Summit Racing™ torque converter lockup kits are a simple way to control converter clutch lockup in 4th gear when swapping a GM 700R4 or 200-4R transmission in an early non-computer controlled vehicle. The adjustable vacuum switch will hold the clutch on during steady state cruising and disengage when accelerating or downshifting. Summit Racing™ torque converter lockup kits are available in automatic (+12V applied via vacuum switch) and manual (+12V applied via toggle switch) versions. Choose the one preferred for your application.
