First signs of Transmission Problem.

[Cisc0]

Hello all,

So my lil' 2002 3.0i with 93k miles decided to show its first signs of transmission wear/problem. This morning while exiting from freeway I felt that hard 2nd to 1st gear "lurch". No warning on the cluster, so I kept driving. It did it again on deceleration from 2nd to 1st. It had never before given me any signs of gear slips or this type of "lurch". To my knowledge it has never had a trans fluid drain/fill (i'm 3rd owner, got her @ 80k). I know everyones case is different and going by the searches the first step would be to update the software. Any other recommendations?

Also, can someone tell me which trans I have.. ZF or GM?


Thank you in advance.
