looikng for transmission advice

[big.d]

ok,i bought this truck used 2001 f250 psd.4x4 4 door,it looks to have a reman ford trans in it, the truck has 145,00 on it the guy i bought it from said he replaced the torque converter less than 5000 ago with a stock one,my question is, it doesnt lock up very well under w.o.t. with the juice cranked up,what would be the way to go to help it perform better towing and just playin,without buying a new one?

You could upgrade the Tq to our 6.0 Tq converter and do a DYI VB kit for firmer shifts or get a BTS VB.

You most likely are not going to feel a real solid lock-up on a PWM controlled TC lock-up. It is ment to be smooth. You would have to make internal changes to make it more firm or on/off. Install a Trans Go tugger kit is a good idea to help performance. If you can't install one yourself, then buy one already installed.

Going the Tugger route, do the pump mods. While the pump is out change out the PWM valve with the E4OD lock up valve. The converter will be happy.
