Transmission passing gear keep either getting stuck or it dont work because the motor keep idling up in first gear
this could be relative to many things, however you should check a few things before asessing the possibilities. When you put the truck in gear from park, Drive (overdrive) Should be the third notch you come to. so your in park, pull down clunk you're in reverse, clunk you're in neutral, clunk, now you are in drive. If you dont feel/ hear four notches/ clunks, you should be in overdrive. If you take off and it over revs 1st ( you shouldn't see more than 15 mph before it shifts on a stock transmission unless your flooring it and taking off fast) and then hard shifts to second gear, progresses to third gear normally, but wont progress into overdrive, it may be related to your vaccum advance, your shift linkage, or even possibly your timing. From the sounds of it, I would say vaccum advance is the likely cause, if it is otherwise in stock condition. If this is the case it could be as simple as reconnecting a vacum hose to the distributor. Should be to the left hand side of the cap, between the cap and intake manifold as you are looking at the firewall.
