Torque converter


Feb 7, 2004
Hi, can someone explain to me in terms as though speaking to a five year old,
the difference between a lock up converter and a non-lockup ? My car is used
for cruising only had it to the track one time, do I want a L/U or non L/U and
why ? thanks
If your car is a "cruiser" or daily driver you want a Lock up converter.

What that is; is internal to the torque converter there is a clutch system, that has extra fluid applied (at the appropriate time), and it engages the clutch, which like any clutch will lock the engine to the tranny (no slippage, or very little).
Great for fuel mileage. Helps tranny run cooler also.
