i just had another transmission put in 2 days ago but now my anti lock {abs} keeps coming on and when i put my feet on the brakes it makes a strange sound can you tell me what that might be
(1) Answer
Your hearing/feeling the anti-lock brakes applying. This can be due to dirty or loose wheel speed sensors in the front wheels if you have 2 wheel ABS, which is what I believe this has. If you have rear ABS, then I'm not sure where the rear sensor is, could be in the differential or the wheels.
I would check for diagnostic codes in the ABS module and see if anything was damaged during the transmission installation.
