I have a 2001 with 35000 miles on it. I wound it up in 3rd and then backed off and shifted to 5th. It ground a little, but then went in to 5th. I went to shift to 6th and it would not go in. No grind, it just would not go in, even after I stopped.

The next day I'm going to take it in to get this checked out, I pulled hard into 6th and it did go in (not easily). So I'm driving and shifting from 5th to 6th a couple of times with out much trouble. Still feels a little notchy or clunky, but shifts OK. Rest of the gears a normal (like butter). Any ideas what happened???

 

Do you "skip shift" often? This is bad for the tranny and you are damaging the syncros. This habit may have contributed to the problems you are now experiencing with getting into certain gears.

BTW, "Woodwork" is Honda's main tech guy in Torrence, California. His dept. handles all mechanical issues to do with NSXs and S2000s.

 

Thanks for the link. (I did do a search, but didn't find that one) That sounds every much like what has happened to me. I will now 'try' not to skip shift again. I think I will have the transmission fluid changed to remove any debris that may cause additional problems.

 

Can't remember if it was mentioned later in that long thread, but I recall some saying that if you just shift it normally through the gears for a few days, it will get better and even back to the way it used to be.

 

This is what was said -

When the sleeve is moved when engaging a gear it must first compress a circular wire spring that rests in a groove between the synchro hub and the synchro. If any bit of debris gets under the spring it can get stuck there and prevent the spring from compressing enough to let the sleeve slip over it. If after some time the bit of debris works its way out then the gear will suddenly be restored.

This is what seems to have happened.

I may PM "Woodwork" to make sure that no long term damage will be done by not taking more aggressive action.

Thanks again.

 

Woodwork hasn't been seen around here for quite some time. He may not respond.

 

get a short shifter kit or new bushings i think?

 

And just how would those affect internal transmission operation?
