Hey Gary, thanks for helping me thus far. I just put the transgo valve into the valve body, but before I put the plate and gasket over the main part I wanted to ask you a question. In my ZF master rebuild kit I have the rubber pulse reducer and the metal piece with the rubber ball on the end. In my valve body the metal piece was in there, but I didn’t see where the rubber piece went. Is that one or the other based on make and model?

I am trying to rebuild this vb, the ZF kit came with all new springs but the new ones are either longer with same diameter or smaller diameter but same length. I'm at a loss following the schematic. It regarding spring 55.030. use same diameter but longer or other one or original? this is for an 2002 S6 quattro.

Hi Gary, another great video! Can you tell me what the small spring and check valve in the upper section of the valve body controls and does?

I was originally getting a P0741 code. So I replaced the pressure regulator solenoid and did I fluid and filter change but the code remained. Then I disassembled the entire valve body and put the transgo regulator valve in. I was still stuck in fail safe 4 with no manual gears even after restart. I then replaced the tcm. And got all gears back . Drove well for 4months now I have slippage in 3-4 shift into fail safe and slippage in fail safe also. I can only drive in manual 1-3 until fail safe into 4 then 5 and revs until I downshift back to 3.

I was inspecting the valves and bores and was hoping that cleaning it would help. I don't know if it did or not. I forgot to mention I replaced the solenoid harness also.

Hi Gary, I have a 98 jag with zf5hp24 trans. I have 60,000 miles and no trans issues BUT I have heard these trans are ticking time bombs. A jag mechanic told me 90% of the failures are A drums breaking *** but that 80% of those failures are due to a valve or solenoid that allows too much pressure on the already weak designed A drum. Is this true ? He said the part was cheap - should I have this replaced before it takes out the tranny ?
@GaryFerraro
2 жыл бұрын
Yes, that is correct. The bore wears out on the main pressure regulator valve(lower front half of the valvebody) it creates pressure spikes and blows the A drum. People that know about this had me do the lower valvebody for "preventive maintenance"

Hello, I'd like to change oil on a 5HP24A. I'd like to disassemble the valve body completely, and check everything. Do you have any advice on what I should change (with the hypothesis that everything is normal), like seals, bolts, gaskets ... ? Thank you.
@GaryFerraro

+slklite Change the oil and filter is fine, use only OE filter, aftermarket filters on this trans are no good. I would only recommend disassembly of this valvebody to an experienced rebuilder, there are many small oriffices located in the channel plate section that would have to go back exactly where they belong. The only thing you can do is change the lower front section(this can be done without total disassembly) they are known for bore wear, but keep in mind all the valves and springs have to be changed over as well.

+Gary Ferraro Hello Gary, thank you for your answer. I wanted to clean the valve body because I have some problems with my transmission, and I thought that it could be a good idea to do something like in here : www.bimmerboard.com/forums/posts/527361 forums.audipassion.com/topic/141431-revision-bva-5hp24-zf-dortmund/ About my problems : the gearbox seems confused about finding the right gear on heavy load and uphill roads... But when driving with not a heavy foot, everything seems normal. Sometimes it seems the gear is lost and then, it comes back suddenlywith a clunk (but it's rare)... Thank you for your help !!!

Hey garry, love youre videos, so many shops must hate you for them. Ive got an issue with a ZF 5HP24A in my 04' audi allroad v8. Ironically im a tech at a audi dealership but the workshop manual is pretty light when it comes to information on the guts of the transmission. When the torque converter lock up clutch is in the controlled slipping phase from around 1300-1900rpm i get a cyclic flareing of the lock up clutch going between locked and slipping, over 1900rpm when it goes full locked i have no issues. would you suspect this is a pressure regulation issue from the valve body or more likely the solenoid having trouble controlling oil flow/pressure at low duties? Any help would be great. many thanks, Mike

Question, are there any codes? Can you see live data, wondering what the slip rpm is when fully locked
@ej20tnz
7 жыл бұрын
Gary Ferraro thanks very much for the reply. Zero codes. the measured value data shows zero rpm difference between engine and transmission input when closed. it's cyclic, only when the converter lock up is slightly dutied , when it's in this mode it shows a solenoid valve current value of between 0.30-0.45a lock value is 0.7 and solidly locked
@GaryFerraro

Ok, at zero rpm its locked on. with what your describing, does it feel like a "rough road" going into lock-up?
@ej20tnz
7 жыл бұрын
Gary Ferraro nah it doesn't judder or shudder when the LC is going from open to locked. but I would call the locking abrupt, what I think is happening is the TCU Is asking for controlled slippage of the LC but when the solenoid is dutied and oil is supplied the converter locks fully instead of slipping slightly. the root cause, I'm not sure. Any suggestions would be great. Thanks mike
