According to one wireing diagram i have for the Push Button trans control the green and brown wire comming out of the MOTOR is CCWDE. I assume the CCW = Counter clock wise but i have no idea what the "DE" stands for.

The grey and red wire comming out of the MOTOR is labeled CWDE. Must mean Clock Wise.

What does the "DE" stand for????????

More importantly, if the motor is running CLOCK wise then which way is the selector shaft moving????? Toward "Park" or "Reverse" ?????

Packard V8--I have a unit I'm putting the finishing touches on right now--I should have it on the test board tonight, I'll file a report as soon as I have it up and running.

I too saw the "CWDE" legend on the Autolite manual and have wondered is that is an abbrevitation for "clockwise driection".

I called someone. "DE" = Drive End.

However, we need to determine direction of selector shaft when Green and Brown are energized. Does Green and Brown select toward Park or Reverse????

The idea here is that i want to hook up a couple buttons DIRECT to the motor and BYPASSING everything else. One button will run the motor toward P and the other toward Rev.

I'll have an answer for you tonight. It's a litte more complicated, the Green wire is always connected to +12V (hot) and the red and gray wires are shorted together (thru the shift relay)to ground in order to make the motor spin in one direction (stay tuned for the direction fo rotation) and the red and brown wires are connected together (to gorund), with a resistor in series (to slow the action in this directon of rotation--the system wants to turn faster in one direction than the other, this resistor is Autolite's fix)to turn in the other direction.

One word of caution--It is very easy to make the sector gear overtravel and jam against the housing, and the amount of torque required to break the secor free is in excess of what the motor can provide. Were you to make this mod I would recommend that you install rubber stop blocks inside the worm-sector gear chamber of the pushbutton actuator housing. There is about 3/8"-1/4" of free space between the sector gear and the housing at either direction of travel. a rubber block might act as a buffer and keep the gearing from locking up.

From Mr PB

"OK--here is the scoop: connecting both the Gray and red wires to ground causes clockwise rotation of the motor, which causes the sector gear to travel clockwise, toward the "park" position. Connecting the Brown and red wires to ground causes counterclockwise rotation, whcih causes the sector gear to travel counterclockwise, toward the "reverse" position.
All of the above provisos and warnings still apply.

Well I tried to seperate this into two threads but something didnt work out right...grrrr. I try to put it all back together here in a bit.

It should be, we are now talking about pushbuttons. That's how it works, you start working on T-L and end up on pushbuttons!

Ok MENTAL NOTE TO MYSELF....never use the split thread option again. Boy did that cause issues in the database.

I think the Split Thread option used to be called the "Weed Wacker" option.

My apologies everyone for starting it out under the a TL thread. I'm not sure why i did that. I think it's because i was working on the inner fender well with the PB wiring and relays and just got confused when i saw the TL title with inner fender well as part of the title.

OR maybe Alzhiemers is setting in on me or something.

Mr PB. Thank you for the answer and analysis. And yes i'll heed your warnings. The only reason i want to set up the 2-button connexion is for energency use in case i get caught out a long way from home under adverse conditions.

I've been also studying the Reversing Relay. That's what it's called on my wiring diagram. It's the relay with the 6 terminals and the ressitor on the bottom. I'll have to look at it closer but it appears to me that the reversing relay could be replaced with two starter relays with a resistor between them. Need to know what kind of resistor to get.

The reason i'me getting into all of this now is because i relocated the Reversing Relay to a more convenient point than way down on the side of the fender well. I never liked it there. Now i have it up high and nearly at presentation level. This process follows an unrelated maintenance i did to the car. REAL EZ to work on if needed. I'll post a pic in a few days.
