Transmission identification
How can I tell which transmission I have?
I have a 2002 6-sp roadster. I am seeing references to to T56 and MN6 and others.
I am going to have to find a used transmission to install in the car and am not sure what to start searching for. It seems that the 1-2 synchro is badly worn...found out of course after buying the car about a month ago.
Thanks.

If you have a standard coupe or convertible, you have a MN6.
If you have a Z06, you have a MN12.
Both are a "T56" transmission, with different ratios.

Actually if you have a non Z06 that is stock you have a MM6. MN6 is the RPO code for a manual transmission which can be either a MM6 or M12. Either will bolt into your car without modification as long as it comes from a '97-'04.
