Hi. If the codes are cleared from the ecu then the truck should come out of limp mode. You need a scanner to clear the codes.

Customer: replied 1 year ago.
OK but what caused it to come on?
Expert:  EricFromCT replied 1 year ago.

Likely if the transmission is running hot. Perhaps from a plugged cooler, or if the vehicle has been driven at higher speeds with the overdrive off. A faulty shift solenoid can cause limp mode as well. Also a concern with the throttle body can cause limp mode. But with the trans temp message, it is likely from that.

I have seen problems with the trans temp sensor as well on those.

The Transmission Slips at times just going down the interstate, it has 202,000 miles on it I just figured it was getting old, does all of this fit together causing the same problem; Slipping and the over heating?
Expert:  EricFromCT replied 1 year ago.

Yeah that makes sense.

Customer: replied 1 year ago.
Is there a way to bypass this sensor so we can get it home
It is only going 40 miles an hour
Expert:  EricFromCT replied 1 year ago.

There is not. There also may be other slippage or shift codes in the computer that are also putting it into a limp mode. It is not just temp related. Best thing is to get the codes cleared and drive it easy for a while.

Customer: replied 1 year ago.
We put the scanner on it and it does not show any codes????
Expert:  EricFromCT replied 1 year ago.

It may not actually be in limp mode then. When in limp mode the check engine light will be on. The transmission just might actually be slipping so bad that it wont move fast and is overheating.

Expert:  EricFromCT replied 1 year ago.

Sounds like the trans finally let go.
