So I'm preparing to do the 4L80E swap and I have a few q's
Got the truck rewired and is running on a 1994 454 4L80E PCM, new bulkhead harness for the trans is built and installed ready to go.
I need to know what needs to be done with the crossmember(s) and mount(s) for the new 4L80E trans and what drive line I need?
the truck is a 1990 GMC K3500 Extended Cab Long Bed Truck with a TH400 in it.
Could I just go buy a new driveline for a 1991-94 K3500 Extended Cab, Long Bed truck?
My plan is to find a rear driveline that will fit for the swap ahead of time, then just do the whole swap in a weekend.
