What Fluid do you reccomend? Turbo 350, back halved car 2900 lbs
8 inch convetor , foot brake, I did hundreds of runs in this car last year.

What kind of fluid do you reccomend? what is the basic fill up( i gallon 2) I know this will vary with the big trans cooler but looking for a starting point.
Thanks
