Transmission help

I need to know any code's you might have?Did you replace the valve body or was it replaced before you got the car?Also if you replaced it where did you get the replacement valve body?I need to know how it shift's does it shift hard?Does it flare or slip before shifting?Does it late shift?Or not shift into some gear's?Do you have a delay or no reverse when it get's hot?The more info on the shifting the better paint me a picture since I can't test drive it to see for myself. The input shaft nut hold's the first gear clutch pack in place and keep's the input shaft from moving too much from side to side. The earlier saturn's the input shaft nut's don't usually loosen up they do but not that often. The later one's do more often. When they do loosen up you will get a delay in reverse or if they get loose enough no reverse. But a bad valve body can cause that and bad shifting. Just because the valve body was replaced doesn't mean we can rule out a bad valve body.I have replaced valve body's even with a factory saturn valve body and gotten a bad one.I just replaced a valve on 1995 saturn SL1 and two week's later bad valve body again. Let me know the answer's to my question's and I can help you.I'm a factory trained saturn tech I really know these transmission's.

Ok so we have a hard shift and when you put it in reverse it goes into it with a second or two?If the nut was loose enough to cause a shifting issue then you would have a delay in reverse.I have never seen a bad valve body cause the input shaft nut to loosen up.I have also never seen a loose input shaft nut cause a hard shift into all the gear's. When the nut loosens up you loose pressure and fluid bypasses seal's.A hard shift in every gear would most likely be caused by too high of pressure not too low. If the pressure was too low the transmission would slip when in the different gears and have a delay into reverse. Reverse requires full line pressure to engage correctly. In your hood fuse box there is a fuse labeled
TRS LP see if that fuse is blown. Also do you have any code's that would really help if you had any and I knew what they were. Do you know how to check for code's?Also that valve body they put on could have been bad right out the box I have seen that happen. Without checking the pressure's you would never know. Let me know what you find.

Give what I posted a try to see if you have any code's if you do let me know what you find.
