Just started today doing this. Reverse works fine. When I put it in drive shifts in good at first but then feels like it goes into neutral then into gear again. Tried shifting manually and it shifts good. What can I check. Fluid was changed 4000 miles ago and it is still full. Also changed the TPS like 4 months ago. Could it be the TPS is bad again. Got the TPS at autozone and still has warranty.

 

try and dial it in again with an ohm meter. Should read 4.89 or so on the top end and 3.89 or so on the bottom end.

 

It's the TCU, but where can I get one? Does anybody have a Autozone or Oreilly's part number. Went to autozone and they can't find it on the system.

 

junk yard, Jeep, ebay. No part stores sale them.

 

Bummer. Well to the junk yard it is. Thanks.
