I did a search, and I couldnt find someone that has had ABS light problems for the same reason I have. I recently installed a GSR tranny in my 97 LS. After the installation the ABS light was on? Curious.. I took the front wheels back off to see if one of the sensors was broke, I couldnt find anything that had been broken. If the wires that go to the sensor were stretched to much when folding the knuckle assembly back could that make the connection to the sensor bad? Is there anyone else that has had this problem? Thanks for any help...

 

I've had an ABS light go off before and suggest you do the following:
1) Make sure your ABS reservoir has enough fluid.
2) Pull the code from the service connector.
