Split the tranny in my 93 GMC 3500 Crew cab dually 454, 4x4 like a ripe watermelon. Replaced it with a 94 4L80e with a shift kit.
Feels like someone hit me from the rear when it shifts. Despite what everyone told me before I put it in, I read that the 94 has
an upgraded pressure control solenoid that can cause hard shifting in earlier trannys. If the new PCS is an upgrade, I would like
to leave it in there. How can I make it work with my electronics? Should/can I just put a 93 PCS in?
I also have another 4L80e that has a tag indicating the year 2000 on the side of the case, just ahead of the normal location. It is
obviously not that late a transmission as indicated by the shifter, cooling line locations and main connector. It is labeled as a GM
replacement reman. I there any way to tell exactly what this is?
