I just finished a swap in the other direction; replaced an aircooled
tranny with a waterboxer unit.  The aircooled transmission is only
better if the slightly higher ring/pinion gearing (4.57 vs 4.86) is
important to you.  In many other aspects, like gear strength, smooth
shifting, and availability of repair parts, I think the later
waterboxer trannies are superior.

What is the difference between my 2.1 and the aircooled transmission. I may have a chance to pick one up for future use and just wondering if it would be worth it.
