail and i will give him a heads-up you will be contacting him
what a junk transmission seriously I rebuild transmissions its such a shame that an expensive transmission like this needs this kind of work at such low mileage.
