Is there any way to utilize a column shift auto transmission in such a way that if left in the "drive/ high gear" position the trans will shift without intervention from the driver.
at a pre determined rpm from first to second, and second to high gear.
I say this knowing that A&A, and perhaps others offer governors, but I haven't seen them at rpm levels like say 7 or 7500 rpm.
Secondly, if such a way to do this exists, could you override it and shift it manually off the column, say for water box usage or to street drive it, or otherwise use it when a predefined high rpm shift isn't desired???
I hope I am saying this clearly..... Maybe I am not.... Lol

I have looked at those in the past, just unsure if they are capable of doing what I am talking about.
My usage/ intent would be to stage a column shift automatic with the selector In drive, and have it make the two shifts " hands off" the column shifter at predetermined rpm's.
If would then have to be over rideable so you can manually sift it off the column at any rpm you want( like driving around in the pits or on the street for instance. In other words just like a bone stock car you put it in drive and it up shifts itself, but my intent would be to indeed put it in drive and leave it, but when you launch the car have it stay in first till xx rpm, then stat in second till xx rpm, and in neither case do you have to touch the shifter
Can this thing do that?

Just need to set the gov to the shift rpms you want.. I dont know what ET you have to have a race type shifter that has lock outs so it cant goo into reverse

I ran 10's shifting my old Duster off the column with a bench seat, but whacked 3 trannies knocking the selector out of position by hitting it with my leg launching the car. And once in a blue moon went first to third because the detent got sloppy.
I finally threw in the towel, ditched the bench and installed a floor shifter.
I want to do that again, but don't want to have to touch the column shifter during the launch or down track.
I don't know of any rule that you can't use a column shifter, no matter the ET, but I could be wrong. I know I never had any problems and race it a bunch a couple of years like that.

According to the NHRA rule book there is a ET that
requires a lock out type shifter(one that cant be
put into reverse without some type of lever or lifting)...
you can do what you want even with the floor type shifter
by leaving it in drive and let the governor do the
shifting... I might be doing the same thing with the
Rampage but I need to play with that

It can be done by installing a governor kit for your target rpm, problem is it probably won't shift at the same rpm on both the 1-2 and 2-3 upshift...some tweaking of the shift valve springs will take care of that.
Be aware that launching in Drive puts all of the load on the sprag so, if you're making some power, it'd be wise to install a Super-Sprag and billet front drum.
I agree. I ran my Challenger for years that way in Drive. The last trans I ran was a newer case ('74-75?) It didn't shift the same RPM's like John described. It would shift 1-2 about 200 RPM less than 2-3. My old trans was a '70 and it was the same RPM for both gears. Got a governor kit from A&A and would fine tune the shift RPM at the carb linkage by adjusting length.

here is what they say it will do
The CHEETAH E-SHIFT Controller was designed originally for the control of the Turbo Action CHEETAH E-SHIFT Valve Bodies. When the final product was completed we incorporated all the provisions to operate almost all devices (air, CO2, electric and electronic shifters, electronic valve bodies, shift lights, shock controls, low side chips, high side chips, etc.) that required a precise rpm control. The CHEETAH E-SHIFT Controller is laid out in a analog fashion so not to intimidate a non computer individual and you can change settings in the staging lanes with no additional equipment in a matter seconds. The wiring is very simple, but must be done neatly and accurately. Race car wiring in general can be very poorly done and causes many problems for all electronic manufacturers including Turbo Action!
Turbo Action CHEETAH E-SHIFT Valve Bodies are the first three speed electronic valve bodies to be produced by a high performance transmission company. These valve bodies make your transmission repeat E.t.'s within thousandths of a second. Three sets of rpm's automate the transmission completely or override as you need.
Race Mode: Set either the same or different shift points for the maximum performance.
Burn Out Mode: Set lower shift points to heat tires.
Pit Road: Set low shift points for pits and return road.
All this done automatically based on normal racer functions. No changes in your present driving except place shifter in the drive mode like a family car. The rest is done by the Turbo Action
CHEETAH E-SHIFT Controller .
The following is suggestions and tips on the use of the controller:
1. Always connect your positive and ground wires to the same exact place that your ignition system connects its positive and ground.
2. Air and electric shifters using a CHEETAH SCS Shifter change position #14, relay #5 to 2 tenths of a second or you will miss shifts or double shift.
3. Air and electric shifters must go to Position #15 and set controller to P. If you do not do this your shifter will hang in second and will not go to third.
