If not the floorboard is partially releaseing the clutch. If that is the problem get under the truck with 2 3/4 open end wrenches & adjust the nuts on the clutch link so you have about 1/2 in. free play at the pedal. If that's not the not the problem you need a new clutch. If it is getting oil on it you will need to take care of that also.

Is this the same issue or similar? should I be looking at something different all together? 1950 3100, 4 spd trans. I believe the transmission is a 1952. The other gears seem to work fine, though it seemed I almost had to be at a complete stop to shift down into 2nd but that has happened off and on in the past so I'm not sure its related. | | | | | Joined: Dec 2006 Posts: 113 Shop Shark | | Shop Shark Joined: Dec 2006 Posts: 113 | I should note that if I let the clutch out and push back in between 3rd and 4th gears it goes smoothly.

In your next post you mentioned letting the clutch out in between the shift. This is called double clutching. It was nessesary back before they had syncros in them.

And I always called it double clutching but someone corrected me once and said there was more to double clutching than that. Can't recall what he tried to explain to me but just in case, I avoid using that term when asking for advice from guys that know more than me. I want to be as accurate as I can. | | |
