Wolfman's Reverse Slam Remedy

[RC1488]

NOTE: This proceedure "can" often cure a delayed engagement or reverse (reverse slam) in Saturn autotransaxles PROVIDED you have not waited "too long"

DO NOT MAKE UP YOUR "OWN VERSION" follow the instructions exactly...

The "works nearly everytime" cure for the reverse "slam"

1. Change the transaxle fluid and filter (use "conventional" not synthetic fluid)
2. Add your choice of automatic transmission fluid additive (transmedic, Lucas etc...personal choice, Prolong auto transmission additive)
3. Start the car firmly set the parking brake, chock the wheels and or back it up against a firm immovable object (A brick wall works well)
4. Put the car in REVERSE and LEAVE IT THERE, RUNNING, IN REVERSE, for about 20-30 mins at idle.

What this does is use the clean transaxle fluid and additive to flush out the reverse passage in the valve body by simulating driving in reverse for about 10 miles. IT WILL NOT HARM THE TRANSAXLE OR ENGINE IN ANY WAY. After completing this proceedure, (99 times out of 100) your reverse slam will vanish for at least several months and maybe forever (actually usually forever is a better description) Maintain the transaxle correctly from that point forward. If it initially does not work for long, you can REPEAT the proceedure without changing the clean fluid and sometimes net good results BUT if after 2 tries things have not improved you are probably looking at valve body replacement. YOU MUST CHANGE THE FLUID FIRST! Doing this with "dirty" fluid still in the transaxle may actually make it WORSE. Also "normal" transmissiopn "flushes" WILL NOT cure this problem, as they don't feed enough "warm" clean fluid through the valve body for long enough.

No or very delayed REVERSE with NO PROBLEMS with ANY OTHER GEAR = VALVE BODY ISSUE only 99% of the time

No or very delayed REVERSE WITH PROBLEMS with other FORWARD GEARS (especially 2nd) = LOOSE INPUT SHAFT NUT 99% of the time.
