1968 plymouth gtx

Probably a newb question but I have a 68 Plymouth gtx 440 console 727 automatic. Everything works. But I'm missing reverse lockout torque shaft assembly I think? The reverse light switch is near the brake switch on the column near the floor. My column has no hole for a column shift. The lever on the column to activate the reverse light switch is in the engine bay. Again no reverse lockout torque shaft assembly. I can spin the column from inside to engage the switch. Also the lever in the engine compartment when engaged doesn't lock the steering wheel. Key is in the dash. I's a matching number car except for the 727 trans which by the 10000 day calendar is a 69 727 tranny. I guess I have more than one question here but if I did require the reverse torque shaft assembly for the console shift how does the lower rod from the torque shaft console shift and the rear rod from the reverse torque shaft assembly both connect to the transmission control lever? Or did buy a car that was a console shift tranny with a column shift car or a console shift car with a column shift column? I have the 68 manual and it shows the reverse lockout torque shaft assembly in the illustration. There's also no switch on console shfter.

Wow... Let me see if i can answer some of this..
1. Reveres Lock out is part of the shifter in the console
2. The Reveres Switch in the three wire switch in the transmission
3. Maybe the column was swapped at some point? Or your looking for Items that are related to the column shifter when you have a console shift system...
If you have the console installed? I would just use that Linkage and not bother with the other.

Hope that helped?
Cheers

Yes 3 wire swiitch in the tranny neutral park starting switch. I guess my question is there’s one hole on the transmission control lever. How do the rear rod from the reverse torque assembly and the lower rod from the console torque rod connect to the same transmission control lever if I were to install the reverse lockout torque shaft assembly? All the levers I see have one hole for the 727 tranny. And the rear rod and lower rod both have male ends with the use of a cotter pin. Also thanks for your reply. I haven’t been able to find any images online showing the reverse linkage set up on a console shift. Again there's no hole for a column shift lever or the PRND21 indicator on the column either. What I'm getting is whether it be column or console the reverse lockout linkage torque shaft assembly needs to be threre? I see on some diagrams with a reverse switch on the console shifter under the console. Mine doesn't have that switch either.

Ok... The Photos you have posted are self explanitory..
Maybe you could upload a photo of what your issue is so we have a better understanding.

I'm getting the feeling your taking about the upper lever (Thottle Valve Pressure Lever) thats above the shift lever that runs up to the Carburator? So I'm missing something... Sorry

Not the kick down linkage

I’m not talking about the kick down linkage… the reverse lockout torque shaft assembly….

The reverse lock out had nothing to do with the torque shaft.......
The reverse lock out is part of the shifter .. Its a plate that will not let the shifter move unless you push the button to move the shifter lever.
The torque is just a support for moving the levers to move the shifter sector shaft.

Well there are two torque shafts. One is tied to the column lever in the engine compartment that is engaged by the upper rod that is attached to a… torque shaft… (see illustration). The other torque shaft is from the console shift (see illustration)…. You missed the question anyhow but thanks for your input. I appreciate anything I can get. Have a great day!

wouldn’t know why they call it this???

****FOR COSOLE OR COLUMN…. ****

I don’t see how that is only for reverse lock out, in fact I don’t think it has anything to do with the lock out at all. It just takes the motion of the shift linkage from the shifter and applies it to the transmission, there’s no reverse lock out after the shifter at all.

First off Racer Hog appreciate the replies. Secondly. Whatever it is? Reverse lockout torque assembly whatever. I just want to know how in the heck do both linkages hook up to the transmission control lever? I get the linkages move when park or reverse are engaged etc… I need to engage the column switch on the floor at the base of the column on the interior with reverse linkage. I already specified that it doesn’t lock my column when I spin it manually to engage the switch which engages the reverse lights. it’s the torque shaft that attaches on one end to the left frame rail and the other onto the tranny. When engaged by column or console shift it moves the lever on the column in the engine bay with the upper rod to spin the column engaging the reverse light switch. Right next to where your down pipes go. Upper rods can be different lengths. Again though. The question of attaching both to the tranny control lever from the console shift to the torque assembly that activates the column and the reverse switch. Maybe I’m not explaining it correctly?…. I also can’t control how venders label their products online. Appreciate all the input!!

The quick answer is they dont !!!!

Is this the switch for the back up lights that you are trying to get to work?
https://www.napaonline.com/en/p/ECHNS6562

I do not think you can install both of those two linkage systems to work together unless you fabricate something so you can connect both rods to the transmission control lever.
I think what is really throwing me off is that you say there is a back up switch on your steering column. That's leading me to believe that the column has been swapped to something of a later model of aftermarket?

I'm thinking the only way you will be able to make the Column Shift System to work will be to drill another hole in the lever and attach the other swivel....

Reverse lights

Now we’re cooking with gas. Kind of what I thought too that the column was swapped out. The reverse lights work if I spin the column manually from inside the car on the column (again no hole in the column for shift lever or ignition key). Key is in the dash.). I can also activate the reverse lights by engaging the lever on the column in the engine bay. Reverse lights work when I do that because it hits the switch at the base of the column where the brake light switch is too. Car never had a torque assembly linkage for the reverse lights or a switch on the console when reverse is engaged. So yes the column could’ve been swapped leading me to this conundrum that I’m in. Because engaging it manually sucks while reversing. Thanks again Racer Hog!!
