2003 Trailblazer I'm at 327500 miles. Never had the engine open but I'm getting a valve tick sometimes now. Bought it new in september 2002.

Thanks for the answer. that relieves my mind a bit.

Hello, I have a 2001 Silverado 2500HD with a 6.0L engine and a 4L80E transmission. I've noticed recently that when I'm cruising along on the hiway and I back off on the throttle briefly for whatever reason, when I come back up on the throttle the torque converter will unlock briefly then...

Thanks for the tips on the Shudder Fix and Lubegard. I'll definitely check them out. It is the original transmission. The main thing I'd be looking for with the shift kit would be restoring pressure due to worn valves. I would also like the PWM eliminator. Beyond that I'm not trying to...

I used the newer Dex VI fluid and did a total flush. I used about 14 or 15 quarts in the process. Changed the filter and pan gasket too. I was amazed at how clean the inside of the pan was. Only a light smear of darkness in the pan that wiped right out. No metal or other solid material...

Hi all, First post here. Last year the axle engagement mechanism inside the right front differential of my 2003 Trailblazer came apart. I tried to engage the front axle to climb a hill and when it took a strain it popped a couple of times and then no 4wd. I also had a rattling noise when I...
