I just put a new tranny in my truck and now 4 wheel won't work has a service 4 wheel drive light on it sucks 1 problem after another yes everything is plugged in ANY IDEAS????????

 

Service engine light on? If everything's there and eveyrything's hooked up, sounds like an electrical problem. Any change in the pcm when you got the tranny changed? Fluids ok in the transfer case? I'm assuming this is the autotrac, correct me if i'm wrong.

 

Did you unplug the 2 plugs from the shift module on the drivers side of the tranny? make sure no progs got bent.other than that make sure all the plugs for the encoder motor on the transfer case are connected.

 

yeah everythin seems to be ok ive checked it all more than once!!

 

ys i put a new shift modulator on today everything seems to be plugged in

 

Do all or any of the lights on the 4x4 switch work?

 

did you get my answer this is my first time being here and kinda lost yes 4 high is lit but relays wont click it is a service 4wheel drive message if that makes a big difference

 

Does the tranny work in all gears, does the PRND321 all work right?Will it go into 2wd

 

allgears work drives in 2 wheel great shifts awesome just no 4 wheel

 

Did you have any problems before the trans install?
