Hi, not sure if anyone has ever gone though this problem before. My 98 SSEi w/161,000 hunts for gears around corners going about yeild speed. It also does the same thing if I come to a yeild sign quick and axcell fast after it, the tranny will act like it is stuck in torc lock up mode or it is just plain stupid , it doesn't know which gear to go in unless I give it a kick in the butt with the gas then it will finally downshift to 1st around corners or after yeild sign. Had it to 2 difrent transmission shops and theres is no codes, level is fine as well as with the fluid. One of the techs thought it was the PCS because the pressure drops very low when the tranny acts up so I had them replace it but this 395.00 repair did not work. Please get back to me on this. Oh yah, this has been going on since about it had 120,000 on it. Toddster.

Are you sure it'* gear hunting, or might the motor be hesitating?
wrong section BTW, should be in 1992-1999 rather than 1987-1991. No biggie though, a staffer will move it shortly

Ok..There was a thread recently in 92-99 about fluid level in trannies.
GM gives us a dipstick and tells us that is the correct level. This is what I go by and will continue to use.
However a few mentioned if you turn a specific way the fluid gets hammered to one side causing a low level..aka low pressure situation. I believe it was a 1/2 quart that was suggested.
Please understand I am providing something that was already discussed, not suggesting you to overfill your transmission. My suggestion would be to search out the thread. I believe if you look up "half quart" with author Rogue you will find it.

From Rogue'* write up: (I always put 1/2 quart EXTRA into the trans when filling. The 4t65E has a fluid starvation defect where its possible on a hard left turn for the trans not to have enough fluid where it needs to be. An extra 1/2 quart helps take care of this.)
This sounds logical but mine hunts for gears around all corners left right and going straight from a quick stop. -Toddster :?:

This is a touchy subject...
The 65-E is a highly computer controled tranny....
There are various inputs that have to be correct... There is a force motor of sorts that controls line pressure, but ultimately the PCM controls the pressure and the shift points, TCC apply, and shift quality...
With the milage on your car its not all that impossible that the trans is showing signs of age...
When the tech had the car hooked to the scantool he saw no codes...?
Did he take the car for a real world drive to see what the problem may be, with the scantool in hand( usually a good snap on )?
You may need to take it to another tranny shop... They are not all equal... There are some out there that do know a lot about the GM FWD transmissions...
Good Luck
