I've been searching for a couple hours now and keep finding conflicting information. First thing - i'm getting a crunch when shifting at higher speeds from 1 to 2 in my 1990 5 speed - occasionally, sitting at a red light, rowing through the gears, it'll crunch then as well. I don't know all that much about transmission internals(i couldn't identify jack ~~~~ if you showed me a cutaway, i just have a very basic conceptual understanding of how they work). My guess/assumption would be that a synchro is starting to wear out. I don't think it's a clutch or slave cylinder issue, since no other gears present a problem. Anyway, on to my question.
Before paying out the ~~~ for a transmission teardown and rebuild, I'd like to just jack up the car and check for low transmission fluid and give her a top up to see if that would help. I know the factory manual says add the ford friction modifier, but is that to make it have LESS friction or to have MORE friction? I can't figure it out based on my searching of these forums. From my understanding of what's going on inside the transmission, I would think that I'd want MORE friction so the gears and synchro and whatever all clunk together more reliably than they are. Can one of you old timers(sorry but it's true) shed some light on my question for me?
