Ongoing Hurst Dual Gate questions
Well, I've messed with my Dual Gate shifter some and it's still not adjusted to where I want it to be. But, I have spent most of my time working on stripping and priming the body and done a little bodywork to prepare to paint the 442.
My question, how did they adjust these shifters and the linkage on the line? I'm sure they might have only had a couple minutes to adjust each car's shifters and transmissions. Most comments on here say to just keep playing with it and you'll get it. I'm thinking there had to be a factory procedure to adjust the Hurst Dual Gate shifter and get it right the first time. Is there any documentation of that factory process. Or, are there any workers still around from that time that could relay the procedure that was used?
Right now. my car sitting in my garage, set in Park, will roll backwards without the parking brake set.

There is nothing magic about the dual gate (or Lightning Rods, or any AT shifter). The trans still has only one gear selector shaft that operates through a fixed range of motion. That means that no matter what shifter you have, the transmission end of the cable still needs to move by exactly the same amount to select gears. Aftermarket parts can have the wrong lever arm on the brackets, but factory parts will be correct. I assume the bracket on the trans selector shaft is OEM, along with the bracket that holds the cable to the trans pan bolts?

Joe:
I'd imagine the linkage and other tranny parts are original equipment sine my brother bought it from the original owner in Houston, Texas back in the mid 80's and it only has 47,700 approx. original miles on it. The only exception is the shift cable that I messed up and replaced with a NOS correct (in the plastic GM wrapper) cable. It has the original motor and I believe Turbo 400 (I need to see if I can find the number on it when it's up on the lift). I'll look at the adjustment soon using the page ou sent me.
Thanks, OLE442

Adjusting procedure here for dual gates. This is actually 68-69 H/O dual gates, but procedure should still work. Only difference is Hurst says put trans lever in neutral by hand with sliding nut loose. Put shifter in neutral, then tighten down trans lever adjustment bolt. 6 of one, half dozen of the other IMO since they all have to go into every gear. Hurst pretty much wanted you to do the neutral adjustment on all their automatic shifters IIRC. Does it matter? Who knows? After you're in park, make sure that the backdrive rod puts the column in position to lock the wheel and take the key out.

My car has all original Dual Gate parts and adjusting it to get Park on one end of the range and 1st on the other end still takes many cycles of adjusting, trying, and readjusting to get it right. And any slop in the backdrive linkage adds to the effort.

I think I was able to get mine adjusted by setting the neutral on both the shifter and tranny.
I think because it's centered at that point, the travel of the shifter will determine the endpoints correctly.

Hell of a lot more straightforward than the following hour long saga of realizing a floor shift 72 still uses a column shift neutral safety switch. Previous aftermarket shifter had a neutral safety on it. Now I have order all new linkages after canning all the drive linkages 20 years ago
