| I have a 2002 Silverado 2500-HD 6.0 liter gas with 104,000 miles on it. The transmission shifts very smooth while accelerating, but during deceleration or braking, the vehicle starts shuttering and acts as if doesn’t want to down shift. Has anyone experienced this problem or have any ideas. Thanks. | |
| i have an 04 chevy 2500hd 6.6 that surges at idle. if i let the truck idle it jumps from 1000 to about 1500 every 4 to 5 secs. it only happens sometimes so it's kind of hard for me to pin point the cause of it. plus my engine light likes to come on an won't let me go over 2500 rpms. the code says something like (pressure regulator failure at acceleration). i know someone has to have same problem out there. if anyone can help with this please help. | |

Had a new motor and tranny replaced 14 months ago. When I take off to drive the truck, I have to push firmly on the accelerator to get it going. Once the RPMs get high enough it shifts into 3rd gear and does fine from there. It seems to be skipping 1st and 2nd gear. Transmission shop did diagnostics, said it threw a code 66. He then bypassed the computer and said the transmisssion works fine. He sent us to electric shop, for electrical problem. They checked the wiring from the ECM to the transmission and said its fine, so it must be the main computer. We have replaced the main computer and still Not working correctly. Any clues, these diagnostic fees have emptied our pocket. Please help">

| I have an 07 Chevy 1500 Silverado 4x2. 10 -15 seconds after being at a complete dead stop not moving at all or anything, my truck will clunk and surge forward almost like i was rear ended. The dealer keeps lubing my driveshaft and yolk but that is not it. It almost feels like the truck stops in 2nd gear and 15 seconds later goes "O crap i'm in 2nd and shift down to 1st." i don't know if it is a computer thing or tranny thing or what. Has anyone had this problem as well and got it fixed. I have the settle back clunk from the extended leaf springs that the lube fixes but this is way different. Please post back if you know the fix or anything that could help. | |
