Re: NV4500 swap installed and rollin!

Quote:
The sm465 got a different bellhousing(passenger side external slave) and an aluminum shift cover with a more rearward shift position, when it was installed in the gmt400 trucks. The rest of the transmission remained exactly the same as the one used in the 87-91 R/V trucks. When the sm465 was swapped out in the middle of the model run for the nv3500/nv4500, those two transmissions were sized to fit exactly in the vacated space.
So ... does that mean an SM465 would just drop into a 1989 GMT400 with the NV3500 ?

(I know you're asking "Why?" but I use it more off-road than on the highway so the granny gear would be more useful than the overdrive)
