2005 Chevy Trailblazer transmission problem. I have a 2005 Chevy Trailblazer with 145,000 miles on it. I am having a strange transmission problem that I would like some opinions on. When the vehicle is started first thing in the day, one can drive for 4-5 miles with no problems and then the transmission disengages itself and then engine races (like one shifted into neutral while one was driving.) If I pull off the road, put the vehicle into park and shut off the engine and wait a minute or two, I can restart the engine and drive normally for another quarter of a mile and it does it again. I can do this process repeatedly. No codes show on the dash. Fluid levels are good – fluid changed at 100,000 miles. Fluid is slightly dirty but not burned. When transmission is engaged and running, the gears shift normally and there are no transmission noises. When the “neutral” condition occurs, I can shift into any of the forward drive gears, but the transmission does not respond. I have to physically shut off the engine and restart it before I get the gears back for a short distance. Any thoughts or suggestions or things to look at would be greatly appreciated!
I have a 2003 2500HD with the 6.6L LB7 duramax. It is currently 19F here in ohio and after plugging in the block heater for about 4 hours i started my truck. Engine temp was below 160, everything was running fine, but the check engine light was on, trans temp gauge was pegged aover 300F, and a message was on my dash that said TRANS HOT IDLE ENGINE. I let it idle for a while and it never cooled down. Drove it to the end of my apartment complex parking lot and it wouldnt shift out of first gear. Went back, parked it as it was time for me to go to work. Rarely use block heater. First time i used it since beginning of 2019. The next day(today) I went out to run diagnostics and to see what codes where being thrown. Started truck to see if trans temp was still pegged and the gauge went all the way up to red, then down to 160, then up to just below the red with no TRANS HOT MESSAGE. Drove it to gas station and it shifted hard. While idling at gas station for 5 mins the trans temp climbed into red, TRANS HOT message came across the dash and i limped it home in first gear(maybe quarter mile). Codes - P0380, P0700, P1621. Cleared codes and check engine light was still on. Could the block heater have anything to do with this at all? Maybe a malfunction from a short or something? Fluid is full, doesnt smell bad or seem burnt but i noticed a funny smell when walking away(maybe just paranoid) Please......help.
I have a 2009 gmc sierra 1500 5.3l 4x4 with 54 thousand miles and recently it seems and feels like I've been having transmission and or torque converter problems. When I'm almost to a complete stop it feels like something just locks up and I can even let my foot off the brake pedal and not go anywhere until I press the gas pedal and start kinda moving, then it feels like something releases. Any advice or help would be greatly appreciated.
