I've always questioned the need-benefit of this cooler. Just like the engine oil cooler, it has hot water circulating to it. Most transmission heat is developed in the torque converter. The Vanagon converter is self cooled due to the open housing and the air fins on the outside. I've never done any temp testing on these as they cause so little trouble. For what the parts cost, I also see little reason to play with installing used auto sections from junk yards. It would be a nice upgrade to use an Audi 5000 transmission but unfortunately, it turns the wrong way. As for shift speeds, it is extremely important that the accelerator cable and throttle linkage is adjusted correctly. When pushing the accelerator down, it should get hard ~1/2" from the floor and then finish traveling. This is the kick down mode. In this position the throttle will be wide open that that spring on the linkage should be depressed. In this position, the transmission should up-shift at ~5200 rpm. If not, then there is a problem n the valve body or governor. Dennis

Is the Tranny OK with that in a Vanagon? My tranny is toasted and has not been right since I got the van. That said, I feel like it shifts way too soon. It will be in 3rd by 25mph under fairly normal driving. I have no tach either, but it just feels like it is almost lugging the engine. The engines in the Golfs and Jettas are more high revving, so I could see them set to shift at higher rpms. Edward At 08:10 PM 3/9/2003, you wrote: > > > > gives a real nice description.
