Most common on cylinder E and the intermediate plate. A worn bushing will cause E clutch pressure loss, the clutch starts slipping and trans goes to failsafe.
The link shows the bushings I am talking about:
ZF6HP26 & HP28 Bushing Kit from Omega Machine & Tool Inc.
The trans adaption is trying to compensate for the pressure loss but can only add a limited amount of pressure to the clutch.
Clearing the adaption values usually makes it worse."
By the way I would like to sincerely thank Klaus for his speedy response and invaluable advice in regards to my predicament. I appreciate it immensely.
Not sure what I do now, any advice? Should I go for a rebuilt? A remanufactured trans straight from ZF, or just sell the car and move on? Has any other member dealt with an issue similar to mine? |
ZF told me the same thing about bushing wear. Bushing wear generally happens if drive around low on fluid which is tough to do because the transmission will quickly go into fail safe mode.
I then sent ZF my pressure readings and they changed their diagnoses to bad pressure regulators. This was from ISTA.
