S.O.S. 833 pops out of 3rd without load.

thinking more about this the 3rd gear synchro is MOST likely bad-- this is a classic symptom of a worn synchro---same symptoms in any make of trans if the synchro is bad when either decelerating or just coasting it will jump out of gear what ever gear it is in at that time ---comp

Yes, your correct. However every part in this transmission is brand new with the exception of the shifter fork and side cover.

Well try the fork and side cover see if that works if not look at the 3rd gear synchro next--about the cover look at the hole the shifter fork goes thru see if it is wallowed out from use and check the fork to for excessive wear---are both forks the same if so reverse their positions swap one for the other see if that cures it--I'm still saying synchro is messed up some way

I'll try all your sugestion's tomorrow. Thanks a ton.

It's most likely the fork, Driving around with your hand on the shifter wears them out.

When you have the cover off , by hand engage 3rd gear synchro, to see if it goes fully onto the speed gear could have a thrust washer or some other issue preventing full engagement. I agree a worn fork can cause this should be easy to see, measure the fork pad area then the synchro slot width,should be maybe .060-.100 clearence would be my guess. Also how is the fork attached to rail, could be a sheared pin or set bolt. All guesses but hope you find it. Joe

Jerry,

Check the 3-4 slider, when you look at the splines, they need to be straight not hour glass shaped. Could be the syncro but remember its purpose is to slow the gear just enough to make the gear change. Also take a look at the pilot bushing, a worn one will allow the imput to walk around, although this usally a high gear issue.

Thanks for the offer. Are you Herb's son? I just built a motor using Herb's new set of spare 440 .060" over Venolia piston's from his 69 Bee. I plan on asking Herb to signature the box at this year's Mopars in the Park in MN.
