Low power, tire-spinning 1-2 shift... HELP!
I had to cut the pads off the Suburban rear and welded them under the pickup rear. They align with the shock mounts and were welded/blended into those when I installed them. The pickup frame is shaped differently, so i had to extend the end links about 4" longer than stock. Autozone sells...- bfcg30518

It shifts perfectly normal at part throttle and regular use. Its only at WOT that it will burn tires from 1-2 shift.- bfcg30518

Low power, tire-spinning 1-2 shift... HELP!
Ive also swapped in a set of 3.73 gears and a posi unit pulled from a Suburban. It made a big difference. Today I mounted a rear sway bar from the same donor truck. Had to lengthen the end links and weld the pads on the axle tube but it was otherwise a pretty simple job. The truck handles much...- bfcg30518

Fuel pressure was 55-60psi... so I left fuel pump alone and replaced all 3 O2 sensors with new Bosch units since it had multiple O2 sensor codes and CEL. It seems to be running much better but still feels like its laying over pretty bad when I wring-out 1st gear. Theres still something "not...- bfcg30518

Fuel pressure check is next. Havent done that yet but it feels really lean and lays over pretty bad. It does have a CEL for O2 sensor issue, but I assumed that was due to gutted cat. Also learned that it's a 305 Vortec and not the 350 that we thought... so that just nixxed any upcoming mods and...- bfcg30518

"Did they install the Corvette Servo? I have the same behavior in my LS swapped truck. The WOT 1-2 shift will spin the tires like crazy. Even at light throttle it's a very firm shift." Yes, I'm pretty sure he installed the Corvette servo.- bfcg30518

Low power, tire-spinning 1-2 shift... HELP!
Picked up a 96 C1500 for my son a few months ago. We got it with a bad transmission, so I have no idea how it ran before. $2300 later, we have a fresh transmission that seems to drive and shift just fine under normal driving conditions. No issues whatsoever, other than what feels like a weak...- bfcg30518
