Hello, this is my 1st post on forum because English is not my national language. I'm reading this forum for a long time and it helped mi with a lot problems. I have problem with Transmission in my E34 540. Before i decided to rebuild valve body with zf kit, everything was fine. But now, with rebuilded vb, my car have problem with forward. At d it moves very slowly, tugs at the gear change and displays transprogramm. In winter mode it moves normally, but before gear change the same things happens. On reverse everything is ok, like before rebuild. On diagnostic tool there is code 105 - speed monitoring.
What i check:
- i checked twice every springs, checkballs valves etc and everything seems like in instructions
- replace speed sensors
- oil level is good
- filter OEM
- resistance of solenoids is good (checked under hood)
- gears are displaying well before failsafe
I wanted to extend the life of the gearbox but i killed her
Thanks for any sugestion
Did you remember to hook up the end of the shift lever to the manual valve in the valve body when you put the VB back in?
You replaced the speed sensors and now you're getting a "speed monitoring" error. Have you still got the old ones? Maybe you could reinstall those and see what happens.
whiskychaser, I think yes, all gears engage good when I move shifter, but i will check it again
mrgraybeard, Error appeared on old sensors after installation rebuilded vb, then I replaced it with others without change
Do you know if the valve body from newer 5hp30 with green plate will fit p&p to black plate? I know that in newer are green solenoids but does it matter? My tranny is 1995
Did you install the same, identical valve body gasket and did you compare the gaskets before installing the new one?
There are 2 versions:
1055 327 093 5HP30 old version
1055 327 102 5HP30 new version
I was told by a ZF repair shop that the new gasket will fit instead of an old gasket, but installing a old version gasket in a valve body where before the new gasket was installed, will cause problems.
same is on 5HP18
1056 327 100 5HP18 old version gasket
1056 327 110 5HP18 new version gasket

There is the question. Google graphics says there is 2 different gasket 093(differences in red circle)
093:

093? (that was in my VB)

102: (I instaled this) vb have nr 323

I actually had an issue when I did the rebuild with a spring.
The new spring was considerably stiffer than the old one. No other versions for that part.
After installing it the car was making a terrible clanking with Trans program and no forward engagement.
I tore down the VB again and reinstalled the old spring. All was well after that.
I believe it was for 2nd gear clutch or something. I can look it up I wrote it in the records somewhere if you need.
It can be this. I would be grateful if you would check. Write if you can, which spring number you reinstall.

This is good news because I only compared the length of the springs, not stiffnes. Tomorrow I'll have messy job again
paperplane94, You save my life Same spring, same situation. Thank you
But why zf give this spring in kit?

forgot how to imbed pics.
Super glad it worked! I hope it stays that way.
I couldn't find any documentation on this issue when I did mine. Glad this is on the forums now.
I wonder if this is a problem with the transmission being different or the valve body kit has the wrong part.
I checked in the green tag valve body and there is also stiffer spring. My valve body is 95 and from green plate 99
Such a kit is only sold on the US market, not in Europe. Actually you basically only need the balls and the paper gasket and no springs, cups or whatsoever.
I usually only replace these parts and keep the original springs.
Usually on the 5HP30 even the old plate gasket can be re-used, as it does not stick solid between the plates like on 4HP22/24.
Copy of the thread moved to E32 forum for info.

This is very interesting info. I rebuilt my 5hp30 valve body about 5 years ago, and also replaced the gaskets, o-rings, selector seals, etc. I don't remember noticing a difference in spring stiffness. That e32 is a 09/93 production date and I don't recall if that is the green tag or black tag 5hp30; I got my ZF valve body kit from CTSC and installed every part that came with the kit. Maybe I got lucky that it had all the correct parts for my valve body, it fixed all my transmission issues and shifted perfectly afterwards. I had initially planned to do regular fluid changes after that but I got lazy about it and 100 thousand miles later it still shifts and runs as it should (up to 236k now).
Great to hear you solved the problem! I wonder what the reason is for that particular spring difference? Is it a production date issue with various versions of the 5hp30 valve body design?
paperplane94 - how did you figure out one particular spring of the many springs was the root cause? Did you just happen to notice one was much stiffer than the spring it replaced?
Post the question in the original thread in the E34 forum, probably paperplane94 is not reading here in the E32 forum threads

Part number D159165 appears to be made by Transmaxx, even though it has the ZF logo on the box. Is that kit actually manufactured by ZF?

Revival for closure...
From what I recall, Yes. I noticed the spring was stiffer just by eye, and definitely by feel. The gauge of the new spring was just thicker. The other new springs varied in length but I chocked that up to the old springs being slightly compressed. It was different enough that I stopped to triple make sure I had the right spring in the correct spot. It seemed correct, so imagine the dismay when I tore it apart the second time to reinstall the old spring.
It's too bad I didn't have any calipers at the time with which to measure the differences in thickness....
The transmission worked fine until I had it shop rebuilt last year for other issues like the lockup clutch engaging/disengaging at highway speeds with no load change. I got tired of mixing in the Fixx friction modifier, and even that started to not help. All good now.
