Will a IH T19 work in my cj5
I have a T150 that's jumping out of gear and was thinking about doing a 4 speed conversion instead of rebuilding. I would like having the granny gear with my 3:54 axel ratio. I was thinking about the ford T18 but today a friend offered me a IH T19. He thought I would need to get the input shaft machined shorter, other wise thought it would be the same as the T18. wondering if anyone on JF could shed some light on this for me. I have searched for a while but only found info on the ford T19. I also have a 304/D20. Thanks in advance!

Impractical is the word. The IH transmissions thread into the bellhousing from inside the bell. I'm not sure what bellhousing you would use.

The Ford T-19 makes a great CJ tranny. It's as bullet-proof as a T-18 with the additional benefit of synchronized gears.

The IH T-19 sounds like an odd-ball that wouldn't be worth the effort to stick in a CJ.

Found a ford T18! I'm going to start the swap when the weather warms up a little. If I'm set up for the T18 and later find a T19, would it be an easy swap? Also I read that I either need to do a 1'' body lift or lower the trans crossmember to make it fit, I'm thinking body lift as to not loose ground clearance. Any suggestions guys?

T18 is a great trans. Has a great 1st (granny gear) which you pretty much just use offroad. Good for super slow. It's basically a 3 speed with a crawler gear.

Most T19's don't have the awesome 1st (granny gear). Most are like 4.02:1 or something like that. 1st gear is synchronized. Because of 2nd gear being 2.41:1, it is truly a 4 speed and you will always be using 1st gear for normal driving. Try to start out in second and it will do it, but it will be a dog.

For clearance just trim the floor. I can't imagine it needing that much trimming to fit. If you drop the cross member rear drive line angle improves, but at the expense of front driveline angle (worsens). 1" body lift can be helpful in resolving a multitude of clearance issues, but opens up other issues, like will your steering stretch far enough, will your clutch continue to work, now there's a space between bumpers and body. Those are just a few off top of my head, I'm sure there's more.

Thanks for the info on the 1st gear, didn't know that about the T19. I thought I herd something about using some scout 4 speed parts to make it work, I think it was the main shaft. I do have access to them if needed. Any idea?

CSP 01-25-2014 02:25 PM

Not sure what you're referring to with using Scout parts. To make what work?

To fit the ford T18 in place of my T150. I've read lots of swap info, probably got mixed up in my head. Pretty common problem...
