Just had all the seals replaced on my transmission ,all were leaking.Before truck went to shop the milage display and cruise control did not work.Got truck back and everything works great.Can anyone tell me why,I do not understand.The only work done was on the seals.

 

im going to venture to guess, you had a blown fuse and the scan tool wouldn't communicate cuz of blown fuse(probably jumping the gun here, dont know what fuse is with which circut but sounds like what happened to me), tech put new fuse in to scan and didn't have the service writer write it down

 

Faulty speed sensor replaced or repaired during rebuild.

.

 

All the shop can say is they reset computor.Whatever I am a happy customer.
