onestophop wroteIt's time to rebuild my TF727 and I'm looking for the best way to build it. The CJ7 has a 360 howell efi, TF727, D300 & 37MTR's. I DD it once a week and trail ride it about eight times a year. What torque convertor should I be looking for? I want it to shift smooth. I drove one with some type of shift kit and it shifted hard.
Hey, I'm a newbie here but I'll add my two cents since I have a Jeep and chose my torque converter based on my intended use. Depends what you want to use the CJ for really. Offroad is about putting your torque to the wheels, you want the largest diameter, lowest stall speed. In a street application, you want a high stall, small diameter torque converter for the high rpm launches. Obviously, there is an in between ground based on how you intend to use it before you commit.
The shift kit is a block off plate that modifies the function of the hydraulic valve body in application of the shift points. I don't really understand how the various ones work exactly, but thats what they do. The stock soft shifts wears the frictions and bands prematurely. The auto tranny is designed so you don't feel it (hardly) shift in stock form. The shift kit gives your tranny longer life.
I have a T400 behind a 401 and I have the shift kit. I like it for offroad. I also have the Marv Ripes heavy duty planetary with 3:1 first gear. I have the 13" (IICR the largest on that fits) torque converter. Hopefully this helps a little.
