If your talking about a vig. 2800, definately get a cooler, for me the tranny held up the whole time i had the converter in and still is(knock on wood). Once you put a set of slicks and bring it to the track, start saving for an Eaton posi unit. No less than .4-.5 on your e.t.

 

Anyone running one of those e-fan tranny coolers?

I'm considering getting a small fan for my stock cooler and wiring it up with my main e-fans. Or maybe just toggling it from the dash.
