How does it work?

When do you engaged it?

How does does it improve 0-60 times by 3-5 sec ?

thanks for the help guys.

 

You jumper the torque converter clutch relay and run the control to a toggle switch in the cab so that instead of the tranny control module telling the TCC to lock in, you're telling it when. The TCC in a torque converter works like a clutch on a manual transmission by locking the coupling up giving it a 1:1 power transfer. It's just that with a TCC the TCM does all the controlling of the clutch instead of your left foot.

You can lock it in at any speed. So if you're starting from a stop and hit the switch at 15 mph it locks the TCC. This eliminates a lot of the slip from the converter. Eliminating that slippage is what will increase your 0-60 times. The downside is that you have to make sure that you disengage it every time you stop or it'll kill the motor or break some parts and it creates a lot of heat inside the trans.

 

so if i engage the auto lock at 15mph will stay in first or will i shift gears while i incress speed?

So im geussing this is alot harder on a stock tranny and torque converter?

 

It still shifts the same.

It's a little harder on the stock stuff. If I were you I would just spend the money to upgrade your trans. A better TC will do wonders for you.
