replacing the transaxle - fluid issues

[lee]

Anybody want to offer their opinion of how I should go about fluid/filter changes when putting in a junkyard transaxle?

The new (to me) transaxle has 29k miles on it. I have been thinking I would drop the pan, put in a new internal filter, run some cheap (super tech?) dino fluid in it, maybe with some Auto-Rx, for a few miles, then pull the pan again, internal filter check/change, change my external filter, then go to a synthetic. Also thinking of moving the cooler from between the condensor/radiator to the up front position - think it's worth the trouble.

suggestions/alternatives???
