very discouraged

[SnS C10]

well as some of you know, ive been doing a ton of work to my 64 c10 longbed straight six manual trans non power brake truck. Shortbed conversion, 77 c10 suspension disc brake upgrade, power steering upgrade conversion. 1999 vortec 350 and th350 auto trans. So yea lots of work to do all of this as you guys know. Ive had the engine in for awhile now and finally got it started up and running nicely 2 days ago. Got my nice new b&m quick silver shifter installed, power steering and power brakes working great. Go to shift into reverse....nothing. Drive....nothing. Ok, engine is fully warmed up, check trans fluid, its low. I fill to the top line, and run through the gear again. Nothing, acts like its in neutral in every gear. Next, i pulled both transmission cooler lines and ran the engine, through every gear, and it did not pump a single drop of trans fluid

looks like i need to pull the transmission out and have it checked. Very discouraging to get to the cusp of the truck moving on its own power and it not happen. This thing seems to fight me on whatever i do to it. nothing has gone smooth, it likes to fight me. I was given the trans by a good friend who said it was working fine. I filled the converter with fluid and seated it properly. Time to start pulling a trans out... Oh well, just thought id give an update
