Won't shift into overdrive after 3inch lift installed.

Recently had a Rough Country 3.5 inch lift/level intstalled professionally in the front and 2 inch in the rear. About 15 mins into the drive home I noticed a "traction control off" light on as well as not shifting into overdrive. Couple days later drove out in the country and worked fine for 20 mins then wouldn't shift into high gear. Any thoughts or ideas? Thanks!

 

No idea.
Welcome from CO.

 

It could be a number of different things. I found this online. Maybe it will help you figure out the problem(s).

Ok thx! Everything was working fine untill the lift was installed. Now it won't shift into high gear and "traction control off" light is also on. Loose wire? Low transmission fluid? Any ideas?

 

Zero point calibration.

 

Is there a write up for this anywhere

 

Write up is pay 100 bucks to the dealer and have them do it. Or. Do a search for shimmying thr yaw sensor. May not be your fix. Bit could be

 

Possibly overstretched an abs wire. i would pull the codes to see what wheel.

 

Seems like a dumb question, but just going with the basics first...
Have you tried pressing the Trac control button?
Tried to disconnect the battery for few mins? The shop should have, but if they didn't, the truck may be trying to sort out the before/after effects.

In addition to checking any codes and wires, confirm if the shop put in any diff spacers (or not)?

Does it slip in any of the lower gears?

 

I thought ZPC is supposed to address the computer's ability to relearn the change in pitch (nose high) after a lift as it relates to the Vehicle Stability Control. Does it also address transmission shifts? I would've guessed the ABS wire but maybe they're all interrelated?

 

Welcome from CO! I'm really glad I have a 07....I hate..................

 

Thanks for all the input. What should I do first?
1.) Disconnect battery
2.) Check abs lines
3.) Zero point callibration
4.) Shimmy yaw sensor
???

 

What size tires are those? Really like the tonneau cover!

 

Stock rims and tires right now.

 

Zero point Cal should be done. Does it have anything to do with shifting .....no but when in limp mode tranny shifting can be affected. I blew a reverse light fuse and went into limp mode. No manual shifting. Crazy.

 

have it scanned for codes. the code will tell you the problem area, if you have any codes that says circuit high or circuit open for speed sensor you have a streched abs wire. or it will tell you if zero point or yaw rate need calibrated. unless you had the steering wheel way off center after the install, i doubt its those, i have never had to do it after a level install. but i have seen plenty come n after they did a level kit and had open in one of the front speed sensors where they overstretched a wire.
