4l80 swap vss trouble Hey guys I need help. Have 03 silverado. 5.3, 4l60 4x4. Turbo. Smoked the 60. So I had an 80 built shift kit fti stall. Blablabla. He's the problem. I Repinned the harness brown and white wires. Then I ran the second iss to pins 22,23 on the green block. Sent it out to current performance for segment swap. Get it all done. Take for test drive. No speedo, and dtc for vss. Tcm is confused and ran like crap. Any help will be appreciated.
Impossible to diagnose over the internet without more information. If you had a way to post the tune that would help eliminate one of the variables. It could be the tune, the transmission, wiring, etc..Its going to be hard to narrow down if you dont have the tools needed to diagnose it.

I have someone that is going to pull my tune. After checking all connections and wiring. And hours of forum hunting. I'm almost certain it's in the segment swap. When the guy pulls my tune I'll post it. After checking the wiring yesterday I tried again. These were my dtc p0502, P0753, p0758 and p1860. Not sure if you pinpoint the problem with this combination of codes.
