Its not very often 5th wears out, who hard shifts into fifth.

Do you know if your lower gears have been replaced at all? Usually they would wear out much quicker.

Its actually very common. Most of the time its from people who don't check their fluid levels. They end up running it low and the top gears(5ths and 4ths) heat up due to a lack of adequate lubrication. So this creates scarring and makes it difficult to shift because the parts are no longer smooth and free. I have also just plain seen them worn out! People tend to rest their hand on the shifter in 5th gear while cruising. Well that will put some pressue on the insides and wear things out over time. Crack it open and check it out

 

just get it done @ a shop it's cheaper and less hassle

 

you guys say synchro mesh will help with the grinding? mine grinds into third sometimes. so im lookin for something to stop/slow that down before it gets worse?

 

Only thing the will stop it is to have it rebuilt. Either way it still has and issue, synchromesh just masks the problem.

 

yeah thats what i figured but i wanted to check and see if anyone had any ideas tho. thanks man

exactly

You can bandage a deep wound but sooner or later you are gonna have to stitch it up before it gets completly infected

 

i would try putting in the GM synchromesh friction moddified first....if it is a small grind, it should help it... if you have the the time and money though, just get it fixed.

 

Temporarily mask it

Getting a shop to do it is cheaper?

Anyhow, replace your syncro before you end up having to replace the gear. Using syncromesh or something similar is just going to cover it up....it won't fix it.

 

In my friends prelude we used 10-30 mobil 1 oil and added lucas to it. That pretty much took care of the problem temporarily
