94 SL2 Auto Transmission - Shifts Hard into Reverse
I've been having a problem with my auto transmission for quite some time. Often when I go to shift into reverse, it doesn't shift right away. Sometimes when it just isn't shifting, if I give it a little gas, it'll then shift really hard into reverse. Really a pain.

I recently changed my transmission fluid and now I hear a noise ( not high like a whistle but it seems to fluctuate with the RPMs of the engine). Also now it will sometimes shift a little sloppy into 2nd...kind of like a double pump kind of feeling if that makes any sense. I never noticed either of these problems before changing the fluid. I thought maybe I didn't add enough fluid but I added what the manual said.

Any ideas?

The fluid level is checked by the marks on the dipstick. Not by how much you put in. Make sure that the fluid level is correct. Engine and trans at normal operating temp and check on a level surface.

Added 1/2 Qt of fluid and haven't heard the noise or felt any shifting sluggishness this morning. Seems like it will be ok. Thanks!

Still have the first issue. Any idea why my transmission hesitates so long before it decides to clunk into reverse? Like I said sometimes it just sits there until I give it some gas.

Appreciate your help.

One possability is that it's damaged. Note - be consistantly patient for it to shift into reverse before you rev. I lost the tranny on my old Corsica that way - got into a tight spot while driving, threw it in reverse and waited the usual time for it to shift, then pushed fairly hard on the gas. The tranny hesitated longer than usual before shifting. The engine rev'd up high, then THUNK! All I had left was 1st gear, which drove it to the junkyard to die.

Here for the reverse slam cure

I have posted this proceedure to cure the reverse "slam" in other ( to remain unmentioned) Saturn forums. This sounds weird, but has worked in nearly every Saturn I have tried it on. Don't go cheap on the fluid or filter...and follow the steps EXACTLY.
1. Change transaxle fluid (Non-synthetic) and filter (Saturn part ONLY please)
2. Add your choice of transaxle fluid additive (IE: Transmedic- Personal preferance Prolong transmission and gearbox additive)
3.Back the car up against a SOLID nondamaging object or wall and/or FIRMLY set the parking brake and chock the wheels.
4. Start the car and place it in reverse and LEAVE it there RUNNING in REVERSE for approx. 30 minutes.

THis will NOT harm the transaxle. What it does is simulate driving the car in reverse for like 25 miles..using the clean transaxle fluid and additive to clean and flushout the reverse gear switching valve and valve body passeges. I know it sounds/seems weird but it works like a charm 95% of the time.

Used from Wolfman!

get used to it gonna go out and your gonna have to push it back. "done it" lost 2nd gear.... balh blah don't care the tranny will die!

So if I understand correctly, I put in some tranny treatment (I just changed the fluid and filter a few weeks ago) and I let it idle in reverse for about 30 minutes while the car is up against a brick wall. Correct?

that is correct and it should correct the reverse slam problem
