Probably not

Only the L67 Eprom carries the code for that input line. And all L67'* came with the shift button.

Remember that the L67 by default is limited to a lower shift point unless you select performance shift, in which case it will shift like the L27.

yup the L27 has the higher shift, programmed stock...so in other words the L27 is in Perf. mode 100% of the time

At least in a Series I, the Normal button will "retard" the shifting behavior of an L27. And I still feel that a L67 is programmed with a more aggresive Perform shift than an L27 has, after driving my car and a few L27s.

So what'* the difference between a car that has traction control and one that doesn't? Just the PCM?

The PCM and the PMV in your case. The doohicky under your airbox with all the brake lines.

For your year, it uses applied braking and retarded engine timing.

For earlier years, the PCM has nothing to do with it (97-95).

Keep in mind those switches can be used for other purposes. And it has been done before.

As gimmicky as it is, I don't know why, but everyone loves it when I hit my TC button... But it is fun to hit a button and listen to 'er fire up.
