Death Code? P0740
OK, so my Jeep just threw a P0740 code. Got the transmission over heated message on the dash as well as the check engine light.

Dealer is telling me $2400 to repair, and $3500 to install refurb tranny.

And I see that the only code in the trouble lists here is bold and in red.

Why is this code highlighted, and do any of you have any suggestions on the wisdom of replacing the trans vs. trading the vehicle in on another slightly used GC and calling it a day?

First clear the code and see if it returns.

If it returns are there any other codes and is this PO740 code active? If no other codes are present check transmission electrical connections, if electrical is fine, check and replace the L/R SOLENOID, TORQUE CONVERTER AND/OR INTERNAL TRANSMISSION

There are 3 different types of codes Active, Pending and Stored.

If you have access to a lift for a day and are good with hand tools you can remove and replace the trans in a day or less. You will also need a new torque converter.

agree with escape. me = wj dumb, but in wk trans codes are deep and regular code reader cannot retrieve.

also. get it out of the dealer. find a great indy or chain trans place.
