Re: Opinions about auto. trans.
Building a TF904 is like building a rocket powered Volkswagen Bug. It can be done, but why? By the time you've invested the time, money, and parts into the build... you could easily buy and install a TF727.... or if you want to spend a little more money adapt a TH400 on to the engine.
There is little difference beween the 904 and the 999, they share the same parts. The 999 has one more clutch disk... that's about it.
As for a converter, use the one that comes with the transmission you buy. Or buy a new one. Here you can also go a little crazy with lowering stall speeds, etc., so do you homework 'cuz there's lots of people out there who'd love to take you money and give you little value for it.
There are other transmission choices, but they will cost a little more. IMHO, if you're going to play in the mud with your larger tires, the TF904 will work, but only for a while, and then you'll be walking out to get parts and start all over again on a reubild.
Happy Holidays and Safe Jeepin'
