Nhra releases 2017 rule book amendments

Shifting should be a function of the driver. No assisting devices whatsoever. The same for everybody. Just my .02

If you need assistance shifting a 2 or 3 speed automatic you probably shouldn't be racing. Now when is Elegal-shift going away in stock?

Ed,
We could never figure out how or why they ever let some automatic cars have an electronic 1-2 shift.

By the name automatic transmission it should not take any function of the driver or it would be a manual transmission.
A true automatic you just put it in drive and go.

Let's not get too carried away here. Governors in automatics were OEM items, long before TA or ratchet shifters were around.

Mark, since you work with automatics all the time, I have a question for you. Is there a limit as to when an automatic trans can be made to shift by itself?

Most governors , or auto 1-2 shifts are based on output shaft rpm . Electronic shifts are based on engine speed . The difference is on good weather days a governor shift will appear to shift at a higher rpm , due to converter slip . Electronic shifts will shift at the same rpm regardless of the weather . Might be a problem trying to dial in a car if the weather changes during eliminations .

I bracket raced an automatic for years and tuned the shift points with the governor.
Just put it in D ....and it worked fantastic... shifted dead on every time on target.

My IHRA Pure Stocker has the electronic auto and after I installed the Baumann shift kit, it automatically shifts dead on @ 5,300 every pass, every gear

Does your transmission have a governor ? When I raced Pure Stock we had to run the stock 13" converter , which was pretty tight , so there was not much slip in the converter at the shift point . Has the Pure Stock rules been changed , so it allows a loose converter ?
