Help

I recently bought a 1978 cj7 with 3 speed t150 it has the 304 but second gear won't hold unless you physically hold it in. I would like to get first gear down a little lower but can you guys give me some suggestions like what a t18 swap entails.

T18 swap entails a shorter bell housing, and a shorter ouput shaft on the T18. I found a bell on fleabay for~ $100 and a shaft at Novaks I believe. You will also need a tranny to Xfer case adapter. The driveline will have to be adjusted for length as well.

Or you could rebuild the tranny you have now.

A t18 swap and a Teralow will be the same

Money by the time your are done. Driveshafts have to be changed with the t18 so that adds $400-500 right there
