Holy crap this is a sticky? LOL.
Well I have another truck because my dad cut down a tree on the other one, the 94.

I now have a 1996 Chevy S10 with a blown 2.2 my dad bought to replace the one he crushed.

I still want to do a diesel, and do a waste vegetable oil conversion.

I've found a Perkins T4.236 at my dads work, but it was ran out of oil (still runs but has top end noise) and my dad also knows for an Isuzu diesel that runs, although we don't know any details on it.

I've also found a Mazda built Perkins from a Mazda B2200/Ford Ranger. Guy wants $850 for it and it comes with tranny, 226K. I don't feel that it is worth it and its in Manitoba, and I'm in Alberta..

One problem is, I have to have an automatic.

I have a 4.3 V6 4L60E, I've found a manual shift kit that does not require a computer however it comes with a vaccuum module to controll the line pressure and as far as I know, this won't work on a diesel....
I would like to be able to use the trans I got.
