Power Issue, Bad Wires, or Trans Issue..........Plz Help !!!
Just want to get some opinions on this problem I am having ever since I hit at deer back in June of 2006.
Acceleration from 0 - 40 seems good. Problem only exsists when truck is at FULL operation temp, but right after 40 mph, the truck loses all power, I know the Torque Convertor kicks in right at that time, but every other Chevy I drive as soon as you touch the accelerator the TC unlocks and you have full power again. With my 99 Silverado, it takes almost a 3/4 accelerator push to get the TC to unlock. So with a nice gentle accel, once you hit forty, to keep a decent accel, you have to push 3/4 throttle to get it to kick down a gear / unlock TC. Is this a problem with the TC or is a wiring problem. Also, where else could the problem lie ? They have done reprogramming of the PCM and put in a Pressure Cellinoid, Knock Sensors, and Intake Gasket that was cracked.
Any ideas would be greatly appreciated
..... I do have aftermarket 3" exhaust which did come into play with a GM dealer, saying that it was throwing my rear O2 sensor off causing the problem, any truth to that idea ?
Hi Bubba ... I can't help but think there's a TC problem, but you failed to mention what kind of repairs were. Whatever it is it's seems to be systemic and you will need a dealer to go through it. If you don't like what you are getting from one, try another. And remember if it can be linked back directly to the deep hit you may be able to file a supplemental claim on your insurance for the repair. You may also want to talk to a public adjuster to help you determine, given the ongoing issues (if they can't be solved) if there's a chance to reopen the case and total the truck. Good luck!
