Question about 2001 Pontiac Aztek
Most likely overdrive gear stripped.. My 01 Tek did this at 123K miles...
70MPH was equalling 3K rpm.. Dealer said was operating properly..
Transmission shop test-drove and diagnosed it easily.. Part is a splined tube with a cup on the other end.. Old part looked like someone had taken a lathe to it.
Problem blamed on a not properly hardened supply part. Expensive repair.

Governor pressure sensor or solenoid is going bad. To replace them drop the tranny pan, remove the filter , and the parts are pretty ez to get to. These aren't cheep thou, but replace them as a set. Parts will probly run about $200.

yes itcan or it may just be the solenoid for that overdrive. make sure fluid is maintained and no mounts are broken

I have that exact same truck and transmission and My Transmission did the exact same thing about a year ago and there was some kind of snap ring inside the transmission that broke. I originally thought it had to be an electirical problem because the truck shifted fine until OD or if i turned OD off. The 4r70w is a light transmission and i would suggest you have a shift kit put in and they make a heavier kit to beef it up.. Sorry its probably not the new you were looking for.

well the low cost way to go first would be to try and change the trans fluids. If the problems still remains the it may be an internal problem
