I am throwing this out there to see how everyone feels. Possibly a rule change?
The cost of transmissions, and repairing them has become very high.
After looking into manual transmission failures, the main contributing factor is HEAT! @ +250° The oil started to break down. The aluminum case growth is faster then the counter and main shaft. Which puts a tremendous load on the gears and synchronizer.

So I am proposing adding an external oil cooler to ours transmissions. No transmissions modification, strictly bolt on.using existing holes in the transmissions.
Something like this,

So thoughts? Comments?
