Transmission Tune Only for EFI Live Spade LWN (2018)

This TCM tuning works with ECM tuning to provide smooth shifting and superior drivability. It features a torque converter lockup strategy to put power to the ground, better acceleration, quicker shifts, and prevents short shifting in performance use. It improves clutch holding capacity with increased line pressure. This is an important upgrade for trucks with ECM tuning, larger tires, bigger turbos, or built transmissions. It electronically controls line pressure and shift timing to give firmer shifts and ensure the transmission has enough hydraulic pressure to hold clutches tight with increased torque.
