nothing to do on a t-shift unless u want to make it a true twin stick(front and rear operation) u will have to remove the pills. the shafts are linked by a removable plate held in with pins, no cutting required like the j shift does. if u leave it alone u will have 2h, 2low, 4 h and 4low. if u remove the pills u can have front high, front low, rear low, rear high, and if u want to blow something up u can do a combination rear high, front low- but I dont recomend it. the only advantage to removing the pill is that u get independent opperation of the front axle, nice for tight turns but other than that its no big deal for the work involved.
