Engine / Gearbox Noise

Postby shadowf1 » Sun Jun 08, 2014 9:28 am



I recently picked up my first Goldwing. It's a 1990 GL1500.
I absolutely love the bike but unfortunately I just started having a problem with it.
It is a high mileage bike with 137,000 on her but she has always been taken care of and I have all of the service records for the bike going back to when it was brand new and it still is in great shape.

The problem I am having is an intermittent metallic grinding noise coming from the gearbox area.
After researching online and speaking to several of the more knowledgeable people in my local GWRRA Chapter we are fairly certain that it is the dreaded 4th / 5th gear shift fork that is worn out and rattling. (It also started to shift hard and grind a bit when going into 4th or 5th)

My question is can anybody steer me towards a shop in the Northern NJ tri state area that can tackle a job like this?
I am a competent mechanic but I don't have the recourses and time to take on a job of this magnitude.
I have contacted my local Honda dealer and they were not to enthused to take it either.

My other alternative would be to swap the power plant with a newer model. What year did Honda finally correct this problem?

Thank you,

You do not want to fix this. Parts are around $600, and labor is around $2,000, depending on the shop. It's a LOT of work. Decent used replacement engines can be had for around $500 or so, you want to get a 1997 or newer engine, as they have the stronger Valkyrie transmission in them.

Oh Boy:( I'm the second owner of a '88 GL1500 with a lil bit over 40;000 miles on the clock.Even after installing a Pivot shift,i still get a disheartening crunch in 2nd and 4th gear no matter how slow i shift.Whats the average life span on these trannies? The motor is in awesome shape and has a compression ratio of 140-150lbs.and gives about 49 mpg.would really hate to give it up after trans.fails.???Any ideas?

You never want to slow a shift, firm only. That said these trans are a little clunky shifting by nature.

The most important aspect of shifting would be a healthy clutch hydraulic system. Worn levers, bushings, old/air bound fluid and master/slave issues are by far the most common easily fixed problems.

Slow shifts also allow the RPM's to drop too much when catching the next gear, hold a slight bit of throttle so R's don't drop much more than 3-400 R's at time of upshift.

For the amount of 1500's that were sold and still on the road the tranny failures really are few and far between even on the early ones.Sold my 89 last summer with approx. 120 k miles on it and it worked perfect.Truth be told there are probably more 1800 tranny failures if you check around.There's a guy in Florida that pretty much makes a living fixing 1800 trannies.


If I'da known it would last this long,I'da taken better care of it.
