It's not a truck Lee, but.......
Picked up a 2000 Blazer 4x4 auto.

Runs great

, but barely moves

. Basically, it moves in 1 and R, but as soon as there's any heat in the trans, it completely dies. Luckily, it worked lone enough to get it on the dolly.

Threw $10 of gas in it and let it idle the whole hour home (figured it was worth it in case the trans was still good).
Obviously, it's the same red, but it is also the gray interior that I have. Unfortunately, I really can't use any interior parts. I already replaced my dash, and the reclining handles on the seats are broke. My buddy wanted a factory CD player, but the guy didn't have it. I'll be taking the driver's door (mine has holes in it for an extra trim piece below the body line like the Trailblazer/Bravada had), possibly the driver's door panel, the grill and lights (I already have projector headlights and turn signals with amber corners too), and maybe some other stuff (the engine if I part it out).
I haven't decided what I'm going to do with it yet. I'm either going to part it out and scrap the rest, fix the trans and drive/sell it, or demo it. I'd really like to fix the trans to learn how to and have a test-bed to test it on, then possibly still part it out and/or sell it. I probably won't demo it just because I'd rather see if anyone is interested in any parts.
It's basically going to sit for the winter and wait until spring. I'm going to try to drop the pan and refill it tomorrow just to see if it does anything (probably not, but it'll only cost $10 to do), but it's suppose to snow tomorrow so we'll see if it happens.
It really acts like the fluid exists the pump, then after it sits for only a couple minutes, it moves again. Any thoughts or ideas?
