Trans Stuff
It all comes down to money, and function! I've spent thousands on cars and trucks, that weren't broken..... The "Fun Factor"!!! If you have the money to spend on "Fun", then get the best bang for your buck. If you want "The Best"....... you gotta pay! I'm throwin' down 400+ Hp, and well over 800 lbft Tq. I can roast my 37" BFG KM2's all day long, and leave a lot of sports cars in a fog of black goodness! That said, is that how I use it all the time...... well, only when it's necessary. The truck if fun to drive, but it is my daily driver and tow vehicle. It was built with a purpose in mind. ABSOLUTE reliability and strength. It is always making MAX power, and I tow a 13,000lb Toybox in OVERDRIVE! I'm "That Guy" pulling big grades at 60-70 mph. Long story short..... you would have a hard time finding someone that broke a John Wood Custom Transmission. However, you gotta take it to him, if you want it done right. He builds the transmissions according to your equipment, driving habits, and intended use. You gotta be honest with yourself on the "Driving Habits".
But, it doesn't seem like you're looking for a complete trans. That said, give John a call! (jwtt.com) He knows ALL of the manufacturer's equipment. He's pretty cool at advising you on equipment changes, with what you have to spend, and where to put it.
Good Luck
