I see you are from Minnesota. Most likely wasn't your yard. It came from NY.
Search the new york company's website for an Allison trans for an 02. Maybe you can find a listing with pics of the truck
I am upstate as well, and could use some spare parts :hug:Idk why my stuff says I'm from Minnesota but I'm from upstate NY. Will get this figured out.
An engine sitting that long may not have any oil coating the cylinders or rings thus causing low compression. May need to change the oil, then prime the oil pump and spin it over a bunch. Maybe just squirt a little oil into the glow plug holes and test again. Also, what rpm was it turning over at?
You get what you pay for. And calling Tom a Dick because You Certanly DID ask for help was a dick move. Just sayin. Hope it all works out for you and next time you dont go easter bunny hunting. I get low mile dmax engines for 2500 round here.
