Transmission started slipping causing a "shudder" around 55 mph or lower if I am hauling something. We took in to dealer who said the torque converter clutch is bad and they can replace it or put in a whole new transmission at a cost to us of $3,300. After searching online I found TSB #050730017 which outlines this known problem. I have several friends who have had this same problem. If this many people are having this problem and it is know by gm I feel it should be handled by them. The technician that handled our repair said that the tranny fluid should be changed every 25-30k miles since we live in a mountainous area and occasionally pull a small horse trailer. The manual states that it should be changed every 50k miles with no reference to terrain. I feel that gm should cover the cost of this repair since they know about the problem and have done nothing to notify owners of the issue or how to correct it.

Vehicle torque converter slips / disengages on inclines causing the vehicle to roll backwards after trying to proceed after a stop. Must be on the gas simultaneously with coming off the brake to prevent rolling backwards into cars or people. Happens in drive, third and first. Transmission locks in second. Torque converter also slips while at idle in gear causing a rough idle situation.

Car is rolling backwards when proceeding after being stopped on an incline.
After numerous other repairs to this vehicle, it started whining through the first few gear changes. The gm shop said that the torque converter went out and they had to overhaul the transmission. It is still in the shop because after they put everything back together, the whining noise is still there. After 11 days and three tear downs and rebuilds, the mechanic is at a loss as to what is wrong.

The torque converter clutch relay in the transmission overheated, causing excessive pressure, which caused the transmission fluid to push the dip stick up out of the dipstick tube. Then the transmission fluid escaped. Traveling down the undercarriage of the vehicle, the transmission fluid hit the exhaust manifold and ignited into a flame that burned along the undercarriage of the vehicle (including the steel plate under the gas tank) and extended two feet beyond the rear of the vehicle. We were forced to evacuate ourselves and our four children from the vehicle along side the highway. Four other vehicles were forced off the road as white smoke hindered their field of vision. The mil indicator (I. E. , check engine light ) had a code of p1870 (transmission slipping). This code has been associated with hundreds of torque converter clutch relay failures in gm/chevy full-size pick-ups, Suburbans, and tahoes (discovered by searching for "p1870" on the internet and queries at the NHTSA website). Technicians have determined that the tcc relay is undersized and tends to overheat causing major transmission damage (in my case, a full transmission re-build was required - $2000 plus towing and rental car). Technicians say that there is an aftermarket tcc relay made by sonnax that, when installed, prevents this problem from occurring. This is a serious safety issue (just look at the black charring on the bottom of my gas tank shield) that caused great peril to my wife, four children, and myself. Gm needs to be held accountable to correct this potentially fatal failure.

Vehicle experiences grinding/rumbling while in highend torque situations (I. E. Going up slight grades not steep enough to cause downshift). Stops when I bump accelerator. Replaced u-joints, but did not fix. Was told by gm tech it was probably torque convertor failing.
Our chevy Suburban has just over 50,000 miles and is past the warranty mileage. On a trip to las vegas, the truck started to jerk fiercly into gear. When I accelerated, the truck would jerk into gear. The transmission specialist that did the repairs advised us that the torque converter had gone out, and shrap metal was getting into the transmission fluid. This happened in a matter of 1 day. The technician also advised us that he had performed the same repairs on 3 other chevy Suburbans that day alone. We were told that this was not caused by "normal wear and tear" and that this should not be happening to a truck with only 50,000 miles. I took the truck in to get the tires balanced, and was told that the front brakes needed to be replaced. When the technician was beginning to remove the brake pads- he noticed that there were cracks in the rotors. We were advised that the cracks were heat cracks, and that we would need to purchase new rotors. Once again, we were told that this was not caused by"normal wear and tear".
