What is the difference between a torque converter, shift-kit, and J-Mod? Do they all work together? I need some clarity! Thanks guys.

A torque converter is inside the transmission. This allows you to stall your car to launch it in a drag race. Stock torque converters are usually in the 1800 rpm range, maybe a little more. By changing the torque converter to say 2500, you can stall the car at a higher RPM. The Jmod is a shift kit for the ford tranny. One of the best things you can do for the auto ford slush-box. Yes, all the components work together. The stall (torque) converter, helps by revving higher on launch, the jmod or shift kit shifts the tranny faster and smoother(sometimes harder depending on setting) for precision shifts.

The J-Mob is actually one of the best things that you can do for your transmission as it increases flow and helps to keep the tranny cooler and increases its life not to mention performance.

A highly recommended group of mods for V6 autos are as follows.

1.) J-Mod
2.) External Trans cooler
3.) Tuner

+1 on the tranny cooler

Ok...I'm going to get a JMod next! That should give me the shifts I'm looking for.

You don't really "get" a j-mod. It's what the name implies... a modification. It was created by some dude named Jerry who happened to be the engineer of the 4R70W. It involves drilling to make a some of the holes bigger in the separator plate. This helps the fluid flow better resulting in a quicker, firmer shift. A shift kit adds different actuator springs, valves, etc... all of which is not needed and can actually be bad for the transmission.

Another option is to send in valve body to Steven at VAPauto and he'll clean it up, perform the mod, and send it back to you for $59. Best bet would be to find a used valve body (ebay, forum, junkyard). From what I here on 3.8mustang and v6power, he is great to do business with...

technically the torque converter is between the trans and engine and takes the place of a clutch allowing the car to some to a complete stop without stopping the engine. a "stalled" converter is just a torque converter that doesn't hit the level where the prime mover can make the turbine move till higher RPM that a stock unit and it primarily used in drag racing when installed in a car, but they are also used in work trucks that pull heavy loads like stumps or stuff to get more torque to the ground without locking the torque converter and spinning the tires. They are even used in water crafts.

Yes it is neo, don't forget the flexplate.

unless you forget to put it in and can't figure out why the car isn't moving... like my friend did, lol, but yeah I never mentioned what pieces the torque converter connected to on either side cause i figured people would know that much... guess i give people to much credit huh

Ahahahaha, nice story, TOO FUNNY!!
