Hello gents,
Here is a small tech tip for those of you with Porshce 930 transaxles. One complaint I have heard with the 930 is the stiff reverse detent. It becomes hard to get the gearbox into reverse when using a cable/rod shift system other than the factory's short style linkage.
Follow these steps and you will find it much easier to select the reverse gear.
1st. Locate the reverse detent plug on the passenger side of an inverted 930, if your car is so equipped. If you don't have a 930, well your in the wrong thread.
2nd. Using a 17mm wrench/socket loosen the detent plug and remove it. It is spring loaded, so please be careful not to just let it fly across the room and bury itself behind your bench.
3rd. Remove the detent plug, spring and detent plunger.
4th. Measure 12mm from the end of the spring and trim the remaining off. you should be left with roughly 84mm of spring. DO NOT cut more than 12mm off of the spring, as the detent pressure really begins to drop after that point.
5th. Assemble the detent plunger and spring and insert it back into the detent hole.
6th. Reinstall the detent cap and tighten, tourqing once to 14-18 ft. lbs.
7th. Shift comfortably into reverse instead of bracing your foot on the dash and tackling the shifter into position.
8th. Apply liberal amounts of throttle at your discretion!
