98 sonoma manual trans problems

I was driving my pickup down the freeway today & all of a sudden when trying to shift into 5th gear, found it was missing! It will physically fall into position like a normal shift, but will not engage the gear. I also found that reverse will just kind of grind like it barely touches with the gear, but will not fall into place.... Has anyone had this problem? I can fix mostly anything on the truck, but I am curious if this is a major problem or can it be fixed by a fairly seasoned shadetree mechanic? thanks for any responses....

Sounds to me like it may be synchros.

Re: 98 sonoma manual trans problems

Before you get too crazy make sure that your fluid level is correct. If you need to top it off you'll need to get the special stuff from the dealer for the tranny.

If it's whining at all when you are in neutral it might be a pilot bearing going south. If that's the case you can replace just that but it might be better just replace the whole clutch, since you'll be tearing it all down anyway...

I've never really heard of the synchros going bad on these tranny's (assuming your '98 has the NV3500 like my old '98 Chevy did), but it is possible I guess.

Last I checked these boards still don't e-mail replies and I don't keep track here. So if there's a yay or nay reply I won't see it for a while. But good luck.
