Snap Ring Range Tranny # 3664

[davidl78]

Hey guys,

I've read through the FAQ over and over on the Snap Ring section. After reading it it seems even if the trans number falls within the range I may be ok because the manufacturing machine cuts a perfect one and then it gets progressively worse until the machine is recalibrated. Any owners out there that had a problem or should I say has had NO problems that has a tranny number close to mine, 3664?

I've talked to my dealership about preventive measure and they're take is they will not goodwill it unless it does snap and i ruin the transmission and it would be partial. Should I go ahead and install short gears or R&P and ask Acura to give me a new transmission case since the I was already paying for the labor to do the gear changes? How much extra will it cost and do you think its worth it or should I just let it ride and see what happens?

Just realizing my car is in the range I'm concerned and wanted to ask other owners with their experiences how I should approach thte situation in the most cost effective way possible. Just put in short gears (whats the benefit of short gears anyways?) or just let it ride out and hope for the best? My NSX has close to 80k miles with no problems yet. My dealer here in Jacksonville, FL (orange park) seems to think there is no problem unless it presents itself and won't goodwill a prevention repair so I guess its up to me to figure this out. None of the dealerships in the area haven't really given me the impression that they have great experience with a snap ring failure. Any thoughts and opinions would be more than greatly appreciated. Thanks.

Check out the FAQ section on "Gears" under the Performance heading.

contact american acura and ask them if you pay the labour will they supply parts. they may look at the fact that you have no other damage and it may cost them less$. don't tell them that you plan to change gears. that can between you and the dealer.

From my understanding they won't goodwill anything unless maybe if you were the first owner and with low mileage.

Don't worry about it, it would have likely failed by now. The car is 14 years old, how long did you want them to do "goodwill"?

If you are going to worry about it: just get a new case ($600) and it is a DONE DEAL.

The $600 is well worth it, even if there is nothing wrong with your transmission...it will pay off in about 3 months because you will be free to worry about more important things.

Not true, as noted here. The snap ring can fail at any mileage. As Chris insightfully notes, this is because the degree by which the case was machined improperly varies.

I agree. If you're having transmission work done anyway (such as the installation of non-stock gears or a clutch replacement) then you're basically just looking at the cost of the snap ring and the case, $655 at Dali Racing or slightly higher at your dealer. Not enough money to get all worked up about.

I just said it was unlikely. It is also extremely unlikely that Acura would goodwill this late in the game and/or with 80K miles.

He has already cut his odds by 50% for a failure, maybe has a 5% chance of goodwill and the actual chance he did get a bad case (1:5?). It has been a while since my finite mathmatics...

So my position is: Forget about it. If not, get a new housing and be done with it.

/Personally, I would spend the money.

I agree. As noted previously, here and in other posts.

goodwill is usually given if you are the first owner. my snapring broke at 57,000 km last year(before I purchased) and was not goodwilled. I know of 2 other owners who got goodwill parts only and 1 was first owner the other was not. I'd try what do you have to loose.
