Engine Mechanical problem
2006 GMC Sierra V8 Automatic
Hi there. I own a 2006 gmc sierra 2500 V8 6.0 eng. with about 170,000 miles,the transmission is shifting very rough, the gears kick in very hard. I replaced the transmission fluid and and filter and it did not improve at all. Also this past weekend I came back from work and it was running, but the next day when I tried to start it it would not start, I replaced the ignition relay and it started but it stalled again after 20 minutes of use, I tried to restart it and it wouldn't, now it starts and runs for about 1 minute and it stalls again and sometimes it doesn't even crank.
