So my question is if I should rebuild my transmission or just install a shift kit the transmission has 44000 original miles and the fluid is still red and does not smell burnt I was looking at pro built automatics and I want to build a trans that shifts smooth at part throttle but tire chirps at full throttle I think I should be safe just installing a shift kit and if I am can you point me in the direction of a pro built auto shift kit that will do what I stated? I have a 350 and a 700r4. Thanks in advance!
