How do you change the transmission fluid on a 1998 jeep wrangler with a manual transmission?
IN YOUR QUESTION you asked how much it would cost to change to an auto matic transmission. That cost would depend on where you take it. An auto matic transmission fo rit would be around 1,005 dollars on the site that i found plus shipping http://market.autopartsfair.com/jeep-transmissions/find_product.html?make=jeep&model=wrangler_4wd&year=1998 . but you will still need to get a shifter and several different things in order for it to work. I would have to say at the least it may cost 2,000.Good Luck.
