Wrangler Manual

Can I simply replace the manual transmission on MY 2004 Jeep Wrangler Rubicon with a transmission rate of 2005?
I bought the 2004 Wrangler Rubicon on a whim (an error on this page has saved me $ 1,000!) I began to research and I realized that the Jeep transfer changed in 2005 from a 5-speed with a 6-speed. In my 5-speed, first Gear is too weak to one-way street, lead So I start from 2, which is too high, and I burnt my clutch. I want it with a manual transmission 2005, a lower speed first, but has also replaced the second lowest, give me a better "on top of the street" 1 Course, and I still have 5-speed efficient. My basic question is: is a given that the engine is the same 4.0L I-6 bolt transmission of messages directly on the engine, or are it is incompatible? (I think I have enough information, but I will provide more if necessary)
Yes, you can transfer but a transfer Swap is never easy operation. But since you have already saved $ 10,000, you can afford to distinguish from a professional who is to optimize the transmission Your needs.
