Hi everyone I just finished installing a rebuilt 4L60e into my 2000 Silverado. The truck drove fine for the first 50 miles or so. Now, while in drive I only get 2nd gear, 3rd is second, and reverse is fine. I'm also getting an occasional shudder while coming to a stop. CEL is not on. The tranny came with a 3 year warranty which is why I bought it.....but I dont want to pull it out again. Is there anyway to over-ride this temporarily? The shudder really has me worried.......I'm thinking torque converter. Fluid level is fine and I checked the wiring harness, ect.
