Shift linkage

[73.5blackT]

I have a question - Adjusted shift linkage using Pelican tech article on the procedure. Everything works really well except. With the shifter in 5th I can't rotate the shift rod as it says "must be evident". When I look at the shifter and the shift coupler with the "new bushings" I can't see how there can be any rotational play.
Any advice is welcome.
Thanks

Did you loosen the allen-head set screw on the coupler?

No, diden't loosen the allen-head screw - the procedure did not say anything about doing that. What should I do, what is the procedure??

Thanks

I do not have my shift coupler handy, but I will try to explain. Because 4th gear goes "out in the tulip patch" often, I need to regularly adjust my shift linkage. I have a type 911 transaxle, BTW.

When I took the cover off, the first thing I noticed was that there was a small allen head set screw that attached the coupler to the transaxle's gear selector rod. There was some play in the fore/aft direction mainly (and a little rotational wiggle). When I tried to go to 4th, moving the shifter lever forward, the shift coupler and selector rod moved rearward.

The set screw was loose so the shift coupler moved back towards the transaxle without the selector rod moving until it hit the end of the flat area on the rod where the set screw sits.

I tightened the set screw, locking the shift coupler to the selector rod, with the shifter lever in the REARWARD, odd gear plane. When I did this, 4th was a clear push to the right and up from 3rd. It felt like a rifle bolt action.

You should be able to tell if this is your situation once you locate the screw. It will become clear where to have the shifter lever when you reposition and tighten the coupler.

Look at the rear of the shift coupler, where it joins the gear selector rod.

If you need any more info or a picture, please ask. I hope this helps.

BTW, if I do not understand your problem correctly, please let me know. There are several rods and linkages to confuse without specific terminology.

If you want to rotate the front rod from the shift coupler that goes to the shifter lever, the shifter must be in neutral, of course. To rotate the rear selector rod to the transaxle requires more force.

Not trying to insult your intelligence, just trying to get on the same page.

If the transmission goes into every gear without issue then you should be good. Do you have a gated shifter? or short shift?

I think the tech article is referring to shift lever play vs shift rod.

My shift rod doesn't rotate when in 5th either. Im referring to the 915 Transaxle.

Thanks all the responses. It's a 73.5 915 with a stock shifter. It shifts very well in all gears now and I'll just let the rotational issue go but I still wonder what they are talking about in the Pelican Tech Article??
Thanks again

You don't need to loosen the set screw of the coupler to do the adjustment. Forward, rear, and rotational adjustments all controlled by the clamp. Search for J. Walker's instruction on transmission linkage adjustment. HTH.

In fact, the set screw fits into a drilled recess - it does not move around for the adjustments.

Really???!!!

I better check my linkage because it sure seemed loose, not like it was in a threaded recess. It felt like it was on a flat spot of the rod.

Could this be a 901/911 quirk?

[C4 Pazzo]

No. The 901/911 shift rods also have the recess for the set-screw to seat into. Loosen the set-screw and slide the coupler and take a look. That'll help you locate it when you put the coupler back on the shift rod.

[Flieger]

What do you mean by recess? Is it what I would call a "flat"- an area on the shift rod that is machined down so that the set screw can grab onto it?

I think if we all had a shifter set up to point to, we could communicate our thoughts much more clearly.

[RWebb]

No - it is like a dimple, not a flat. The sharp tip of the allen 'cone" screw fits into that dimple. The cone screw is in the metal cup that the shifter bushing fits down into.

IIRC, it faces to the L (driver's side) when the rod is correctly installed.

I am not sure re the 915 shift rods. I have one in the garage if you want me to check it.

[C4 Pazzo]

Now I'm not sure if we're talking about a 915, but for a 901/911, it's a hole that the tip of the set-screw mates up to -- not just a flat area.

The pic below shows the shift rod towards the left, and the coupler towards the right (separated from the rod), with the set-screw held above them.

[Flieger]

Thanks for the picture. Now I think I see what is going on; the recess in the selector rod has probably become elongated.

The car was worked on by many people while becoming a track car. The shift coupler had to be replaced because it sat and the bushings cracked and fell out. The parts must have been given too much force by someone years ago.

I will examine it later today, after my drive before it rains.
