I've never heard of a manual trans with an oil pump to force lube the gears and bearings etc.
The manual gearbox that Rover used for the SD1 model was lubricated with TQF (auto trans fluid) and this was pumped around the box with a pump driven from the input shaft.
I don't personally know of an other example, but there probably are are others.
The issue of rating a car for towing is a legal one, and not something I know much about. However, none of the Ford Ka models are so rated and my belief is it's a structural/tow bar mounting issue and nothing to do with any lf the engines or gearboxes that might be fitted.
There are issues applying to trailed weights but most folk reading this have B+E on their licence so don't care. Youngsters will though.
