C2500 (91-92 specifies 4L80) the trouble I went through and info I hope will help
#1
C2500 (91-92 specific 4L80e first gen) msd hook up info I scavenged up
I put a msd atomic Tcm on my transmission and this is what I had to do ( I spent 4-5 hours trying to find the info)
hope it helps some one in the future!
So recently I did a carb swap on my TBI 350 with a 4L80(1st year) and the first year of the 4L80 uses a different connector than the 93+
