2001 Chevrolet Suburban 1500 Question: shifts in all gears except reverse

no warning, just did not work any more replaced module on transmission, no help. -
Answer 1
Reverse is controlled by the manual valve and not any of the electronics. If that gear is missing you have an internal component failure and you will need to see a transmission shop. -
