I have a 1997 Tahoe 4wd W/automatic transmission. I have just had a problem I hope someone can help me out with. After driving at highway speeds 65-70 for about 25 miles as I slowed then stopped the ABS warning light came on and it seemed like the transmission was disengaged or slipping. I put in neutral then back into drive, nothing. I slipped it down into 3rd, nothing.
When I put into 2nd it ran and I was able to go the ½ mile home. After sitting awhile it seems OK and moves in reverse and in drive, and the ABS warning light is gone. What gives? Is this a break issue causing the computer to disengage the transmission to or is it a transmission problem giving an ABS warning light? Where do I start? Thanks for any help you may offer. Doug
Answer: These problems could be either way. ABS causing trans or vice versa, or neither. You may have a power feed problem. This would cause transmission and anti lock brakes problems. First is to get the ABS computer scanned for codes, as well as the Powertrain computer(PCM) for any trans codes. If loosing power to the transmission solenoids, this would give your condition. Same for the ABS. You may also have a valve body problem inside the transmission.
Tahoe Transmission Hot Light
What does transmission hot light mean on a 2003 Chevy Tahoe?
Answer: the transmission hot light means just what is says, the transmission is getting too hot. More technically- the fluid is getting hot. Sort of like an engine overheating. High fluid temperature is a sign that the transmission is slipping since slipping causes friction and friction causes heat. Take you truck to a shop and them check the temperature after it has been driven a while. They will determine if the transmission is getting too hot, or the sensor has gone bad.
