How often is the 4L80E suppose to have it fluid and filter changed ?

What works best :

Dino dex/merc ?
or
Synthetic dex/merc ?

!? OK I guese we don't maintain our trannys around here, do we cool them ?

I have a fairly good sized GM or atleast i think its a GM Trans cooler, Its alot larger then my after market 18,000GVW cooler i bought for my Ford E40D which to no avail it fried any ways. . .

So any body ever use those tranny pan coolers ? how about synthetic fluids ?
