Why would you want a non lockup torque converter?
When a torque converter clutch is engaged, it creates a near direct-drive effect and slippage becomes virtually non-existent, regardless of rated stall speed. A non-lockup converter can build excessive heat during normal cruising, especially in overdrive when engine rpm drops below converter stall speed.
Do all torque converters lock up?
1. Engine temperature too cold – most converters will not lockup until the coolant reaches about 120°F. 2. Overdrive unit locked out – when an automatic overdrive is “locked-out” the torque converter lockup feature will also be locked out.
Do I need a lock up converter?
The Bottom Line. A lockup torque converter is important in automatic transmissions to reduce slippage. And once slippage is curbed, heat generation is minimal while fuel economy is improved. This and many more have been outlined above to give you an insight into this component and why you may need one.
What’s the difference between a lock up and non lock up torque converter?
Towing will add heat to the transmission. A non-lock-up torque converter will add more heat. With a lock-up when you get to speed, the torque converter will lock-up, which creates a direct drive from engine to transmission.
