One possibility is (believe it or not) the solder leads on your oem odometer! They may need to be re-flowed. Either that or just bridge the speed sensor inpuy & output from the odo cluster harness plug. In short, if the solder leads are cracked, the oem ecu doesn't get a speed sensor signal from the transmission, which causes an artificial rev limit....usually at about 5k... This isn't a for-sure diagnosis, just one possibility...

As far as I know, the air conditioning system does not have an amplifier.

Thanks for posting back. Why were the bad rings limiting your rpm? Was it smoking at all (via the exhaust)? Are you sure this is the (only) problem?
