Transmission Cooler

Wait.... does your current radiator have a trans cooler?
(Manual transmission car radiators didn’t have provisions for transmission lines.)
If you have provisions in the current radiator for coolant lines, just tap the “Out” side and run it to the aux. cooler and then back into the return line.

If you don’t have provisions for transmission cooler lines, use factory lines as far as they go and then connect them to the cooler with flexable hose.

Mount that cooler in front of the radiator. Where ever there is a clear shot to provide a breeze or wind. The question of if it enough can be (or should be) answerable by B&M’s rating system for that model or one as close as possible to it by way of how many cubic inches the height and width are.
