Found transmission shift smoother. install is not as simple as you might think took about 4 hours need to rip out the valve body and split it apart to install new parts. Do some reasearch before attempt my buddy works at allison he gave me a hand need to be careful with the plate you drill in between the valve body very fragile because that is your seal for the oil passages if it you damage it, it will cause problems in pressure Be careful! but good product! i have it on ppe level 4 in lbz so far so good!
finally i can hold my big tune
