first gen trans swap?

[ramboy1990]

this is just an idea but i was thinking
about swaping the np435 thats in my 90 1/2ton
for a nv4500 from a 94+ 5.2
anyone done this?
im just wondering if the nv4500 would mate right up
cus if it wont i wont bother

I have been told that the old 727 will bolt up to my 96 360 you just have to find the computer for the engine that was out of a manual trans

I have not tried this but have been told this a few times

WTF does that have to do with him swapping an over drive manual 5 speed in his truck?

[mopar]

with the right bell housing it will bolt up

i have got a 2000 trans bolted to 2 92 engine just have to find the right bell

[redjosh]

baja it has to do with that wierd sh&t fits that you may not know will

so its worth looking in too and shut up cause you gave 0 info that helped you post [censored]

wait a sec one question the 5speed 2nd gen
5.2s 5.9s
are they nv 3500 or nv4500ld?

because its those trucks that gave me the idea
and im thinking that a 94+5.9 would be the same bolt pattern as my 1990 5.9

[ramboy1990]

red josh ur 96 is it a 5.9

the 5.2's had teh 3500 and the 5.9's had the 4500.

[redjosh]

yes my 96 is a 5.9 but only for another month then i will have my 440 i will try and bolt the 727 to 5.9 just to see if what i have been told is rite or not

Yes, you really should post some tech you post whoring b*tch!



In terms of purely "unbolt this one and bolt that one back in its place," the answer is no.

An NV4500 is a few inches longer in case length than an NP435. I don't know about bellhousing depth, but I can't believe a NV4500 bell is appreciably shallower than one for a NP435.

Beyond that, I believe the output shafts are different. I may be wrong. I think the NV4500 has a 1-1/2", 29 spline output shaft whereas the NP435 will have either a 28 split output or a 32 spline out. Perhaps somebody more experienced in vintage Mopar "stuff" can correct me or add to what I've typed. So, without some fashion of a conversion tailhousing AND a transmission output shaft to t-case input shaft conversion "spud", it's not going to be a bolt-in swap. I would have to think some crossmember modifications would be required, as well, and probably driveshaft modifications two.
