Tranny swap advice?

The problem is that my 5 speed is grinding in 2nd gear and its just a matter of time before it goes. Here's a few options I've been toying with:
1. Swap a ford t-18 in its place and buy the adapter to match the np231

2. Get a 350 chevy with matching 4 speed and transfer case - don't have but can get it.

3. I've got a running 304, t-150, dana 20 - put it in

Another determining factor is that I've got several things that my current setup needs: exhaust, new carb, rear main seal, power steering pump - why put the money in it now, only to take it out later.

I would like to do this as cheaply as possible yet reliable as well. Also the side of the front differential doesn't matter.

Re: Tranny swap advice?

What do you want to do with it?

For the cheapest swap, I'd run with the 304/T-18/D20 if you're gonna crawl or the T-150 if you're mainly on the road.

Re: Tranny swap advice?

I'm wanting it for a daily driver/occasional off-roading. I don't need to go really low - there's not too many rocks here in Iowa.

Is the T150/D20 setup fairly reliable?

Re: Tranny swap advice?

Yes, it's a strong setup, it just has a 3:1 first so people usually swap it out and not in. They were put behind some larger motors, so it'll handle the 304 easily. The T-150 was stock behind the 304 anyway.

Re: Tranny swap advice?

Check my BA-10 to AX-15 post. You can keep your x-case and your driveshafts (even your clutch) this way.... Best you can do (except NV4500 or something) for a daily drive as you keep the 5th gear....

Re: Tranny swap advice?

I'm actually leaning towards putting in the 304/T150/D20. Does anybody make engine mounts for a 304 in a YJ?

As far as the Ax15, I think I would have to change the input shaft on the NP231. Its got a different spline count.

I will go with the 304/T18/D20 combo even if you dont need the granny low 1st. You will get a stronger tranny that can be used on the street like the T150. With this combo you shouldnt have to worry about broken parts.

Re: Tranny swap advice?

HE asked about doing it as cheaply as possible, and he already has the T-150, so that's why I recommended it. The T-18 would be nice, but they CAn run into some $$$.

Re: Tranny swap advice?

I would prefer the T18, but I know the T150 works. I've got some time before my setup gives out, so I could always keep a lookout for the T18.
As far as the clutch goes, would I have to swap all the CJ parts to the YJ?
