Dang it. 26/27 engine. When pushing down on the low/high pedal, only two of the three clutch push ring pins push out against the driven plate fingers. It will make me cry if I have to tear the tranny down.
Could the disk be varnished together only on the one side? Fat chance.
Could the disk have worn into the drum causing grooves for the disk to get stuck on, thus the drum will have to come out and have to be smoothed allowing the disk to slid? I once rebuilt a tranny where the large disk wore grooves into the drum but Mac's sold steel caps to repair the drum.
Either way the tranny is to be torn down.
Should I get a box of kleenex out?
Tyrom Thomas; Are you sure that you have a 26'27 push ring? They are different you know.
Would you please elaborate on the difference between the rings. Also if you put a pre-26 ring in a 26 tranny what symptoms would you expect?

I think I can answer this one from personal experience.
The 26-7 push ring has smaller diameter dowels. The earlier push ring will fit but if the holes in the driving plate are correctly sized, the push ring will bind in the driving plate and not release. In the engine I looked at, the clutch pack was always compressed and would not release into neutral. We had to remove the pan and swap the ring for the small dowel version.
Tom your experience could prove correct again. This is a wide brake band tranny thus 26/27. I bought the car not running. However I was under the impression it was driven before parked.
While looking into the tranny with top cover off and working the high/low pedal here is what I saw in regards to the three ring pins. One pin appeared to fully extend through its hole, one pin would only partly extended through its hole and appeared to bind. The third pin did not appear to extend at all through its hole. I rocked the crank back and forth to see if that would loosen any stuck disk. No change.
One more thing, the hole where the pin did expend through, I thought appeared to show signs of distress of having something forced through it. Make sense?
So from what you wrote, I take, the push ring could likely be a Pre-26/27 ring with a larger diameter dowel trying to mate up with a 26/27 drive plate with smaller diameter holes. Thus I need to replace the push ring with a 26/27 ring. OR in your opinion, can or would you advise against, drilling the plate holes larger to conform to the larger pin?
Thank you for your help.
Often due to lack of engine lubrication maintenance, the clutch plates/push ring hang up and can cause the holes in the driven plate to be quite worn. The mounting bolt pattern between the '26-'27 & '25 and earlier brake drum to driven plate is also slightly different.
Having to remove the driven plate to oversize drill the holes - wouldn't it be just simpler to replace the push ring with the correct one ? I have some available, if need be.
