Ok, I have posted about this problem before and got some recommendations from adjusting the shift linkage to the type of shoes I'm wearing (??). Well, I have adjusted the linkage every which way possible with no improvement in the bad up-shifting. I've had a number of 1st Editions(6) and never had one like this. There has got to be something else causing the hard upshifting. I've just got in a complete clutch rebuild kit from Buckeye and am prepared to install new friction plates, new diaphram spring, etc., but I don't think that will help either. I am now thinking I may have a dowel pin problem (loose and/or just not fitting properly) in the shift cam. Does anyone think replacing part 6 and 8 in the microfiche will help?
Just in case it comes up....rebuilt the m/c, installed new slave and no air in the line.
