Harsh into second

JapesMooney · Post by **JapesMooney** » April 25th, 2006, 1:21 am

I'm noticing that I'm getting some harshness in my shift into second, [sometimes to the point of grinding if I rush the shift] and it's generally worse when it's first going. All other gears are fairly smooth. I replaced the tranny oil with MT 90 in the hope that would clear it up, but while it has improved it, it's still not great. I know what I think it might be, but I'd like to hear other peoples input. Suggestions for the next thing to try? Thanks for any suggestions.

sounds like 2nd gear synchromesh to me.

The first thing id do would be check the shift rod and make sure that its not bumping into anything like the heat shield or anything else, but i think i agree with boris.

There are a few things that can cause this, if your motor mounts are on thier way out they can produce a simliar affect as well though. I would suggest chanigng over to pennzoil's synchromesh. Its not cheap but it actually works fairly well and might cure your probelm.

torpedan,

I dunno what you mean by your comment (umm what). What's wrong with assuming it's the 1st/2nd syncro?[/quote]

Japesmooney,

If you know how to double clutch, try doing that. If the grinding stops when you double clutch, then it's most probably the syncro. That's also a cheap way of getting rid of the grinding, if you decide you don't wanna pay for the repairs.

Synchromesh is a product, its a lubricant. A synchro is a synchronizer, as in a gear. The sentace makes no sense.

Mine does that in the winter going into second when it's really cold. But once it is warmed up it is perfectly fine. I think it just needs better tranny fluid.

I know there's synchromesh lubricant but I'm pretty sure my sentence made sense... Our gearboxes are classified as synchromesh gearboxes, right? Meh who knows I might have screwed up, correct me if I'm wrong so that I don't keep using this term.
