Engine & Gearbox 3rd gear syncro needs replaced on 2005 Accord Type-S

    3rd gear has been crunching for a few weeks now, Honda main dealer has now diagnosed the syncro is needing replaced.

    Can someone please explain exactly what needs doing and roughly how many hours it would take to do it, I've been told
    the syncro's come in pairs so I'm guessing it would make sense to replace them both, would it be 3rd & 4th ?

    Also price of the parts required would be useful.

    Many thanks
    Andy

    I probably would get a secondhand box. Must be a lot cheaper than repairing current one.

    Oh dear - significant labour in getting this done. As it's pretty much the same effort as a clutch change (gearbox has got to come out). Instead of a dealer how about a specialist? A 2nd hand box is an option, but this could have been abused, etc?

    What mileage is on the car and is it the 2.4 TypeS or 2.0 TypeS (I think that was 2006+)

    Not just removing the gearbox it's the time to strip it and rebuild also. Just doesn't seem worth it. The gearboxes are not a common failure issue, so a secondhand box is a risk but should be ok.

    Fair point. Near me there's a gearbox specialist doing strips and rebuilds of Honda gearboxes for 1000 euro all in. Including removal of the box from the car. They give a 6 month warranty too .

    They've done a few Type-Rs already

    It's the 2.4 Type-S, I had thought about trying to get a second hand gearbox but dismissed it due to it being too risky.

    Although the car is 7 years old it's only done just over 50k, I'll talk to the Honda dealer on Monday to find out what costs may be involved
    and then decide from there.

    Cheers Guys

    Strange to find that sort of damage on a accord must have had a hard 50k miles.

    Pre facelift ATR's were notorious for 5th gear synchro failing and losing the ability to select reverse .I know it doesn't relate to this car but Honda gearboxes seem to be a weak point in the past in various models.

    Worth mentioning oil here, not sure on Honda but would suspect the norm that a MT gear oil is used conforming to a GL4 spec, putting a GL5 oil in a box that should have a GL4 in will destroy the baulk (synchro) rings. I know this is the case with Toyota and many others, dealers sometimes use the latest spec oils thinking they are a upgrade on the previously grade, where they are a different oil altogether. If the box use,s steel synchro rings a GL 5 oil will be ok. Check with your handbook.

    I had my original box repaired by Honda and same fault appeared 12 months later and less than 5k miles.not happy.tried m factory ones which also gave in,eventually tried a different synchro out of another accord box that was more beefier,and it has lasted well.

    Guys let make a direct distinction here the 7th Generation gear box DOES not have mass scale issue as the CH1 or other Hondas. Infact its the most reliable gearbox for a very long time , so lets not tar the 7th Generation with the same brush here. The OP with the problem is an isolated incident and it cold be attributed to the driver and not a techinican issue. I haven't ye seen one gearbox diesel or manual with engineering faults but seen loads of abused gearboxes.

    Good to hear you've resolved your issue.

    Could you please explain what you mean by "out of another Accord that was beefier" ?

    How was and what was beefier ?

    can't say much about the gearbox as I don't work on Honda, My advise once the box is changed or rebuilt is to use the correct oil,not the viscosity but the type, sounds like you say a case of obbuse weather because the wrong oil has been used or bad driving.

    Totally agree with you ichiban,just stating that hondas gearboxes aren't infallible, as for beefier,the one in the CH1 was very flimsy,the one I changed to wasmore substantial all over but mainly around the teeth area, but to me the biggest cause of wear and tear is not changing the oil,as most times the oil doesn't get changed for years,I now change mine evey service or at least yearly.

    I've had the car just over 5 years (10k on the clock when I bought it) and I definitely haven't been harsh on the gearbox. So must have been something else, it ended up costing me just short of £1200 to get fixed (Ouch) but as it's the only issue I've ever had with the car I put it down to shear bad luck.

    Cheers

    How often has the gearbox oil been changed?

    There's plenty of possible causes.

    What were the seals like ? Worn seals could allow some of the oil to seep away and lead to low oil in the gearbox.

    Conversely an overfilled gearbox oil leads to excess heat generated, which could lead to eventual damage to gearbox.

    Not fully disengaging clutch either due to driver error or mechanical issue.

    Incorrect construction, if any of the many components that sit on the shaft are even slightly misaligned at construction, this could lead to premature failure.

    A component not within spec or up to quality.

    At the end of the day a gearbox is a mechanical device, is prone to failure as any mechanical device is.

    I never really investigated any further to find out why the syncro failed, I was just glad to get it fixed and put it down to bad luck. The car has been serviced by the main dealer every 12 months since I've owned it, I assume (if the service schedule requires the gearbox oil to be changed) the oil has been changed at some stage during the 6 years that I've had it. Running really smooth now :Smile:, definitely keep an eye on things from now on and ask more questions when the service is due.

    Cheers
