Default 67 Dual Gate Issue

Working on my dads 67 and have been trying to remedy this issue for 3 days.
Th400 trans and factory dual gate shifter. Car was originally a stick car.

I had a cable that came from Year One and never could get the detents/adjustments to line up.
Bought a new cable from The Parts Place listed for the Dual Gate. Cable was about 1/4 inch shorter but same issue after install.

Dimension on bracket on trans pan to shift pin set to factory dim. of 7.260.

Problem is when trans is in reverse shifter is in Neutral.
When Trans is in Neutral Shifter is in D
Trans in Second, Shifter in first.
No way to put shifter in low.

I see no adjustments on the shifter itself.
What am I missing?

The only adjustment there is on that set-up is on the lever that bolts to the transmission.

On the pin end that the cable connects onto underneath the car that part is actually a threaded stud the end of the lever has a squared off slot that gives you about 1/4" worth of adjustment fore and aft.

What is most likely your problem is the car is 52 years old. The parts they make & sell as replacement parts today are not really the exact length as to the original cable. Either the center moving part is made too short or the outer plastic sheathing is too long. I would look in the GM parts book and see what the part # for that cable was. It may not be the same part # as a cable as was for another similar GM car with a automatic transmission.

Over the years makers of these parts will combine several items into one service part. Especially since the car is over 50 years old. You have just one new cable that is all you can buy now which very well could be an amalgamation of 2 of 3 different GM cable numbers. For different GM cars (BOP) with automatic and console with floor-shift around that 67-68-69 era. I would check and see what cable they are selling, say if you had a 1969 Hurst/Olds. That car came with a turbo 400 GM transmission and a HURST dual gate shifter.


Another issue that you may have (since you say that this car is not an original Dual/Gate car); is the shifter is not installed in the proper location on the floor. You may not have the right turbo 400 dual/gate lever or the bracket is not the right bracket underneath the car to hold the end of the cable, that or the shifter is simply worn out.

I have a similar problem in that I can't get the transmission fully into Park. I rely on the parking brake to hold the car on even the smallest incline. Other than that I can get it into all gears.

The Shift Works sells parts that work very well to install that shifter. Give them a call.

Thanks, I am wondering if just the cable will work or if I need to buy all the Shift Works brackets as well.
Sent them an email so hopefully they will respond.

At this point I would just go ahead and order a brand new cable with all of the bracket/lever, clips etc. That way you know that you have a "matched set."

Thanks for all the replies. I contacted Carter at Shift Works. He replied back and I am ordering all the parts.
Shifter is out of a low mileage car (21,000) so hopefully all this works.

I had a friend who had similar issues. When restoring my 67 I found that the adjustment for getting "Park" or getting "Low" is very problematic. You either get one or the other. The difference can be literally about 1/4 to 1/8 inch of travel in the cable.

In the assembly manual PAGE 361 it shows two things I found important. First there are washers (more like spacers , see photo)) at each mounting hole on the bracket. Second, the bracket itself has adjusting screws in each side (see photo).

By adjusting the bracket up or down it changes the cable travel just a little bit and Ii am able to get both Park and Low. I also think that I have an original 67 cable, so that may be critical as well.

Do you know how tall the washers are? That may be some of the problem. This has some metal spacers and it sits a little too high.

I've had two early cars that had wooden spacers. They were, IIRC, about 1/4" thick. HTH

If that doesn't work out for you I've got an original 67 dual gate shifter with the original cable still attached.

I ran into this issue with my '67 about 9 years ago. The car wouldn't go into low gear manually. Tried a new cable. Same thing. Tried another good used oem cable.....same thing. Ended up fiddling with the adjustment of the lever down on the trans....was able to move it about 1/4" or a bit less. That fixed it for good.
