Transmission Linkage pops out....

[skk0819]

Grrr. I'm starting to wish a had a later car, where some of my
issues may have been addressed by evolutions in the engineering of
the car or something....

The linkage of the shift arm to the front of the transmission has
started popping out, when i experience my "clutch chatter" problem.
Happened like three times now. This is like a ball and socket
mating....where the shift linkage goes to the transmission itself.

Whatever gear I happened to be in, that's the gear I am stuck with
until I pull up the back seat, and take it apart a bit down there.
This happened the other day for the first time in heavy traffic and
was quite nerve-racking, since I did not have the right tools to
address it. I had to limp home in second gear about three miles, it
was not fun...I suppose it could have been worse - first gear could
have been where I was stuck.....

I called Gordon's, and was told this is a problem with early cars,
since the bracket that holds the ball and socket together on early
cars is mounted to the frame of the car under the seat, and when the
transmission moves, it can pop out. Apparantly on later cars this
assembly was mounted on the transmission itself, so both pieces would
move together, and prevent this from happening.

Any suggested modifications would be appreciated (again)

Thanks!

I have a very early 62 with the first generation of everything. I'm
aware of your problem but I think that Dave (The Wave) was able to
fix/upgrade it to the later style. I haven't had any problems with
that in years. Dave really knows his way around these tranmissions.

Dear Scott, Hello, We looked at my 62 amphi at Celina with the same type of
problem and determined it had the wrong rod, the later ones were longer. I have
a 67 trans with the trans mount and all the updates and still had a problem.
What will cure mine is a new shift rod. Good luck and stay in touch, Mark in

Scott:

I have an older Amphi like yours. You might want to check the set-screw in part
11-23-46. This screw has to be backed out quite a bit to allow the ball (part
11-23-16) to fall out of the socket. Once the ball is positioned up into the
socket, you tighten the set-screw until it binds, then back it off a bit.

I just looked at the Part Manual, and, although the ball and socket parts are
shown, there's no mention of a set-screw. Maybe my socket has been modified to
deal with this known problem.

If you choose to modify your linkage to go to a transmission-mounted rod
bracket, that should eliminate stress on that ball/socket joint.

Re: Re: Transmission Linkage pops out....

Dear Scott, Hello, I also had the same problem and found the shifter was shimmed
ahead 1/2 inch . I removed one 1/4 inch shim and it was muchbetter although I
will need a longer shift rod because I have a 62 car and a 67 transmission. I
did all the updates and still had the problem. Moving it backmade the car
usable. Stay in touch, Mark Amsdill 62 blue, 62 white>

Regarding Scott's transmission linkage problem, I thought I'd add my one-cent
worth (only one cent because my car doesn't have the original bracket in this
area so I don't know all the details ).

Have you checked the transmission mounts? If they are not holding the
transmission down, it could cause the problem. You might also verify that there
aren't any washers or other spacers installed on the transmission mounts that
lift the transmission up.

I had problems with Ed's part numbers (they don't seem to match the ones in
my parts book). I assume Scott is having the 11-43-21 ball head pop out of the
11-43-26 ball seat. In addition, the 11-43-21 ball head may be coming out of
the 11-43-20 ball holder.

I found my 11-43-21 ball head to be loose in my 11-43-20 ball holder. I
could see no reason it should be loose so I fit a round shim between the two to
make for a snug press fit. If these two parts are very loose on your car Scott,
they may be contributing to your problem. Note: Since the cast iron 11-43-20
part showed significant wear, I think the forces in this socket are
significant. I thus machined a steel bushing to shim between the two parts.
I'm afraid
a softer material (brass, JB Weld, etc.) might not be strong enough to stand
up to these forces. Thus, to make this repair, you will likely need some
machine tools, like a lathe, to make this repair. If these parts are loose, you
might be better off getting new parts from Gordon's (if available).

My car is missing its original bracket that supported the aft end of the
11-43-22 shift rod. Mine is supported from the body, not the transmission.
Mine
had a poor replacement, so I made a new one of my own. I'd suggest you check
two things on your bracket. First, make sure the shift rod is not sloppy in
the bracket. The bushing in the bracket (assuming it has a bushing) may be
warn allowing the shift rod to move around. It seems to me that if warn, this
could be your problem. Second, you might see if the bracket can be moved upward
to push the 11-43-21 ball further into the 11-43-26 ball seat. You could
remove the attachment bolts for the bracket and see if the rod can be moved up
any. If the rod can be moved up some, and if everything else checks out, then
you might consider elongating the holes in the bracket so that it will hold the
rod up higher -- pushing the ball further into its seat.
