Transmission change?

What's involved in a transmission change? No, not a fluid change. An actual CHANGE - from auto to manual? How much money/time? Thanks! -Ashley

Re: Transmission change?

Well that change out is usually done in the reverse. But It can be done. The hardest part will be to get the swing arm assy. and either hydr. or mech. master or linkage which ever you use in place. The easiest would be to get a donor vehicle of the same year and make and transfer the parts over. Keep in mind that the computer in the newer units will need to be addressed. You may have to change out and eliminate some pick-ups. The drivelines will need to be changed due to length. Flex plate will need to be changed to a fly wheel and the appropriate pick up needed there. I may have missed a lot of things. I just did this in reverse last year pulling the standard and installing an auto. Much better to rock crawl with, IMHO!!!

Re: Transmission change?

IMHO - given that your Jeep is essentially "new" will spend less money and find less trouble to sell your current automatic transmission TJ and buy a different TJ with manual transmission.

If you are set on swapping, points to ponder:

Will need manual specific parts like: clutch, flywheel, clutch master and slave cylinders, clutch/brake pedals, etc.
Current electronics will need to be tapped into for the Jeep to know about the auto to manual swap
Will need to put that annoying little "shift light" bulb in the dash panel [img]images/icons/crazy.gif[/img]
Given your TJ is 4cyl, you will also need to get the transfer case from the donor. Else swap t/c input shaft too as the input spline count is different from auto to manual on 4cyl TJ.
Transmission length is different too, so drive shafts will likely need to be swapped as well. (or modified)
is the shifter console different for TJ?
Sorry, I don't know accurate cost... but estimate about $1k if you do the work yourself.

Above are only some of the details that will need to be addressed before making the swap you mention... if you really want to do it, this is a great place to find information and help and knowledge and opinions and most anything else. Even if you don't do the swap... still lots good here to find out. If it is performance or better hwy manners you want to change, ask that too...

Welcome to the BBS, Ashley. Enjoy your stay and your Jeep.

last but not least... it is a Jeep, not a car - hence the name

Re: Transmission change?

Just curious as to why you would want to change out your auto. Mine is an auto and it is great for trail riding and rock crawling. The last issue of JP Magazine had an article on the pros and cons of both. Just don't let your auto get under enough water that it fills with water and mud - expensive. I avoid deep water.
