1933 transmission tower plunger
Need help as always.
I removed the transmission tower top/slider and then unscrewed the screw for plunger and there was no plunger and spring there. Now I am trying to put a new plunger and spring in the transmission tower. I must have to set the slider rods to allow these plungers and spring to fit. |

Re: 1933 transmission tower plunger
You should be able to look in the hole and see the detent notch in the shift rod, and thats where it would be easiest to get the part in, and the cover back on

Re: 1933 transmission tower plunger
All 32-38 shifter housings used the single spring/two plungers detent system, and they’re located between the two shifter rails. The plug in the side of the housing is merely to provide an access hole to remove and install the replacement parts. You have to remove the rail that is closest to the access hole in order to get to the parts. You have to compress the 3 pieces at the same time you are pushing the rail back in place.

Re: 1933 transmission tower plunger
I appreciate your help anyway. Maybe all the stuff is really in there between the two rails. I wonder how much and improvement I will have with a new spring and plungers?

Re: 1933 transmission tower plunger
The plungers are hollow and their tips will wear…..sometimes all the way through. Your comment above makes me ask, what problem are you chasing that you’re hoping this question would help you resolve?

Re: 1933 transmission tower plunger
What is the proper procedure for losing one rail to make room to insert the new plungers?
As someone who never did this before, would it be a simple matter to reposition the rail after installing the new plungers or could I get it out of alignment and cause other shifting problems. |

Re: 1933 transmission tower plunger
There may be other issues causing the pop out of 2nd gear. The detents help but won't always hold it during a deceleration event in 2nd. The thrust load changes and end play or other clearance issues can cause too much movement.

Re: 1933 transmission tower plunger
Is there something I can inspect for with the transmission in the car?

Re: 1933 transmission tower plunger
Frank: Get Mac VanPelts book on the transmission it has all of the clearances you can check some with the transmission in the car. Post some close up photos here. The transmission syncro assembly should move on the main shaft about 3/16" back and fordward. If it does not move properly the syncro outer hub will not slide over the 2nd gear teeth properly. This could cause the trans to drop out of 2nd gear and gear grinding during shifting.

There is Never any grinding. Slips out of 2nd when coasting, no power applied. Looking for the van pelt book it's been years since I saw it. Hope I don't have to buy another copy. I hate when that happens! Last edited by FrankWest; 07-07-2021 at 07:00 PM. |

Re: 1933 transmission tower plunger
in reference to the shift lever and slider rails
how easy should the slide work on the shifter? Should I decrease if it does not move almost effortlessly? |

Re: 1933 transmission tower plunger
If I understand your latest question correctly, the forks on the rods in the shift lever housing only move freely between the detents and some force is required to disengage the forks from the detents, hence the spring and cups circling back to your first question at the top of the thread. Nothing is adjustable and you cannot adjust the amount of effort it takes to overcome the spring tension on the detents in the rods that the forks slide back and forth on. Wear on the cups at the ends of the spring and/or a loss of spring resiliency would of course lessen the amount of force required to disengage the forks from the detents on the rods.
