I have a 2007 Silverado and have had problems with the transmission since approx. 900 miles. It started with a grinding noise being made when shifting to 2-3 gears. The first repair made was replacing the 3-4th plates & piston, low roller clutch, reaction carrier, and internal gear. I started having problems again round 2300 miles. They then had to replace the housing, oil ring, valves, and gaskets to repair it. I was already upset because I wanted a new transmission the first time I had issues and the dealer said GM refused. Gotta love GM... Not... It was fine for a while and it started to have problems again but the dealer has said not to bring it back till it dies. I have close to 20,000 miles on it and it still is doing the same thing, goes into 3rd hard when shifting or slips into 3rd when shifting. It is frustrating and I am attempting to find someone to replace it regardless. Has anyone else had any of these issues?

| My 2006 gmc 1500 with 5.3 v8 4x4 and automatic trans gives a thump when shifting at low speed the shift is at around 15mph.when in traffic or driving in a development. It only happens when you creep up on the shift speed. If you can go a little faster it shifts through smoothly. the truck only has 10000 miles on it. i had a 2004 envoy wjith a 6 and never noticed this. Any advice thanks. | |
| I just got the tranny rebuilt and the trans-go kit installed.Now when its cold it has really hard downshifts but when it warms up it shifts ok.any ideas from anyone??? | |
