Allison 1000 trans-shift kit install


Active Member
Would like to install a shift kit in my 2002 Allison 1000 trans. Anybody actually done it in their garage? What brand kit is best.
go to ats diesel .com .we have used several with good luck.the problem is you need to install the copilot upgrade if you plan on raising power output because a millisecond of clutch slippage due to increased engine torque will put the trans in failsafe.
