TIM :

HELLO have you service the trans yet--- new fluid and filters?

JACUSTOMER-cdxethtp- :

Tim,

JACUSTOMER-cdxethtp- :

Transmission has not been serviced. As i indicated the oil is cherry and very clean. Fluid was changed when dealer instaled

JACUSTOMER-cdxethtp- :

new converter under warranty, transmission has lock up problems.

JACUSTOMER-cdxethtp- :

The transmission shifts ok in all other respects. Keep the 29 bucks or get me a real answer! roy

TIM :

I wanterd to establish a starting point with some basic info--I will opt out and someone else will assist you

JACUSTOMER-cdxethtp- :

Since tim opted out - my real question is this and I had hoped a service manager with 20+years experience with Jeeps could assist in diagnosing! This transmission is computer controlled - Are we looking at a possible reflashing of either the transmission controller or the car's ECM at the dealer on 8/16/10 . The only other thing that I can think of would be that there is a bad relay that controls the shift or a switch in the transmission.
