I had my LS tranny on my 1995 Integra Special Edition exchanged with a GS-R transmission and a few odd things have happened since. My speedometer doesn't work, but the miles are still being counted. The RPM, gas, and temperature gauges all work, but still nothing from the speedometer. Also, after driving for a little bit, the check engine light comes on and stays on until I turn off the car. Lastly, the transmission makes a humming noise while driving. It also does it sometimes in idle. Any help would be greatly appreciated.
