Probably have a bad wheel speed sensor or a bad connection somewhere on the harness. Can you inspect the wiring to the wheel hub? My guess is that something got pinched when the trans was removed.

I just went through this entire dilemma recently as I just had my transmission rebuilt. I was having an intermittent TRACTION ON message when turning the wheel and accelerating any bit, as well as Service Traction Soon along with ABS and Trac Off lights....I had changed both front speed sensor harnesses, checked ABS module ground, swapped out the EBCM (Electronic Brake Control Module) with a known good module, all front wheel bearings and sensors were less than 15k miles old, and we replaced them with Timkens, so we know they couldn't have gone bad that quick. Turned out, with my car up on the lift you could wiggle both front wheels all over the place. Tie rods - OK, wheel bearing - OK, turned out the axle nuts on both front wheels were loose. Tightened them back up to spec, and all the lights have disappeared and we haven't had them come back on since..I guess the axles were loose in the hub not giving a good enough connection to the sensor or whatever.


Just something for you to check. I had the same problems, pulling out of driveway or parking spots where you would turn the wheel and give it gas, would illuminate the dash like a christmas tree.

I hope you get this fixed, because I know it's annoying as hell.

If the speed sensor harnesses check out, I'd make sure your axle nuts are snug. If you would like to try swapping out the EBCM I have a known good working one.

took the car in today for this and they diagnosed a bad left front wheel speed sensor however they rerturned the car to me with out replacing it and now it works fine and my steering (which had some wierd play in it that could be due to a loose axle nut) is now perfect. so whatever they did to diagnose it seemed to fix it what dumb luck lets see if it stays that way
