Hey All,
Lorrie Van Haul is a 1967 Dodge P200 Postal Van with a 225 Slant Six Engine and an A727 TorqueFlight Transmission.

There is a linkage between the Throttle Bell Crank just below the Carburetor, and the Transmission.

This arrangement is what kicks the Transmission from 3rd gear down into 2nd Gear when the Throttle is floor-boarded.

THAT link has an odd shaped "loop" on the end of it.

There is a pin that is perpendicular to the Throttle Linkage.

Onto this pin fits a big, sheet metal "washer", followed by an odd shaped "loop" on the end of the link going to the Transmission, followed by another big, sheet metal "washer", which is held in place by a Cotter Pin.

What are all those parts called? I know that they are not called "odd shaped loop" or "big sheet metal washer".

Want to know the proper names of the parts in this mechanism so that THAT arrangement can be discussed coherently.

What needs to be known is: How does that mechanism work?

It seems to be terribly tenuous not only in design, but also in construction and function.

Hey Daniel and Doc,
After seeing the drawings that Doc posted, got to looking in the Chilton's manual, and it had the same drawings, except that there was an insert which I had overlooked. Here is that insert:



The connection to the "Carburetor Pin" is not the way it is on Lorrie, but from there back, the mechanism is pretty much the same.

Am seeing the problem with Lorrie is that the "Spring" is missing. and THAT is what made the arrangement so tenuous.

There is even an explanation on how to adjust the "Kick Down" function.

Also, in the drawing, the "Adjustable Rod End" is not exactly drawn the way the actual part looks.

What is needed is to obtain the Spring, and everything will be alright.

Thanks for the responses.

JC

Hey All,
While awaiting delivery of the PROPER Brass Nuts with which to install Lorrie's Manifolds (which should occur mid-afternoon on Monday), got to looking at the Throttle Linkage that is supposed to kick Lorrie's A727 Torque Flight Transmission from 3rd gear into 2nd Gear when the Throttle is quickly floor-boarded.

In the drawing in the previous post, it shows a Spring between the "Carburetor Pin" and a hole in the "Transmission Throttle Rod".

That "Spring" would seem to hold the Transmission Throttle Rod forward toward the "Carburetor Pin" with the "Carburetor Pin" resting against the rear most end of the oval hole in the "Adjustable Rod End".

BUT, there is an anomaly here: Not only is there no Spring on Lorrie's Linkage, there isn't even a HOLE in the "Transmission Throttle Rod" into which it would be anchored as is shown in the drawing.

Anyway, cannot figure out HOW the Throttle Linkage to kick the Transmission from 3rd Gear to 2nd Gear when the Acceleration Pedal is floor-boarded is supposed to work.

I am missing something, but don't know what.

JC

Yeah: a factory service manual. The Chilton book will not get the job done, you need the real, actual factory book for your year and model.

Hey Daniel,
Alright.

Hey All,
The Transmission Throttle Lever on the Starboard side of Lorrie's A727 Torqueflite Transmission has a travel from "swept-forward" about 45 degrees to "swept-back" about 45 degrees.

Where should it be when the vehicle is at rest with the Engine shut off, the Gear Shift in Park or Neutral, and the Acceleration Pedal not depressed?

Thanks in advance for any responses.

JC

Adjust the linkage so that when throttle is full on, that arm is in the full aft position.
You like that sailor talk from an old artillery sgt.

Hey Richard,
That is how Lorrie's Transmission Throttle Linkage is presently adjusted. Have to say that the whole Linkage setup is terribly loose and sloppy/floppy.
Well, there IS a reason for using the term "starboard". You see, Lorrie is a right hand drive Postal Van, and if I used the terms "driver's side" and "passenger side" the impression that would be given would be 180 degrees off for everyone. And even at that I used the wrong term! It should have been "port" side of the A727 Torqueflite Transmission. Sorry about that.

When Lorrie is just sitting, her Transmission Throttle Lever is at a 90 degree angle from the center line of the Transmission. Considering the amount of travel from fully swept forward to fully swept back, the Transmission Throttle Lever is half way open when Lorrie is at rest. From what I can make out, there is not a time when the Transmission Throttle Lever is EVER in the swept forward position. Was not sure that THAT should be the case.

Anyway, thanks for the response.

JC

Hey All,
Well, Lorrie's mighty 225 Slant Six Engine is finally up and running. Ran it for about an hour yesterday. Had the A727 Torqueflite Transmission working. Did the Neutral, to Reverse, to Neutral, to Drive, to Neutral routine and checked the ATF level. Put the proper amount of ATF in it, and after about half an hour of running, it began shifting from 2nd gear into 3rd gear.

Adjusted the Idle RPMs to where the Engine won't die when sitting still in Drive. BUT, at that RPM, when going from Park to Reverse, or from Neutral to Drive, it seems to "slam" into gear.

This feels like when one revs up the Engine and then drops the Transmission into Drive.

There is a Lever on the A727 called the "Transmission Throttle Lever". When the Acceleration Pedal is to the floorboard, that Lever is pushed all the way back.

When the Acceleration Pedal is in the released position, that Lever is at a 90 degree angle to the center line of the Transmission.

That Lever CAN be pulled forward manually, but it has no mechanism in the Throttle Linkage to make it attain that position.

From what I can gather, the Transmission Throttle Lever controls the ATF Pressure in the Transmission.

When the Lever is pushed back all the way, that's when the pressure is the highest.

Wouldn't it stand to reason that if all the way back is the highest pressure, then all the way forward would be the position where the pressure is the lowest?

Lorrie's Transmission Throttle Lever's normal idling position is half way between all the way forward and all the way back.

Am thinking that maybe if a spring were put on the Lever and attached to the Transmission Throttle Rod that would make it to where it would pull the Transmission Throttle Lever all the way forward, and then when the Acceleration Pedal was pushed down it would push the Transmission Throttle Lever back further and further till when the Acceleration Pedal were on the Floorboard, that the Transmission Throttle Lever would be all the way back.

What I'm thinking is that with the Transmission Throttle Lever pulled all the way forward with the Transmission in Drive and the Acceleration Pedal at idle, that maybe the Transmission wouldn't go into Drive so harshly.

Whaddaya think?

JC

Hey All,
Am going to be checking Lorrie Van Haul's 8.75" 3.91:1, SureGrip Differential's Lubricant Level today.

Looked in the Dodge Manual and it says that it takes MOPAR SureGrip Lubricant.

Have never, since Lorrie came to live with me, known that Lorrie's Differential was a SureGrip. Have just been using NAPA SAE 80w-85w-90 Premium Gear Lubricant.

But NOW that I know it's a SureGrip, the proper lubricant SHOULD be used. The problem is that there isn't a MOPAR Dealership in the area.

Is there anything available at NAPA, AutoZone, or O'Reilly's that would be proper to use?

Any information would be GREATLY appreciated.

JC

That would make sense if there is slop in the throttle/kickdown linkage. Or the lever on the transmission isn't the correct one, 904's had a lot of control arms.

I use Lucas 80-90, and right on the bottle it does state: "Standards: EXCEEDS ALL GL CLASSIFICATIONS. EXCEEDS SERVICE LEVEL API MT-1, API GL5, MIL-PRF-2105E, MACK GO-J, PG-2 LIMITED SLIP" (that was a copy and paste from details on oil from Autozone)

I am NOT up to what the spec was for your van, But usually you can find whether or not it can be used in Limited Slip/posi-trac/trac-loc/sur-grip diffs right on the bottle... There are also additives that are avail in the same area as the Gear Lubes are displayed.

Hey Richard,
The Transmission Throttle Rod's Adjustable End ("throttle/kickdown linkage") is so loosy goosy that it rattles, BUT, have been told that THAT's the way it's supposed to be.

There is one of my posts in this thread that shows a drawing of the Transmission Throttle Linkage in an exploded view. It is kind of a Mickey Mouse set-up.
Lorrie's Transmission has not had any changes made to it since she came to live with me in 1975. Also, it is not a 904. It's an A727 Torqueflte.

Was just out with Lorrie. Had her mighty 225 Slant Six running for about 40 minutes. Adjusted the RPMs with a Dwell Meter/Tachometer Instrument. Turned the Idle Adjustment Screw out to where the Engine is idling at 450 RPMs in Drive with the Rear Wheels not spinning.

When the Shift Lever is put into Neutral or Park, the RPMs rise to 750 RPM.

Am still detecting a slight miss at startup that gets to be less and less as the Engine warms up, but it hasn't ever gone away completely.

Also, the Transmission slamming into gear is less now that the idle has been turned down.

Haven't yet got the knack of how Lorrie LIKES to be started. She seems to flood really easy. BUT, when she's warmed up, just a touch of the Start Switch and she fires right up. Hopefully, she'll teach me how to awaken here so that she will fire up without all the tenuousness with which she presently starts.

Anyway, thanks for the input.

Hope YOU are well.

JC
