Need Help with My $400 94 Truck

So I bought my 94 C1500 Ext Cab 2WD (auto) for $400, when I bought it I knew it had Trans issues, 3rd(D) slips like it isn't even there. I have no Idea of OD it there or not, never got the truck going fast enough. On the way home the Engine started to sound like an air compressor, sounded like it was coming from cyl 1. A compress test put cyl 1 @ 90 psi, with the rest I tested at 120psi, Changed the Plugs because they had some kind of Build up on 3 of them. I am in the pulling the motor, since I am sure it is a bottom end issue.

I am pretty sure the trans is a 4l60, since the linkage looks all mechanical, and their looks to be a single plug with two wires near the tail shaft. I was wonder if I can get a 4x4 trans to bolt up, or if not what vehicles to pull from the junk yard.

I have also considered a Manual trans swap if I can find the parts at a good price.

I am still on the fence if I want to rebuild the motor or swap in a different one. If I could find one locally I would swap in a 4.8L.

I have never rebuilt a Small block chevy before, I am more familiar with Wankel rotary engines.

alot of work turning a 4wd tranny into a 2wd
you can use the 4l60 from a astro or fullsize van
but double check what years will work,I believe there is a early 90's and late 90's 4l60
Is it the same trans on the 4.3?
the tq converter is slightly different and will stall a couple 100 rpms higher with a v8 but it will hardly be noticeable
