installed FLT level IV tranny with sonnax servos
#1
feels great. nice and tight shifts. downshifts faster, and i dont have any worry about breaking it, as i did while driving teh stock tranny. everytime i floored it with the stock tranny, i always thought about this being the time it breaks.
customer service was A+. even a couple months ago i was asking questions not even planning on buying a transmission. these guys are greats.
thanks chuck and vince.
