1998 3.8L Automatic tranmission shift kit/tranny cooler question?
Been awhile since I've been on here. I have an 1998 3.8L Automatic that I have decided to beef up to a 4.2/4.3L Stroker. What shift kits if any of them is best for the 4R70W transmission? Also, what torque converter and which tranny cooler would be best?
My plans for this car is to be street legal and no more than 350hp at the crank. I am planning on 3.73 or 4.10 along with a T lock as well.
