Been thinking about it for awhile. Ive tried the solenoid, sensor and shift kit.
The shift kit did get rid of the shuttle shift, now it shifts into 3 gear very early. Hardly uses 2 gear unless your really getting into the throttle then it shifts great. Which leads me to believe that the "weird shifting" is due to throttle position which the shift master alters. Anyone else??

 

i know the dtt shift enhanser can raise shift points dont know bout the ts one.if you used the transgo there is a spring that you can install that lengthens out the shifts
