3rd gear, i think shes going slowly Options

[speedfeen]

well i am mechanically inclined BUT remember i do autobody not mechanical lol





SO heres the story


Your driving, your going faster than 50km/h and u go to shift into 3rd and it grinds bad.....you do it when your going slower it doesnt do that....and well lets just say that more than once i go to ds into 3rd and it doesnt wanna go in.......


syncro? transmission? i know its easier to guess at what it is instead of seeing it but what do you guys think it is? just because it will do it sometimes and not other times im thinkin it may be the syncro....


ideas..

[speedfeen]

wholly fast freakin reply

no actually while i think about it the tranny fluid hasnt been changed, get some and throw some lucas in it....wouldnt hurt any

Changing it's a good idea, but don't use Lucas, it will thicken your oil, to stop the synchros from grinding you want to thin it.
That's what the synchromesh will do, thin it.
The GM stuff Mike E is talking about is the same stuff, just in a different bottle and more expensive.
I would suggest you do half and half or less [no more than half synchromesh], thin is better for the synchros, but thick is better for the gears. Since you live in Canada, 75W 90 is best. The synchromesh will mix with gear oil fine.

It only comes in one grade, what you see in the pic.

However, I would also suggest you shift at a bit higher engine speed. The snychros job is to match gear speeds, but you can help it by shifting in the right engine speed range [sounds like you're shifting a bit to low].
Less work for the synchros [they're metal brakes in your trans] means they won't wear out or break as soon.

I don't think I've ever heard this one before

Yeah, I mixed syncromesh with the regular 75W90 gear oil when I did mine. It takes about 3 quarts to fill the gearbox, so I bought 2 quarts of syncromech and 1 quart of regular gear oil. I live in southern california though.
