UPDATE : 4-18-2017
After contacting ZG Genuine Parts (Klaus) I received the following message:
"I believe you have an internal issue, bushing wear would be my guess.
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?
