I am sorry that you have not been helped yet. I just came online and saw your question

When you say transmission service done, do you mean fluid replacement, or a repair done as well?

Does your scan tool communicate with the tcm but not complete the relearn procedure, or does it not communicate with the tcm at all?

Please remember that I am not there to inspect it or test it, therefore I rely on you to provide as much detail as possible, thanks

he told me just fluid change
yes I could communicate with TCM all the time even on live date too but won't let me do a relearn

Ok, when you go to the first step, reset memory procedure in the engine menu, what does your scanner say

i have not hook the scanner yet been busy with work at my shop but the check engine light came on and it's p0500 code a vss I already replace the vss on the transmission the one in the front
Expert:  ebrock63 replied 1 year ago.


P0500 on this vehicle is for the speed sensor at the rear of the transmission which is the output speed sensor.(see attached)
