One problem related to automatic transmission control module has been reported for the 1997 Acura CL. The most recently reported issues are listed below.
Malfunction indicator light came on. Dealer informed me that the primary control module for the transmission had failed. I will have to pay for the tests to isolate problem an for labor to repair. Acura will replace the pcm as 'goodwill' but as maintanance was done per Acura recommendations this problem should have been caught.
