Does your 2001 CL-S have updated PCM P/N:

37820-PGE-305RM
or
37820-PGE-315RM

?

 

I inquired with Acura client services as to which PCM P/N is correct for my 2001 CL-S, as TSB 03-017 stated it should be 37820-PGE-305RM, but I had 37820-PGE-315RM installed, as listed on my service invoice for my replacement tranny. They stated that 37820-PGE-315RM supercedes the 37820-PGE-305RM and that the 305RM unit was an interim solution, as they figured out the tranny failure issues.

So to summarize, the 37820-PGE-315RM is the latest revision.

They should really update the TSB to reflect this change.
