This GoWesty-designed plug replaces the original internal hex gear oil fill plug in your transaxle with a 19mm external hex plug. This allows for easy removal of the gear oil fill plug without a special internal hex tool. Finally! It also features a 1/8" NPT port, so you can easily add a temperature sender to keep an eye on the temperature of your transaxle.
Fits: All 1968-91 Type II Bus and Vanagon manual AND automatic transaxles.
