Re: 4L60-E Mod/Upgrade Info (with Pics)
Old thread, but bumping it up.
bought and installed a Maghytec deep pan, and Parts master #678 trans cooler on my Rado. Driving the same 12 miles each way to work in the same temps (80-85*) my trans temps are 20-35* cooler. Mag pan holds 3.5 qts more than stock and the cooler is about another half a quart or so with all the lines. Bought the trans-radiator fitting (397) from Summit racing for 12 bucks shipped.
