Transmission issue

Postby 702scottc » Sun Jul 24, 2016 3:20 pm



I have read here before that the shift fork in the earlier 1500's had an issue causing grinding noise? I think my 1990 has this issue. Developed riding home from the coast yesterday. 1st, 2nd, and 3rd are making a lot of gear grinding noise and doesn't stop even with the clutch engaged until you stop. 4th and 5th seem fine. I ended up leaving the bike at a friends in Minden,Nv and having my daughter get me and drive me home. Sucks. This thing went 145,000 miles with no issues then bam. What year did Honda make the upgrades that eliminated this issue? Want to make sure I get a newer engine assy.

I would check the operation of your clutch first, might need a slave cylinder rebuild? imho - would be a cheaper option as well.

The issue was for 4th gear only and was 'fixed" in late 96 but really 97 models and on all had the valleryie tranny that was the fix..Not a grinding issue more one couldn't shift into fourth so most just skipped to 5th as it was easier to get a replacement engine than fix the tranny.
HAD LOTS OF GOLDWING 75-83
NOW INTO 1500'S..RIDING A 1998 SE

FAIR WINDS,

It shifts fine into 4th and 5th. Only pops in 1-3rd. Also changing angle of the engine, grinds heading downhill. I saw a YouTube video doing a search and it shows turning the output shaft while shifting gears making the noise. It isn't really a grinding noise, more like popping noise trying to engage the gears. Shows a lot of play in the shift fork and the back and forth movement on the shaft in the video. Either way, the fix is to split the case and replace the shift fork along with the synchro assy. Could have been too many years with a sloppy shift lever? I installed the pivot brace right after I got the bike, I also put floorboards and a heel toe setup. Always shifted nice with the board setup .

I think if I can line up a 1998 engine I'll swap it out, should have all the fixes for the trans issue.

Update: rented a trailer and drove to Carson City and brought it home Friday evening after work. Seems worse after sitting for a week. Wouldn't roll backwards even with the clutch released, had to keep bumping it forward then roll back a bit. A lot more noise now as well even in neutral, ugly sounding driving on the trailer. I think a bearing came apart on th main shaft. Doesn't matter, I'm replacing the engine once it cools down.
I have been looking at a 2006 at the Honda dealer, tempting.. If mine was running I might use it for the down payment. Useless as it is.. Maybe someone will come along and offer decent money for it as a parts bike? Wishful thinking.. lol.

I have read that a lot of people have had shifting troubles with heel/toe setups, and many have reverted to standard controls as a result. Maybe try it with stock shifter, to see if that helps?

I appreciate the input, the heel toe setup didn't cause this. It happened abruptly and was shifting just fine. The floor board setup had only been on it a few weeks. It really sounds like a bearing failed. Either way the engine is toast and not worth the parts to split the case. Easier to swap it out. I'm contemplating just selling it as a project or parts bike and buying a newer bike. I've had a lot of fun on it and put some great miles on it, maybe just time to move on...

I`m sure stripped drive splines would cause the noise if the bike where moving but it makes the clunking and banging noise when its idling in neutral not moving.

I'm not an engine guy, but from reading, it sounds like access to the clutch and plates is a reasonable job. It might be worth a look at the clutch plates to see if something disintegrated in there, and may be repairable. It certainly sounds like something came apart, and that something might be glaringly obvious on inspection. It doesn't sound like bearings to me. They would normally give a more advanced warning, and I can't picture a failure, short of balls exiting the races, which would cause the noise you describe.

Your comment: "Wouldn't roll backwards even with the clutch released, had to keep bumping it forward then roll back a bit.", is what lead me to make the suggestion.
