Hello all
I just recently bought a very neglected 1995 XJ12 car with some issues.
Among other issues the previous owner was trying to fix a problem with the 4l80e transmission not shifting into OD.
Unfortunately his "solution" was to hack up the factory wiring harness to try installing push buttons to shift with.

He also cut off the center section of the exhaust.

If anyone is interested in seeing more details please take a look at:

detail of the add-on transmission gear shift switches

Rust on the rear quarter panel

 

The transmission on the V12 is different as the GM X

There is a TSB with the issues ( maybe ) and ungraded manufactured transmission with the orange dot

TBS coming

 

Sorry but I am not completely understanding your reply.
Can you please elaborate?

 

Looking for TSB

There was something about the proper GM transmission service level to be accurate

I don't have the GM transmission
