TCI AUTO-X GM LS 4L60E Transmission Package provides engine braking for all GM LS and 1998-2002 F-Body applications.  Purchase thru Marken Performance includes a TCI EZ-TCU, as well as a paddle shifter.  In autocross, road racing or off-road competitions, engine braking is a necessity when slowing down to enter turns.  This new transmission package from TCI® provides it for GM 4L60E applications and includes a TCI® EZ-TCU™ along with a paddle shifter.  The package offers crucial engine-braking capability in first, second and third gear when the shifter is placed in the drive or third-gear position. Upshifting and downshifting can be controlled with the paddle shifter while the EZ-TCU™ is set in manual mode.  However, when the shifter is placed in the overdrive position the transmission will operate without engine braking enabled. No stock transmission offers this kind of control. Users can employ a TCI converter featuring any stall or simply keep using their stock converter.  The package is not compatible with ’97 and up Corvettes.
