Description of the problem | Several times, while driving right around 55 mph, the transmission downshifted for no reason on thruway conditions. When this happened, it was almost like slamming on the brakes quickly. On all occasions, my body lurched forward. If someone was behind me, i probably would have been rear ended. On another occasion, with my son in the truck, we stopped at a red light and the transmission clunked so violently, that we both thought we were rear ended at first. I described the issue to my gm service shop who said that they couldn't find an issue and that the codes were all normal. I was advised that the clunk at the red light was common, as the transmission has to relieve pressure. No way is this normal! I got on line to review forums and it appears this is a very prevalent issue. Yesterday, i lost my transmission completely on a thruway. I heard a loud clunk and the rpms spiked. I left the highway asap but could not go over 30 mph or the rpms would just spike without motion response. Exiting the thruway at this speed was very dangerous! Even with hazards on, drivers seldom slow down or move over, especially 18 wheelers. These transmissions are clearly a safety hazard. |
