I put the rear wheels on jack stands, started the truck, put it in first gear and held the clutch pedal down with a stick cut to length. With that done the rear wheels did not turn on their own, and I could easily rotate them either way. If that check means anything, then I did not find evidence of the clutch not releasing.
With my overdrive transmission's free wheeling feature, I can shift to any forward gear without releasing the clutch at all. When I'm not accelerating with the pedal, the engine is always at idle when the overdrive is not engaged, so I learn that the transmission drops into gear only when the road speed rev matches engine idle speed. When the overdrive is engaged, I still need two or three stabs to get shifted into a gear. That could also be at rev match speed, but I do not yet know the speed of matching for 2nd OD or for 3rd OD.
Too many words. Sorry, I am not good with them. Also, for now I have time to babble words but no time to take the transmission out.
The synchronizers are new, so my new guess is that maybe they need to be worn in. I'm happy driving the truck and am used to stab, stab, stab for every shift.
Does that seem to be a reasonable idea?
Thanks!
