Update - So I test drove the car today after installing the TF-2 kit and I'm somewhat disappointed. The WOT 2-3 shift is much improved and occurs about 4500 as apposed to about 3300 but the 1-2 shift is l occurring about 2800 rpms but better than the 2500-2600 rpms I was getting before. Also, the kickdown from 3 to 2 lags and takes about 2-3 seconds to downshift. The 2 to 1 downshift is non existent. I check linkage and throttle lever is all the way back against the stop at WOT. Trans shifts tight with no slippage. Bands adjusted per kit specs. What's next, governor weights? line pressure check? New Trans??
Did you take the governor apart? Did you check the governor seal rings? some governors have a screen to catch debris. Even a low performance governor should shift higher. Unless the throttle pressure linkage isn't correct. I'm asuming you checked the throttle pressure valve and cam along with the shift valves for freedom of movement when you installed the TF 2 kit?
