I wonder what would be an easy and/or effective way to do this.

Does aluminum transmit heat well? Given that most of our transmission/transaxle cases are AL, this may be an issue.

Related to this: heating the transmission would be less of an issue if the lube was lightweight and 100% synth (its viscosity was more stable). Currently I'm running GM's semi-synth. With a weight that's similar to 5w30. Any recommendations on a fully synth, lightweight lube?
