Automatic trans shifting

[Alan Roehrich]

In Stock Eliminator, cars originally equipped with automatic transmissions that were shifted electronically by the computer as delivered from the factory can use "E-shift" systems, even on transmissions that were not original to the car, and did not originally have "E-shift". So a late model EFI car can use "E-shift", but an older carburetor equipped car cannot. Some older cars are equipped with "auto 1-2" valve bodies. Those cars leave the starting line with the shifter in 2nd, but the car leaves in 1st, then shifts to 2nd at a pre set RPM. The "auto 1-2" feature is controlled by the governor and the vacuum modulator in most cases.

I think paul forte at Turbo Action lobbied to make it legal for the older cars but got shot down I think if they can have we should too C/sa

My Opinion: Stock trans with OEM electric shift is OK unmodified. Otherwise, all transmission shift upgrades should be driver activated. It's called racing, not programming for Gods sake.

What about a stock 727 ? No plates or vb just put it in drive and go.

I am not a Mopar racer but I doubt a stock 727 trans will shift automatically at 6500 rpm or so without modifications. Most of the older OE trans shift far too low in the rpm range for use with a stocker camshaft.

I wonder if Helms, Hughes, Waldo and the rest had auto shift.

I have a turbo 400 that has the modulator and weights set up so that it will shift at 5800 just putting it in drive and go. We have the electric kick-down on a switch if you turn the switch on it shifts at 6500 both shifts. Takes some testing to get them right but works great once you have it.

That is more like the set up I was contemplating for consistency in a bracket race car.

I think if you are going this route then you'd better be racing with the 4L60E transmission that e-shift was used on! Running a TH200 or 350 with e-shift should be illegal. Those transmissions never came with an electronic shift and this whole E-Shift bull**** in stock eliminator has gotten way out of hand. How is this any different from super stock?
