I use to love this truck, but for the past 6 weeks it's been to 4 chevy dealers and now another garage. I have serviced the transmission 2 weeks ago replaced the transfer case,put new wires and plugs, replaced fuel injectors and fuel pump and replaced fan clutch for the a/c and it is now make a really loud noise. garage says it is either the transmission or the torque converter. I can't take much more. Any thoughts.

 

Well I guess I'd start by taking it back to the dealer that did the transmissionservice and find out exactly what they did to the trans. You said they serviced it but to what extent? Did they just do a fluid change? (Partial or full? Did they change the filter? Did they adjust the bands? Anything could have happened. How many miles are on the Truck and how often was it serviced? Did you buy the truck new or used? If used, the previous owner could have just beat the snot out of it...There are just too many variables to give you a real solid answer. Sorry.

 

I bought it new. Have maintained the service schedule and had the a full flush of the transmission 2 weeks ago when the crank case was replaced. The garage it is at now can find nothing wrong with the transmission or the torque converter, but it is still making noise at 40 and under. I think I will attempt to pick it up, haul home the trailer and trade it in!!

 

Hello. I have a 2001 Chevrolet Silverado 2500 Diesel.
I need to know why my truck slows down when I accelerate more than 50 miles per hour. It's like the computer knocks down and stays at 25 miles per hour. I don't know if it's the pressure sensor that not receive the signal or the diesel pump is not drawing the correct pressure.
