NEED A “LOCK-UP” CONVERTER ?
The greatest source of heat in an automatic transmission is the torque converter. This is because there is a constant source of friction within a torque converter and as we all know, friction creates Heat!.
Even the most efficient low stall torque converter will never stop slipping, so you will always have that source of heat generation in a non-locking converter.
When you add stall speed to a torque converter you are raising the RPM that the converter must attain before it transmits full engine power back to the transmission. While this is great for performance, it creates an even greater heat & transmission efficiency problem.
To make matters worse, in an overdrive transmission, even with steep gears, the engine rpm’s at cruise may be substantially less than the stall speed of the converter, which is a recipe for disaster! By applying a Torque Converter Clutch you eliminate this slippage and heat source, allowing you to have the benefits of a performance oriented stall speed, plus economy, efficiency and finally “lower” operating temperatures.
DO I NEED A COMPUTER OR SPECIAL WIRING IN MY NON-COMPUTERIZED CAR?
NO, with either of our 700R4 and 2004R performance transmissions, only need voltage to control the torque converter (lock-up) clutch solenoid, all the shifts are performed hydraulically. We wire our transmissions up internally so all you need to do is attach a 12 volt source to the supplied pigtail wiring harness and the transmission will do the rest.
