Default 1967 Transmission Issues

Folks, I appreciate all the assistance I received related my backup lights and oil pressure issues. All is working well in those areas. Now I have a different issue. Lately my transmission appears to be slipping or slagging as I accelerate. I googled the symptom and everything I found states that the TH 350 doesn't have belts, what can be the issue?

As suggested, clutches need exchanging (trans overhaul) or low fluid level.

Do automatic transmissions have a clutch?

Yes, they do, one set for each gear.
As an auto trans upshifts, forced oil is channeled into the planetary gear hub pressing on a piston to 'clamp' clutches together making the unit turn as one.
When clutches disengaged, planetary gear turns as this gives a gear ratio, 1st, 2nd, 3rd gear.
Clamp via pressurized oil, a gearset becomes one, upshift to next gear has happened.


I had a friend's THM350 due for overhaul. The clutches were burnt so bad, they became one unit, so when trans upshifted to second gear, the vehicle came to a skidding stop.
