We have the 1979 CJ5 and have found a T-176 & Dana 300 a guy wants to sell for 600. Would like some advice on that combination verses the T-18 possibility. And need to know if the bell-housings we have will work for the T-176? The bell-housing we have is the stock one for CJ5.
The other question then would be do you the the T176 is the best way to go. I am thinking that it is for one thing I was told that the T18 doesn't bolt up to our transfer-case you need an adapter that cost $500. I think that the T176 will be closer to a bolt in.
We are planning on mostly highway driving and some trips to Moab but nothing sirius
I chose to go with a T-176/d300 combo in my CJ5.
I went this way over the T18 because for around the same money as adapting a T18 I could get the LowMax 4:1 kit.
So I can have a "real" 4 speed and the same low gear as a T18, and a broader selection of low gears to chose from, with out the big jump from 1st.
I'm waiting on my new 258 from the machinist to so I can install though.
I Liked the gear spread on my old AX15 and the T176 is close to that minus the 5th gear.
I got my T176 in the back of my CJ when I bought it. I bought a D300/SR4/ and skid plate later. I sold the SR4 for what I bought the D300/SR4 combo for. so even money.
T176 is longer than the T150 so it is a shorter distance to the rear axle, and a longer distance to the front. you need to shorten (possible Double cardin) the rear, and get a longer one for the front.
the length issue is also why we CJ5 owners are pretty much stuck with the 4spd. unless you stretch the wheel base, or stay on the road.
