It's a new RBT ZF. Originals used a mechanical drive pump. But don't know if an aftermarket electric is only option. I'm assuming I'm going to have to drill/tap holes in transaxle. I just can't find info on available period correct pumps.
My five cents worth is don’t worry about a trans cooler unless you’re going to be racing. Fit an engine cooler and oil temp gauge. Modern engine oils are safe to about 130degC so it’s sometimes questionable whether normal road use needs an oil cooler except when water cooling is a problem. If that’s unstable then you’ll find excess heat dumping in the oil!
