Not as per the 2016 rule book. In Stock the trans rules (For use of forward gears) does not match that of SS for the sticks. BUT for Autos in S, as you know, you can run a metric behind a PG combo etc. But, it looks like until someone ask the NHRA with a letter will allow a 4sp to replace a 3sp maual in stock.

Sorry again Mark.
