Did your check engine light come on? Your Neutral Safety Switch probably needs to be cleaned or replaced.

Did you read this current thread?

Cleaned the NSs and still no reverse light and no overdrive anyone got any othere suggestions
Appreciate the help guy and girls
This seems to be a common thang with jeeps and want not is read a crap loud of threads and still no one know how to fix this problem lol

 

test your tps, mine wasnt going into overdrive either, my tps and iac and mat sensors were bad. put the new ones on and now i have overdrive. when i do 65 the tach shows around 2000-2100. before it was showing like 2400-2500 rpms.

 

Try this: start out in 3, listen and feel for the shifts, watch the tach if you have one. 1-2 and 2-3 OK? Move it forward to D while watching the tach. The RPMS should drop and should drop AGAIN then torque converter lockup is achieved.

So are you not getting OD, lockup, or both?

The brake pedal switch will disengage lockup.

 

Alright guys gunna give it a try

 

i really dont know i dont have overdrive sometimes it will randomly go into overdrive and go back to 3 gear

 

what is the mat sensor

 

the mat sensor has a electrical connector going to it on your intake,if your year has it.

 

Oh alright man well know since I've cleaned my NSS it goes into over drive randomly know

 

How do you unplug the TCU
