The tow master would be fully rebuilding it with his converter, his clutches, his valve bodies ect...
We have recently begun stocking his stuff. We have installed a few tow masters already in the short few months of being a dealer, extremely high quality is all I can say.
There have been zero tuning adjustments needed thus far when running his stuff. They shift perfect, on time, every time. The shift is very very crisp without anything banging or slushyness.
That tow master has been dyno tested in Jacob Whites single cab at 900+ hp. I am not saying that is practical, but goes to show what the transmission is really made of.
$5700 out the door includes labor, full rebuild, the transmission, the synthetic fluid, a fluid flush, and him re tuning it after if need be. He writes his own transmission files to go along with his transmission which really brings the whole package together!
