Converter lock switch up

It had to be simple to install, and most importantly it had to work without any interface from the driver. The solution was a timing based module system that activates the converter only after the transmission has shifted into 4thgear. The basic operation is quite simple. When the transmission has shifted into 4th gear, the pressure in the valve body closes a pressure switch that then creates a ground input. This completed circuit activates a 10 second delay timer that when finished, connects the ground signal to the torque converter lock up solenoid, thus locking the converter clutch in.

This connection stays active as long as the transmission is in 4th gear and the circuit is completed. This pulls the converter out of lock up to allow the car to easily accelerate back up to speed before the lock up re-engages. The entire lock up system can be installed by anyone with minimal mechanical skills. The internal components are all accessed by removal of the transmission pan and filter only.

There are no special tools or procedures required. We include every component needed to connect the system and get it working properly.

This ensures that regardless of if you have a newly re-built unit, or a unit that has been in service for years, you will be confident that the parts are correct for proper operation.

This feature is often controlled by the vehicle's computer when certain conditions are met, however this can be bypassed, and a toggle switch can be used to control torque converter lockup anytime the driver wishes.

Drive the vehicle onto car ramps, put it in park, and set the emergency brake. Put on safety glasses and place a large drain pan under the transmission pan. Loosen the transmission pan bolts four or five turns each, and gently pry down on the edge of the transmission pan, being careful to prevent any bending or warping.

Allow as much fluid as possible to drain from the broken seal between the transmission and transmission pan. Place one hand firmly on the transmission pan and hold it to the transmission case. Remove the transmission pan bolts by hand and slowly lower the pan down into the large drain pan.

Remove the filter by pulling down on it. The TCC solenoid is connected to the valve body of the transmission. Disconnect the negative and positive terminals of the battery. Locate a body ground under the vehicle and attach one end of the gauge wire to the body ground.

Run the ground wire through the transmission wiring grommet, and attach it to the negative side of the TCC solenoid. Decide where the toggle switch will be located within the vehicle, and install it.
