That's a good answer to the original question..

One of the trade-offs you must deal with to have the convenience of an auto shift Vanagon is that in the mountains or on some more technical driving surfaces you will be stuck with it's designed-in shifting parameters. You will trade away the ability to anticipate an upcoming terrain change and to modulate how the power is applied (the clutch) to the wheels. However, if most of the driving you do is low angle freeway and city traffic..it's a worthwhile trade off, to some. With my inline four 1.8 liiter (only slightly more powerful than a WBX with the power coming at a much higher rpm range) I'd probably hate a VW auto tranny. I can see the Bostig/Zetec motor not working too well with one either. Someone mentioned driving with the Big Rigs uphill. I imagine that a Vanagon with a real Gear-jammer type multi-gear transmission, like the big tractor trailer rigs all have would be more easily kept at speed...We probably have a similar HP/Torque to Weight ratio as a loaded semi and they need every gear they have to keep on truckin up those passes...Imagine a semi with only a 3 speed auto tranny...
