Thanks for the reply about tranny's. I called AA for prices on adapters. The adapter to the transfer case is $546.80 if you get a 700R out of a 4x4 truck, and $580.55 if it's out of a 4x2 truck. To mount it behind the 258, it requires an adapter priced at $360 plus the flex plate. Then you need a tranny. Just wanted to let you know. It seems a little expensive, but I want to find out the total cost of swapping in a T-5. My Jeep is a daily driver, and there are no rocks to crawl over down here in Florida. I'm still curious about the gear ratios of the front and rear ends. One guy, a used parts finder, who I spoke with said the T-5 wouldn't work with the stock gears because it would just bogg down when I put it in 5th gear. Before I decide what to do, I want to know what all my options are. Do you have any other suggestions on how to get an overdrive tranny into my rig?
