Lost reverse, need help finding it. 727

Trailbeast is right, a trans clutch or band that has actually slipped won’t last a Few seconds before it wants to weld itself to the contact surface. Had a front clutch that slipped and fused 2 clutches and 3 steels together. Vehicle would move foreword in neutral. A band will just smoke itself til it hits metal or just wont engage anymore. Smoke will pour from the dipstick tube if you can actually slip friction material. What most people feel as a “slip” is really just bad shift overlap, slow engagement, etc. Bands being too tight or loose. Or the wrong ratio levers. The overrunning clutch can slip and cause problems as the cams and springs wear out.
