Hello all!

I hope someone can guide me in right direction. I have a 98 wrangler with a 4.0 and a "new" 3 speed auto that the previous owner had put in. My question is what/or is there an overdrive transmission that can be used to get better mileage? I don't want go through the hassle of changing to a manual tranny as this is my daily driver.

Any help or input would be greatly appreciated.

I really don't know. It's an auto 3 speed, should be the original kind of tranny. The previous owner said he put in a new not a rebuilt transmission which was probably an off the shelf rebuilt exchange.

Bottom line, Jeeps do not get good mileage.

I am thinking about getting a set of 31x10.5r15 cooper discoverer ht's on what I think are called "GAMBLER" wheels.

Anyone have any thoughts on this?

I know light truck tires went through the roof since the last time I had purchased any!

The larger tires will probably help slightly on gaining highway mileage but around town you will be using more gas to turn them and get them moving so it is kind of a wash unless all you do is long highway trips.
