Question about 2008 GMC Sierra 2500HD 2WD

1 Answer

Delay throttle response. Shifts to early

I have owned 3 2500 HD trucks. 2000 GMC, 2002 Chevy and now a 2008 GMC. It is a company truck so I didn't pick it out. It seems to me that the throttle response time is very delayed and that it shifts into lower gears far to early. It has been to 3 different dealers and they all say its fine. One said that it had to low of a gear in it. Does anyone have a suggestion in rear end gears? Any performance suggestions? Air Filter etc. Other than that the truck is solid and tows well. Its the reg driving that aggravating.

Changing out your rear end gears is not the solution to your problem. If you are unhappy with the way your automatic transmission shifts, your mechanic should be able to adjust the computer that controls it to shift differently through all the gears. If your problem is when you launch the vehicle from a stop, you should consider having the idle raised a little, that should fix your problem.

How can I adjust the parking brake on my 2002 GMC Sierra HD


Umm... I could be wrong but... the 2002 GMC 2500 has rear *disc brakes with an interior set of *drum brakes for the E brakes. check with your dealer because there was a recall on the E brake for some early 2000 GMC trucks. also there is a manuel adjuster for the parking brakes.

I had an 89 Chevy Silverado with a high idle problem, A lot of money later and a lawsuit against a repair shop that said they fixed it and they didn't caused early engine failure and they wind up paying for a new engine. Long story short, I found out the main cause was I had to replace the throttle body gasket because it was bad causing more air intake and the on board computer tried to compensate for the air by adding more fuel therefore, high idle. I hope this helped.

My 2002 Chevy Malibu sometimes shifts very slow. I will go from park to drive and there is about a 3 second delay.


I would first check the fluid level. If it is a little low it could cause the slow shift. I would also recommend putting in a can of TRANS X. It will clean up the valves inside of the tranny. I did this with my 2001 malibu and never had trouble again. I have 290,000 miles on it!

When trans. is warm after extended driving the up shifts are very hard. This only happens during extended driving periods. Around town everything shifts fine.


Shift suddenly become very hard. When going from park to either reverse or drive it slams into gear. 1-2 and 2-3 shifts are also harsh. All gears seems to work. Problem may be intermittent: Check Throttle Position Sensor (TPS) for smooth electrical response. If the response is jumpy or erratic at all, replace TPS. Good luck Auto Zone or Parts Source has this part and can be replaced with in 20 min. Both parts store will have the step by step instructions and i believe the cost is around $65.00 for the TPS which is better then a transmission replacement.

This is the downfall of a new toyota congrads you can relate to me i Own a 2008 Scion tC these new toyota's are driven by what is called "Drive By Wire Throttle system" there will always be a delay in the throttle response espcially in newer toyota's with an automatic transmission hence the newer ones have a 5 speed automatic transmission instead of the 4 speed automatics kind of a poor design on there end with the Drive By Wire. Sorry this is a problem that happens to be a design flaw on toyota's and some people notice it more than others.

If your 2002 gmc envoy or sierra will not even turn over with a kown good battery try starting it in nuetral then go back to park and try starting again. There is a park nuetral safety switch that can malfunction. Turn the key on then shift into nuetral, then turn fully to start.
