Transmission advice, Hard 4th gear Options

[vertigo]

'73 stock except dellorto 40's. I am having trouble shifting into 4th gear. This started yesterday. When shifting up through gears all is ok until 4th, it is very hard to get into gear unless go to 5th first. Then it will go in easy. If just 'forced' into 4th sometimes there is a grind and is hard to shift to another gear also. At this time it is intermittent as it will work perfectly about half the time, but I know something is amiss but not sure what. Anyone run into this before? Suggestions, ideas, or experiences on how to solve appreciated.

They are at either end of the shift rod. One is under a plastic dust boot held on by a clamp at the transmission end. The other is under the dust boot on the firewall end. Both screws are 4mm hex tapered screws with the tapered part fitting in a notch in the shift rod. ------- Changing tranny fluid is good to do on a regular basis from a maintenance perspective. As for shifting into first when the tranny is warm. Have you tried shifting into second then first or from third to first. Assuming you are shifting into first from a stop.

yup, picked that up from the archives. The "spindown" trick from 2/3 works great until its been running for 1+ hours and then it starts to get cranky.

I just got done going over the engine, need to do a full bore tranny check next....
