If you are in the range w/low miles talk to acura about having the job done. They are more willing than most people think, the service manager at your dealership would be the one to make the call to acura. Sometimes some negotiation on your part might be necessary, but regardless of age and ownership status, they have performed preventive maintainance at 100%. It may help to tell your service manager that if he can get you covered by acura for the snap ring that you would go ahead with a major service? Sometimes the respect that courtesy. Note that worst case, assuming you have not failed yet the whole job is around $2200 (labor incl~800). The tranny housing is the big cost at ~$900 for the part.
