All of the research I could find is in this thread. Sadly, there is nothing saying 'heated oil shows a X% increase vs cold oil'. All I know is it will help. To what degree will need to be tested. Only after can we say it is or isn't worth it.
Its a fun experiment.
Some of us are here to save money, some are here to save the environment, some of us are here to have fun and tinker. I'm a fan of all of those.

Yeah, that would really be ideal. I kind of doubt there is room inside. We'll see when I start taking things apart though. Any ideas on what I could put in there if there is room?
My current thought is to glue (yes glue) a fabricated pan to the transmission housing. The pan will be formed to the outer shape of the housing thus conforming to all its irregularities and maximizing the usable surface area (vs a flat block as previously suggested). This should allow quite a bit of heating surface area. Inside the fabricated pan will be a serpentine path for the coolant to flow. There will be an inlet and outlet on each end of the path for coolant connections. Locktite makes some epoxy for bonding metals that will easily hold up to the temperatures seen. JBweld might also work just fine too.
