speedbump

I didn't put too many miles on it after t he oil change. My brother in law now owns the truck so time will tell. All I know is what the dealer told me, but whatever they did, the shudder is gone.

I had my torque converter changed early on with my 2015 Denali. Then an oil change ar around 55,000 and that fixed it the second time. They found out it wasn't the converter, it was the oil they were using. Makes no sense to me, but the oil change fixed the shutters.

I had a truck that would quit then start up and go. Turned out to be a wire on the fuel pump that wasn't plugged onto the spade connector. It was just laying against it. Hit a bunp, it would fall away then reconnect.

I found leaving half of the nozzle out of the filler does help.

Stick with the new converter at least. That's what fixed mine!

OK, no local. That's probably a good idea anyhow, everybody has given good marks on Black Bear. I'll give it a go.

OK guys, your getting me excited. The truck is a year old and I just had the new torque inverter installed because of the studder when trying to downshift thingie going on. I am not pleased with the way the truck shifts now and never have been, so that improvement would be great by itself. I don't know if there is a tune guy in my area but I'm going to find out. No matter what I end up doing, I will come back and tell y'all about it. One more quick question, is the Wife going to like the truck better after the tune, because she drives it now and then.

Thanks for the info, I'll check it out.

What kind of performance enhancements can be expected from a tune? I tuned my old 2001 Sierra C-3 with a 6.0 liter engine and didn't see much difference except in shift points.
