310-8 transmission won't pull

Question edited for clarity.
Question moved to model category.

Transmission pump possibly it says in the link. You need a transmission expert.

Check the Transmission Cable. It could be half torn Transmission cable. You may have to replace the cable then

I would guess that something inside of the transmission has failed and there is no longer a mechanical connection between the motor and the drive axles regardless of what gear you attempt to move in.[sheared splines, broken planetary, etc.] Often when this happens you won't hear any kind of noise because of the failed parts being inside the transmission case...instead the car just won't go anymore. You could have a CV drive axle joint that has failed but generally they will make some noticable rattling or grinding noise as they churn away when you try to go forward or reverse. If something has failed inside of the transmission then the transmission will need to be removed and repaired. It if is just a drive axle joint that has failed then that can be replaced without doing anything to the transmission. Hope this helps and good luck!

Something has sheared. Is there a pin on the distributor drive gear, are the gears on the cam and dist. shaft perfect / no flat spots at all, is there a keyway or key on the crank or cam gears that has sheared? Must be a weak point that was slipping somewhere.

If the fluid level is correct and it will not go into gear, you need a mechanic. Have the car towed to a transmission shop. It is possible that your flexplate has sheared loose from the engine and your transmission is OK (caused by shifting into gear at high revs). Worse case, you need your transmission rebuilt.
Sorry, but this could be expensive.

you can drill the remainder of the bolt, tap it with a left hand thread, then insert a left thread bolt (smaller) and as you tighten the left hand thread counter clockwise it will loosen the right hand thread.

there or after market replacement boots that are split the length of the axie you cut off the old boot replace with new with out removing axle

i can't change into 2nd,4th and reverse gears. i think its a gear lever cable not sure doe any ideas?

Dear javatrader: There are very few solutions to this problem. The fact that you had mentioned 5th & Reverse, tells me that you problem is has two possibilities. Both relate to the same component.
The shift fork for Fifth gear and reverse are the same as well as the hub which the fork fits over.
When you Move the stick shift, it moves one of 3 rails in the transmission of which one is 5th and reverse. The hub is what locks the transmission in gear. The gears are what are referred to as synchromesh. This means that when you shift from gear to gear, it makes it possible to easily make the transition without the gears grinding while the car is in motion. The synchros are in fact, kind of a "BRAKE" for the gears so that when you go to shift into that gear, the synchronizing ring, slows the gear down enough to match the speed of the counter gear allowing it to engage with it, without grinding. As the hub slides into gear, there are spring loaded "KEYS" which are small pieces of steel about 1/2 inch long, 1/4 inch thick and 1/4 inch wide with a little hump in them to push up into a small cavity machined into the hub when it slides over it, thus locking the gear into place until you pull the stick to move it out of place. If a key pops out, it could cause the gear to stick, not allowing you to pull the hub back because the key has popped out at an angle which prohibits the hub from sliding over it.
Another possible senario: The fork is secured to the shift rail with a part called a "Roll pin". If this part shears, the car will be stick in what ever gear it was in at the time the pin sheared. If the pin shears, the stick will still move out of 5th gear position but the transmission won't.
This problem, unfortunately is not one a layman can fix. This is best left to a professional.
Good luck......If you are pleased with my answer, please write in, that you are satisfied with my answer. I am new in this "FIXYA" group and need more people responding to work my way up the ranks.
