ISO tranny Specialist
Looking for someone with knowledge on 4L80E. 1-2 shift slide bang. 2-3 does it every once in a while, but 1-2 does it every time. Hooked line pressure gauge up and talked to TransGo tech over the phone, he says actuator feed limit valve is to blame. Has anyone here heard of or experienced this issue? It's in a '04 silverado with 283k. Previous owner had trans built at 163k. Looking to cripple along a few more miles before overhaul. I have the reamer and oversized valves to correct the AFL problem from the last 80 we built. Going to throw HD2 SK in while I have VB out. Opinions?
