NSX NA1 Snap Ring parts

[Fantiga1974]

Dear All,

Please if you can kindly support me to confirm which material is required to fix the snap ring issue. Is it only the new case ITEM 5 shown in the attached drawing? Is there any other material to be considered?
Don't hesitate to let me know if I am missing something, I just got my NSX and the serial is affected, I don't want to face a possible failure and I plan to get this issue solved.


Thanks again for your support.

You must replace the transmission case (#5 in your diagram). I also like to replace the snap ring itself (90602-PR8-000).

Also, you may need to select a new differential shim (starting at 41481-PR8-000) to account for the new case. Your mechanic should follow the process on Page 15-12 to 13 of the service manual to select the proper shim for bearing preload.

Hi Honcho, I really thank you for this information.

I recommend you engrave the new case with the invoice number and date of purchase so that everyone knows that it is a updated one. Get it done at a trophy shop, it will be a $20k-$30K question in the near futue.

There is no great way to determine if a case has been replaced. Though it seems if the casing has a black ink stamped number it's a good indicator of an updated case.

I don't recommend that you actually install the casing. The odds are good that everything is good. You'll know when it goes...
