Vehicle make/model 1999 chevy tahoe lt
Mileage = 166588
Engine size = 350
dash lights = ABS and Check engine light
codes = P0502
work done prior = Unknown
work done to repair = none
tech = mw
question = I was driving and the ABS light came on. When I applied the
brakes the started grinding. Afterwards the transmission started
slipping and wouldn't shift higher than third at 3000 rpm's. Does the speed
sensor control the shift rate of the tranny and if so how do I replace
it.

Hello and welcome. sounds like you have multiple problems here. Code p0502 is a vehicle
speed sensor circuit low. It is on the tailend of the trans.(or tranfer case if 4wd) That does play a
part in the shifting patterns and abs system. First thing you need to do is get the ABS computer
scanned for codes as well, that is the key to start diagnosis. Grinding in the brakes may be just
normal brake problem, but if abs activation is what you feel, then a problem in one of the front
speed sensors is most likely cause. Need to get to a repair shop and have all these different
systems checked out.
