Information CJ5 with 2.73 gears
 

82 CJ5 258 with T176 four speed, 2.73 gears, 31" tires.

I realized this afternoon that at 55 MPH in third gear I'm only turning 2800
RPM.
I was pulling my boat up a long hill which I normally take in forth. Just
thought I would try third.

With these 2.73 gears it's almost like I've got a three speed with an
overdrive.
I rebuilt the T176 transmission myself last year an it's working great, but
I don't think it was designed to be run in third all that much.

I know, I need to regear. But I doubt I will.We just use it on weekends to
hunt and fish. Trips are normally less than 20 miles.

It's pulls the boat pretty good. It's a commercial duty 15' johnboat with a
25 Mercury on a heavy duty trailer.
You just don't take your eyes off the road much. One day while pulling the
boat I met a big truck in a curve and for a few seconds it was like on
Apollo 13 when they where manually firing the rockets on the lunar module to
get back on track to earth.

The first time I pulled the boat I thought my power brakes had gone out. It
was just the weight of the boat.

Seriously though, I'm extremely careful while towing. And 99% of the time
it's enjoyable. I don't tow on the interstate highway.
About 60 mph is as fast as I ever go.

Hi Mark,
31" tires and 2.73 will definitely make your 4th gear an overdrive. I don't
think the transmission cares what gear you run in as long as it's not at
extreme RPM (and what that value is... I don't know). (let's see... what
was your question again?)
