I have a 2007 Type-S with 34,XXX miles on it and no problems with transmission at all. However, I do change the ATF with Honda ATF every 15,000 miles or twice thus far. My general thoughts are that if the transmission was part of routine or OEM recommended service to begin with, there shouldn't be any abnormal problems with it over the course of its life. This excludes the know issues with the Acura '01-'03 TL transmissions that Acura had to issue a TSB and extended warranty on. Those were problematic and Acura did all it could to initially evade owning up to the problem. I know the Acura dealer and their master mechanic here well and his thoughts run along what I'm passing on here. After 2008 until the TLX with a dual clutch transmission came out, their were 'normal' with proper maintenance. However, the first couple of years of the TLX's new dual clutch tranny saw a return of mainly software related problems that were manifested as transmission hardware issues. Updating the software at the dealer solved most of these early issues (my mother had an early 4 cylinder TLX with constant problems initially).
