Chevrolet Colorado

"Rough shifting into neutral when coming to a stop."

"The rough shifting has happened only once that I recall and has not been an issue in the past 8,000 miles."

"There was a problem with the 8 speed automatic transmission, that GM said was caused by the fluid that was originally used. The original fluid was hygroscopic and a new fluid was developed. The transmission was flushed and refilled with the new and improved fluid. I am cautiously testing this “fix” for the next few hundred miles. The symptoms were a shudder/vibration at certain speeds that is covered in GM Bulletin #16-NA-175."

"At 2000 miles developed a torque converter vibration,was repaired wit a fluid flush,shortly after that developed a very rough shift when cold,dealer has not been able to repair problem contacted gm and they were no help at all and no support"

"TSB-Chevrolet changed the transmission fluid to a different type."

"Apparently these have had a shutter in the transmission which a fluid change helped a little. But still have some issues"

"When cold, the upshift thru lower gears is rough."

"Was slipping when at certain speeds. Corrected by dealer changing the transmission fluid"

"After about 12 month the transmission started slipping a bit around the 55mph +-5 mph. It started getting worse around the 14 month range and I finally contacted CHEVROLET at the 18 months. CHEVROLET was aware of the potential problem but did not considered it necessary to do a Recall on the trucks. The dealer changed the Transmission fluid because CHEVROLET said that the original was hydroscopic and absorbed water from atmosphere. New fluid eliminated the problem. CHEVROLET said that if it ever came back then the torque Converter will be changed. There was no cost to me for the process."

"The lines from transmission to cooler leaked. As there is no sensor for fluid level, and no dipstick, I didn't realize it until the transmission stopped working -- 1000 miles from home, of course -- although it apparently was not damaged. As this problem is not common, parts had to be shipped from Michigan to California. Later, a transmission seal was found to be leaking."

"The lines to the transmission cooler leaked when the vehicle was new, although I didn't realize it at the time. Since that was repaired, every time I have the oil changed I have them check for a new leak, and every time they find one. Four different seals or gaskets have been replaced so far, and it might have another leak now."

"Widespread problem referred to as transmission shuddering by GM. The problem occurred with my truck at only 1400 miles. Current fix is a thorough transmission flush and refill with improved transmission fluid. I just got my truck back this very day, but cannot confirm that the latest TSB prescribed fix has worked. The transmission ECM was also re-flashed, hence has to learn all over again."

"Truck had vibration under mild acceleration between 40-60mph. Dealer replaced the convertor and the problem went away."

"Noticed slight vibration during first 5,000 miles that was unbearable at 6,000 miles. The vibration was like running over rumble strips. Took it to the dealer and they replaced the torque converter. No problems since."

"Torque converter cause strong vibration. It was replaced and same problem occurred. This time they put a different fluid in to it and it is OK now."

"I was told vibration was caused by the torque converter and that the fluid flush and by using a different fluid would correct the problem,it did take care of the vibration but now have a very hard shut of slipping problem when cold"

"It shifted up and down randomly. The dealer fixed it. It was still under warranty."

"Transmission went out. Had to be replaced"

"Front end suspension. Wrong size bolt was used."
