1988 v 30350 4x4 manual

[Louie krieger]

I have a 1988 v 30 4x4 350 efi dually with a standard transmission sm465, what kind of automatic would work its a dump truck with plow. And with out the transmission being synchronized its to hard to plow with and now transmission is blown. Front drive shaft is on passenger side it has 4:56 gears dually it has a np 205 or 203 ( its the cast iron heavy one) can some help. I am about to retire and want to fix before that happens .

You should have a 32 spline np205. A th400 would have been the automatic transmission offered in that truck, you will need the correct trans to tcase adapter to bolt it to your tcase. The real trick is getting a transmission with the correct length tailshaft as they are not all the same.
