GM Transmission Tuning with the TCI EZ-TCU and New Fast-Gate Shifter

The world is filled with tuning solutions for engines, but what about transmissions?  Late model transmissions have become as advanced as EFI systems with their own dedicated ECUs. Based on FAST’s EZ EFI ECU,  TCI’s EZ-TCU lets you take control of your late model GM transmission.  It allows you to take advantage of shift points, firmness, and shift speed. Want to increase the line pressure?  Simply wire the ground switch to a toggle and have a firmer shifting transmission with the flick of a switch.  Additionally, data logging and self diagnostics allow users to fully monitor the transmission. It is easy to use and comes pre-programmed.

• Easy to wire
• Designed for all skill levels
• Data logging and self diagnostics
• Adjust shift points, firmness, and shift speed.

TCI is displaying their new Fast-Gate shifter that is universal in design, allowing it to be used in virtually any 3- or 4-speed application, either street or race. It also includes a injection molded cover, cable and all required hardware for a simple installation, so there is no need to be extra accessory pieces. Additionally the reverse lockout mechanism eliminates the chance of transmission damage from accidentally shifting into reverse.
