76cj5 with a NP435?

How much more trouble to put a NP435 in an intermediate than a T18? I Have the T150 now.

Having trouble finding the T18 without spending more $$$, but is it a wash when making the NP435 fit?

Ive searched some but was hoping for a link/reference or just an answer.

Thanks guys, youve always been a big help!

 

off the top of my head, adapters make a 435 too long for a CJ5. I put in a 79 T18a, which is the shortest truck 4 speed combo you'll find, and my rear driveshaft at rest is 16-1/8"

 

The adapter(s) will be expensive so add that in to the cost of the tranny. IIRC there is a short shaft kit now for the 435 so length is not as much of an issue.

 

hmmmm. so the 435 i've been running in mine for 3 years doesn't work?

i used the novak kit. the kit includes a new mainshaft, which is shorter than the 435's original. the kit also includes the adapter to mate to the dana 20.

i'm not positive, but i believe that a dodge version, with 6.68:1 first ratio is out there, and has a pattern that matches the dana300. edit: to clarify, this would work well with a 318 motor. not sure if using the dodge version would work for the 258/304 etc.

 

good info here....

Pm sent Steve!

 

Got one in my '72 CJ6. Love the transmission, its a huge impovement over the T150. I used the Novak kit with no install problems that I didn't create myself. I went with the NP435 because it had a lower 2nd gear which I figured would be what I was starting off in most of the time. I'm extremely happy with the way it drives.....

But...

It hangs down a lot. With a CJ5 it might not be as much of a problem, but if I had to do it over again, I would go with a T-18 just because it tucks up between the frame rails much better than an NP435. With a CJ6 2.5" lift and 33" tires, it hits everything on the trail. I have actually seen rocks sneaking in from the side of the trail so that they can get hit by my NP435.

 

Sorry to bring up an old thread but does anyone have any pics of how low the 435 hangs??

 

This in a 1974 with a custom tranny mount, but you get the idea.....

 

Work in progress.

 

Here is the info off Novak's site I keep handy.
SM465+adaptor for Dana 20. Length = 13" Ist = 6.55, 2nd =3.58
SM420+adaptor fo Dana 20, Length = 15.2" Ist=7.0, 2nd=3.6
NP435+adaptor for Dana 20, Length= 14.2" Ist+6.68, 2nd=3.34
T18+adaptor for Dana 20, Length=12.9" Ist=6.23, 2nd=3.09
