'84 select cable diagnosis - no 3rd or 4th gear (Page 1/2)
snyderman OCT 13, 11:35 AM
Trying to diagnose the issue. Can someone tell me if the shifter is supposed to be able to be moved to the right as it'll go left and straight but that's it....thank you

No, the shifter cannot move any further right relative to its resting Neutral position.

Thanks. After further diagnosis I believe it's the select cable. I disconnect it at both ends and all seems OK until I put the cable back on which locks things up again. Ordered one from RD.

I'm Back. I installed 2 new cables from Rodney Dickman but still can't get it into 3rd or 4th. What should I check next?

With the cables disconnected (to take the shifter out of the equation), can you move the levers on the transmission into the appropriate positions for 3rd and 4th gear?

Hi Patrick

Can you reconfirm what the correct positions are?

Thank you

Guys this is what I've got. I don't know what the positions mean so any help is appreciated.

PIC 1
When right lever is in the up position facing the front, the left lever has 3 positions.


PIC 2
When right lever is in the middle(no resistance) the left lever still has 3 positions.


PIC 3
When right lever is pushed towards the back, the left lever has 2 positions.

I don't really follow what the arrows means on your position diagram... but that's OK. The number of positions appears to be correct.

What you call the "right lever" = select lever. Selects between the different shift forks. Corresponds to left-right movement of the cabin-mounted gearstick.
What you call the "left lever" = shift lever. Shifts the selected shift fork in or out of gear. Corresponds to front-back movement of the cabin-mounted gearstick.

I have drawn the movements of the ball studs on which the shift and select cable ends snap onto. The paths they take are in green, with distinct positions shown with green circles.

You seem to have figured out the select lever.
The shift lever moves in an arc.

The three possible positions of the shift lever in this instance:
3
N
4

So far, from what you're describing, nothing looks broken.

Most of the left-right feel (the reverse wall, and the rightwards spring action towards 3-4) in the gearstick is created by springs in the shifter assembly in the cabin itself. These forces are not generated within the transmission, except for a rather weak reverse wall spring.

When I setup the select cable on a 4-speed Fiero, I use a bunjee cord to pull the gearstick against the reverse wall that originates from the shifter assembly in the cabin. Then, I shift the transmission into 1st or 2nd gear. Then, I tighten the nut on the select cable ball stud.

You may want to call a Zoom meeting for later this evening, this stuff is hard to explain.

Have you ever driven a working 4-speed Muncie Fiero? Do you know how it's supposed to work when everything is in proper working order?

Mr. Brunelle

Thanks for your post. This is my first Munci 4 speed and until two weeks ago i never had problems with it in over 12 years. I tried your trick with the bungee and still no 3rd and 4th. So based on what you have told me and what I know so far, I'm thinking it may be the shifter. Is this hole supposed to be connected to something?. I'll PM you as I have a short video of me running through the gears and not finding 3rd or 4th.

Nothing goes in that hole. I don't know what purpose it serves... perhaps setup of something at the factory?
