Transmission Reprogramming
Hi guys,
We just bought a 2004 GMC Savana 3500 5 window with the 6.0 gas, and are getting ready to pick it up.
The seller replaced the transmission, and is saying we need to get it "reprogrammed" before its ready to go, but they also say the bus drives well as is before the reprogramming.
Does anybody have experience with transmission replacements and reprogramming? is it necessary if the bus drives well as is? is there the possibility of engine or transmission damage if we don't do this reprogramming?
Thanks so much!
