Hi everyone, I have a 1989 gmc k3500. It still has the original 454 but the original 3 speed quit on me a few days ago. So myself and a friend look around our yard (scrapyard we work at) and see a nice looking trans that looks like it will fit. So we yank the old trans out and plop this one in--not much else to do right now so why not? Turns out it was a freshly rebuilt 4 speed out of a 2000 chevy 3500. It fit just fine but there are electrical connectors on the side and the 89 obviously doesn't have the wiring. Truck moves again but it doesn't shift because there is nothing telling it when to shift!
My question is, do we have to pull this one out and get the correct trans in or is there a way to bypass the wiring or wire the 89 to work with this trans?
I know I will take a lot of crap for this, but I feel like it could also be helpful for others to know if there is anyway to swap these different year transmissions. And yes next time I will make sure I swap in the correct parts.
