Hello,

These vehicles primarily have shifting issues.
Common fault codes are P0716, P0776, P0717, P0777, P2714, P2715, P02723
Typical issues are loss of reverse.
Hard shifting especially in 3rd and 5th.

The fix is the remove the transmission and rebuild.

Let me know if you have any questions.
Thank you.
