901 transmission cooler, Can it be done on the cheap? Options

[bondo]

I have found small oil coolers with a fan for $100, but the electric pumps are expensive. My plan is to either find a cheap electric pump, or try and use the ring gear as a pump. The tricky part about the second option is it's hard to test. Can a cheap fuel pump be used to pump gear oil?

The intent here is to cool the oil and send it to the upper bearings so my 901 lasts behind a V8.

If you compare the cost of the pump, lines, fittings, cooler and the time and effort to install it against the cost of a failed transmission on a race car, then it is cheap. My setup was from Jim Patrick in Phoenix, about the normal cost for all the pieces with the advantage that everything was included that was needed in his kit. You do have to fabricate the suction fitting that goes where the drain plug goes and the spray connections into the case which means it has to be opened, drilled and tapped. If you are concerned about high temps, get Jim's VDO temp gauge adapter that goes in where the speedo drive is on the tranny and see what you are running for temps. It will probably shock you how high it gets. One BIIIIG advantage with the pump is now all I do to drain the trans is to unhook the oulet line and turn on the pump and filling the trans is just as easy, unhook the suction!
