thanks Pin and coupler were replaced not long ago

Coupler and pin were replaced not that long ago Thanks

The shift lever and the pivot may have worn some , but I have never seen one move .. That does not say it hasn't moved . If it has moved , it may be necessary to get another shift lever and replace . Thinking about this , it may be possible that the housing ( the part you can see inside the car ) has worn and allowing the shifter to have too much play .
Put your palm on the shifter knob and push straight down , shifter should move down , maybe one eighth inch .

Speaking of couplers, I just received a 96 Honda Civic steering knuckle that I'm going to install, as soon as I get over this bronchitis. I've heard good things from those that have installed it.

Got 2nd and 4th now just need to adjust for a good shift a very hard through gears still

I don't know much about the shift adjustments but is the support bracket on right or should it be turned around on the same bolts?? Or is that the only way it will go on?

You may be onto something there Jeff. I don't have a 4-speed on a lift to look at right now.
The picture actually looks like the bracket isn't sitting against the floor like it should. Looks like it is sitting on the ridge where if you flipped it 180 it would sit flat and give the shifter more throw.

[tikiwagon]

this is how it was and looks right to the manual if anyone has a pic of a 64 to confirm this would be great

[tikiwagon]

seemed to have got over this with a lot of fiddling about with tiny adjustments on the clutch arm, going for proper test drive tomorrow to see how good it is

[64powerglide]

That bracket is on backwards & that is the cause of your problem. The bracket is made offset & it's in the way the way it is & your shifting will never be right until you rotate it. Note the curve in the bracket to match the hole.

[tikiwagon]

I have just turned that bracket around and the shifting is better now, Thanks for all the help

Quick question, the pin that holds the coupler to the shaft on the trans is a cotter pin right? Someone has replaced mine with a 3/16 machine screw and nut... seems like more parts that need to be replaced...

[joelsplace]

No. It is a solid pin that uses a cotter to hold it in.

[GotHiway]

No. It is a solid pin that uses a cotter to hold it in.

Thanks!

[tikiwagon]

Check that pin as they are prone to wearing a lot

In rebuilding the entire shifter assembly (coupler, bushings, etc) on a 1966 LM 4 speed one of the last steps is to clamp the shifter shaft (rod) to the coupler shaft. It’s clear of course that the relative axial position be correct so there is no axial interference (shifter shaft to shifter tube) in the box at the forward end of the shifter shaft, but what about the rotational position of the shifter shaft relative to the coupler shaft? It would seem that the shifter shaft to coupler shaft should be in particular rotational position or there may not be sufficient rotation to get the transmission into either reverse on one side -- or 3rd and 4th on the other. That is, should the shift lever be a particular position (left, center, right?), for example, while it’s in neutral, when the shifter shaft and coupler are clamped together -- or is there a particular protocol to follow? Or does it make no difference at all?
