Dual Gate Shifter - how SHOULD it work?

I am looking for youtube videos showing how the mechanism works.

I just acquired one, and it seems to skip past 2nd and go right into 3rd

It is just a bare shifter

The slapstick gate is missing the spring, no big deal.

I am studying the mechanism to see if anything is obviously missing, no luck yet.

I sure would like to see it go exactly one gear at a time.

it appears to need to be kept further to the right during the 1-2 slap. I see a little latch that appears to be designed to stop the lever at gear 2 during the 1-2 slap, but the lever slips right past it on the left.

Insight?
I found this so far, it's just an installed one in service

Chris, you are correct that the lever needs to be pushed to the right and forward to go one gear at a time when up shifting. When it hits the second gear detent, there is a spring that pushes the lever to the left when pressure is released so the lever just needs to be pushed forward to go to third.

Applying leftward pressure on the lever while pushing it forward will miss the detent and go as far as you push it - it will go from first to reverse that way (did that once back in high school / 1980 or so - not fun at 50 MPH).

the reverse applies on downshifting - apply pressure to the left as the lever is pulled backwards in order to downshift one gear at a time. Pushing to the right as it is pulled back will allow a 3rd to 1st downshift.

Think of it as a sort of Z gate operation.

Ok Ken, gotta ask, how exactly did that poor auto respond to being slapped into reverse at 50 mph?

The rear tires let out a brief screech when they locked up but luckily no damage to anything. I realized immediately as it was happening and pulled the shifter back into D so it was a very brief event - fraction of a second in R then back into D. Scared me a LOT and I learned my lesson so in 35 years I haven't done that again.

I am surprised you got the gears to mesh and it to even go into reverse.

Automatics are coupled by fluid being directed to the clutch packs. No "gears" to mesh per say.


On a side note. Did you know one of the quality control test while testing new vehicles is to throw it into park at 30mph to see if the dentent lock works. I was watching a 30 min video on how my 03 siverado was made from bare frame to parking lot. This guy does this while doing quality control on every 100th vehicle or so. He also does it about 15 miles out on his 30 mile route. Completely freaked me out when I saw it.

I lost a first place in pro drag racing because my duel gate didn't work right. When shifting from second to third on the right hand side it popped into neutral on the left side. I had been running in drive all night. My problem was i had a faster car and knew i could cut a light but the round was to short for a cool down. I wasn't sure if it would run the number but knew heads up i could beat this guy by fendering him all the way down the track. As luck would have it it work clean till i got to third gear. When i looked at time slip i had him with a .01 light his was a .30 There was no way to recover when that happen it didn't want to go back in third on the right. I didn't try the left! If i had just left my hand on the shifter i would have won. I tried it later did the same thing and has ever since If i leave my hand on it as i shift to third and force it to stay it works fine.Oh well i normally race in drive but would fix it if i knew what was wrong.

OK, so pushing forward and NOT to the right will result in the shifter executing a 1=>3 shift when in the slapstick side?

It cannot go into R unless you were to pull left while going forward [from the RH section] because the section ends at the D or 3 position.

I could have sworn that a simple forward push is all that was necessary to go 1=>2, like Some Other Brands of shifter. I see that the #2 stop detent seems to work OK if you do push hard to the right while doing the 1=>2 forward push.

Duh. Forgot we were talking automatics. Thanks.

My dad got a 71 W-30 new and told me the story of doing the same thing. He said it was under full power in the 1-2 shift. He thought he was on the right said but was in the regular side. He said it never hurt a thing on his car either. I think it unloads the tires so bad all they do is spin maybe? I did it two times in a T bucket and never hurt anything but it is a much lighter car. The shifter was on the left side and reverse was all the way back. I was hot rodding it and was thinking wrong. at 30 MPH I hit the gas and jerked the shifter all the way back thinking that was were first was. First was all the way forward, oops.

Did the exact same thing once, about 25 years ago, in my '70 convertible with HC350/TH350.

Had a bunch of friends in the car, including one girl up front perched between the front buckets.
The car had a floor shift, but no console, and someone at some time had removed the shifter quadrant (the half-round thingie that the pawl from the shift lever engages so that you have to pull up on the finger lever to shift between gears).
I pulled out of the parking lot and turned right onto the street while flooring it, which caused girl between seats to shift her (fairly ample) derriere, which pushed the shifter from Drive to Reverse.
All of a sudden I was wondering why we were slowing down and the rear wheels were smoking and making noise.
Took me a second to figure it out, reach under her butt, and jam it back into Drive, and we proceeded on without further incident.
Never had a problem with the transmission in the year or so that followed before the engine blew up.

Didn't you have to buy her a ring?

Naah. Her boyfriend did that. He was an "open minded" guy, though, so he and I were both on "very good terms" with her .

Ahhhhh, college...

Hopefully at separate times.

Or, were you three into doing it Eiffel Tower Style?
