The AT has a pump which pushes ATF around. This pressurized ATF moves pistons which make the AT do its thing when it's time to shift. Like our engines, there is a pickup tube in the sump which draws in this ATF, and that pickup tube needs to always be fully submerged below the ATF fluid level. If the ATF level drops below the pickup tube, even momentarily, the pump will suck air and the shift will hesitate. It's important that the ATF level be high enough. The level must be checked with the engine RUNNING. When the engine ie running, the ATF pump is also running and all the fluid passages are filled. This means that the sump will be at its normal level, which is lower than when the engine is off and all the ATF has drained back down into the sump. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
