hurst/tranny.. what am i missing??
Ok... 77 with a munci 4 speed....hurst shifter#3216274/ 3306126....... I was having issues shifting into 1 and 3... Really rough/dry.....I tried adjusting it with no luck... Didn't matter if the car was running or not, same thing..... So I have pulled it all apart... I can easily move every gear forward and backwards with a wrench.... The shifter works fine too.. The only issue is I can't get it into reverse with the shifter bolted to the bench.... But 1-4 is smooth.... Thoughts? What am I missing?

Is it possible you have the linkage rods attached incorrectly or to the wrong side of the arms (on either the shifter or trans side)?
Seems odd that you are having issues on all 3 levers only in one (same) direction.
If you had a pic of how it looks installed (inside and under the car), we may see something obvious.

Well... Here's an interesting development.... I put the shifter back in... The linkage hits the cross member....???? It was shifting perfect until about 3 months ago... I know the shifter is back in the correct spot and the linkage is installed the same way... I bet this is the problem.. Maybe lost a bushing???

Losing a bushing on the shift rod wouldn't drop the linkage that low.
Are you sure the shifter is bolted to the shifter mounting pad correctly on the trans tail shaft and the mounting pad itself is mounted securely to the tail shaft?
Without seeing it, I can only guess it's that or your trans mount is worn so badly that the back of the trans is sitting low enough for the linkage to hit.

i didnt take the mounting plate off.. just the shifter... so i know its installed correctly.... its hitting where the shifter connects to the linkage that is hitting.... it has to be that transmission mount...

There really would be no other way for the linkage to hit the trans cross member otherwise..

Trans mounts from a Muncie to Auto are the same part number for the Turbo 350 but the Turbo 400 has a different part number.
You need to make sure you have the correct mount for your application.
Oh wait... You have a 77?
77's didn't come with Muncie 4-speeds from the factory so this must have been swapped later?
Do you have the 2 bolts in the trans and one (stud) in the cross member or is it still 2 up and 2 down for 77?

Did they swap it for the 74' and earlier dual exhaust style or is is the stock 77' single exhaust style?

Worst case, you may need to put a thin shim between the mount and the cross member to give you the required clearance.

Also check the two bolts on the hurst shifter housing that are use to set/limit the throw of the stick. It is set for 3rd and 4th gears but also limits 1st and 2nd. If you where having issues with 1 and 3 it could be this adjustment bolt.

The mount helped but did not fix it.. I can see the linkage rubbing on the crossmember now that I am looking for it... Here's a ?.... The bracket the the mount bolts it is on a pivot correct?

I believe there is some room for adjustment as far the the relation of the shifter body to the trans so you can make sure the shifter level is in the middle of the console opening when it's installed. It is some sort of pivot arrangement from what I can remember.
Is that what you are asking?
