SATURN SL1 CLUTCH PROBLEM

2001 Saturn SL1 • 192,000 miles

Okay I have a trans issue. I replace it with another one and it seem to have the same issues as the one I took out it has a delay when you put into reverse for and 5 seconds and then when you are driving it it shift kinda hard out of third and really hard out of fourth into overdrive I also did notice a shutter noise when it goes into second. I get a pending code of p0732 I have add the lucus stop slip in it but if does not seem to do any thing for it. The trans I got from a junk yard and have contact them them told them they gave me a bad transmission they told me that the car it came out of was test driven before they sent it to me and it shifted fine for them. So I am at a lose on what is wrong. Please help

So the when you air up the 2nd clutch pack port the clutches wont move till you put pressure on the clutches themselves?2nd gear is the larger of the two clutch packs that are back to back.

Um when I put air to the port for the 2nd apply piston it moves and stays out it is not like the 3rd apply piston where it goes back and forth it the 2nd clutches are the ones facing the drives side wheel and the 3rd are facing the other way on the same shaft. The 2nd clutches seem to move better when I put my finger on the other than that they do move on there own just slower by the way there does not seem to be any leaks that I can see or hear but I don't know what I should be looking for. This is my first time doing this kinda thing.

Iam in southern California you can pouring some transmission fluid over the clutch housings and look for. Bubbles I have used that method to find leaks before. Another thing that happens to those transmissions is the input shaft that the 1st 2nd and 3rd gear are on the nut that goes againist the 1st gear clutch pack under the side cover loosens up.I have seen them loose up so much you loose reverse all together. Also to where the first gear clutch pack eats into the side cover. But you said as soon as you shift into reverse the pressure shoots to over 200 psi even though there is a 5 second delay into reverse?

Yes it shoot over 200 then it drops for 5 sec. Then it shoot back over 200 so do you think I should check the nut and see if it is torque to 150ft? Or is it 115 ft?

It shouldnt drop pressure like that when in reverse it should go toover 200 and stay there the pressure is going somewhere.I always torque the nut the nut to 115 ftlbs. If the nut is loose then remove the nut and add loctite then torque it down. Also when air checking 2nd and 3rd gear does the shaft move a lot?

Okay so I took off the side cover and grabbed the 1 set of clutches and there is play in the shaft of course I did not have the 23 mm socket to see if it was loose but just to be safe I will remove the nut and add loc-tight and torque it to 115ft lb. And i'll torque the other nut too seem how I have the cover off. When I air checked it I did not see or feel the shaft move

If the clutch pack has looseness on the shaft then the nuts loose you will need a thin wall socket probably a 3/8" drive one. Also when putting the side cover back on there is a trick so dont damage the seals and tubes. Before putting the side cover back on look down into the shafts and see if the bushings in them are in good shape. Now when installing the side put the transmission in drive. But be careful not to jamb or bend the rod going to the manual valve of the valve body since its not hooked up with the valve body off. Then while inserting the tubes in shafts and installing the side cover turn the left front wheel hub as you slide the cover on. That way the cover will slide right on otherwise you will probably fight the cover and damage something.

Okay I torque the two nuts and put it all back together and now it wont go into reverse what did I do wrong?
