hurst shifter, saginaw 4speed shifting problems

i have a 79 Chevy c10 with a 350, Saginaw 4 speed and a Hurst shifter. i recently bought the truck. I was told there was a problem with the transmission and/or shifter. i pulled the tranny out, pulled the side cover and everything is in good shape. i installed new bushings on all the shift rods put the tranny back in and on the first drive i had some problems shifting in the gears. at a stop sign i attempted to shift into first but it wouldn't go. it was almost like it was stuck in 2 gears. after i was kinda rough with it it finally came out of gear. i drove it back to the house but was still having problems getting it into the correct gears. could somebody please point me in the right direction.

gettin closer

OK so i just crawled under and put a bolt in the shifter to hold the rods in the correct position. i had to adjust 3rd-4th gear rod about 8 turns to get it right. i had to adjust 1st-2nd gear rod 2 turns to get it right. now the problem im having is when i shift back to neutral from 4th sometimes it will try to stay in gear. Also it wont go into 1st from a stopped position i have to shift from 2nd to get it to go into 1st.

http://www.jegs.com/InstallationInst...0-373-3163.pdf
in the hurst info you can see the 1/4 in L tool

I had a T 10 4 speed behind a small block Ford that looked good inside but I still had shifting problems, then changed engines to a 401 buick, auto.

Its not in the shifter its the Saginaw trans (my opinion) they are notorious for this It needs refreshing a basic kit costs around 150 dollars if you have the ability to do it yourself. But if your paying a shop to do it, you may do better to find a good Super T 10 or Muncie M 22 or 21 they are much better transes! and a new saginaw runs about 800 dollars average!

The Hurst shifter for the Saganaw and installation kit has its own inherent problems Its just a crapy shifter when used with the adapter kit the stock saginaw shifter works better if not wore out and is easier to adjust.

I bet your slider, shift fork or the engagement teeth on the 1st gear are pretty worn. It'll need a rebuild. If you're on the east coast, I can recommend a few guys for parts

Has anyone considered the clutch may be dragging a bit. It sure will make one want to stay in gear as well as keep it from going into gear.

when i had the side cover off the shift forks looked good. although i probably should have measured them. the synchros looked worn but i thought they were probably still good. i was test shifting both ways. when it is not running it shifts a little smoother than when it is running. ill crawl under again and check my linkage again just to be sure. if i still cant get it figured out i guess ill pull the shifter out and take it apart and check for wear there. if it looks alright ill pull the tranny and check the clutch out. also i would like to thank all you guys for your help. much appreciation
