Default Lost Neutral

so how does one best find the Neutral gear ?
mine was there earlier in the day... it's gone now.
where did my Neutral gear go ?

I can shift into the other gears... just not Neutral.

any suggestions before I pull off the shift tower ?

the clutch works fine.

Bent or broke shift forks maybe? I thing the tower has to come off.

Neutral is NOT a GEAR, so there's NOTHING to go ANYWHERE or to get LOST???
I think we need a better explanation of what happened?????

Yep,more info needed.Does it go into all the gears,and out again,with a positive click with every move of the lever?When you start the car,does it try to drive off no matter where the lever is?Start with those things,then we can ask you some more questions.

If you don't have neutral, I would not start the car or attempt to drive it without pulling the transmission tower and fixing the problem. If it is a shift fork issue, you could lock up the transmission or break the gear case and or gears.

If you take off the shift tower, also check that the ball at the end of the shift lever is round and is not squared off. However, if you are shifting into all the gears, it is probably not that but is worth checking if the tower is off. Also, when you can't find neutral does it stay in gear? If so, is it always the same gear or different gears depending on where it was before you tried to shift to neutral?

Additional info:

So I drove the the 30 Truck, and ran and was shifting fine.
I went up the street, stopped and turned around shut it off to check it out as I had just re-built the entire brake system.

I hopped back in the truck, the wiggle the gear shift thought I was in Netrual, and tried to turn over the engine to restart the truck, the truck moved,
I put the clutch in and the engine started, so I took off down the road back home ( 1000 feet ) I went to turn into the driveway ... put it what I thought was neutral.... and the truck moved... as I let the clutch out.
I wiggled the gear shift to find Neutral.. no Neutral there.

I Just thought some had had this happen and would have some easy fix.

like when the starter bendix gets stuck and the engine won't turn over.

Seems that if I shifted the lever into this problem... I could shift out of it.

Pull the shift tower to inspect. Do not start or run the engine with the tower off. Oil will go everywhere.

The answer will be in there. Remember, when diagnosing it, stuff inside moves the OPPOSITE of the way the shifter moves.

A few years ago there were some REPRO shift levers that were made in two pieces and screwed and threaded together.

Some of them came apart into two halves or loosened up so lever "flopped around" and lower 1/2 of lever did not move forks very far.

I do not remember whether they came unscrewed or if female end split and it came apart.

I must be missing something here. If you know how a transmission works, as it goes from one gear to the next, not having neutral, between the gears, is impossible. When going, let's say, from first to second, as first gear disengages, the trans is in neutral before second engages. Same with second to high or reverse to first. As stated, neutral isn't a gear, it is lack of gear engagement

Hi CarlLaFong,
So yes, you can have a transmission that does not have a neutral with the gear shift lever.
and it's not impossible, maybe just impossible to drive and shift.
...many planetary based transmissions don't have a neutral.

I have rebuilt several Model A transmissions, I know their setup well.
You can slip it into 2 gear ranges at the same time and lock it too .... not fun.

I would guess that the shift fork is bent or such, I'll post some pictures when I Pull of the tower.

I think Carl was referring to the Model A trans NOT " ...many planetary based transmissions".

And I agree with him. If it is NOT in gear it is in neutral. If you shift out of 1st, but have not engaged 2nd, where are you?

MMM don't know if this applies but many years ago I had built a 30 ccpu with a chevy v-8 and a flat head rear end converted to open drive shaft. On the freeway it kick out of high gear ( third). I put it back in third and it popped back to neutral. I looked in the side view mirror and to my horror the cheater slick was coming off. I was lucky to gently get to the shoulder. I jacked up the car and the wheel feel off in my hands. In my case I had sheared the outboard end of the axle.

Perhaps 20-25 years ago I had something similar happen. The repo Model A clutches made may be 35+ years ago had some springs spaced around the center. When they were made there were tabs that were suppose to hold the springs in place, however the tabs were not quite big enough and a spring could pop out under certain circumstances and wedge between the clutch and pressure plate there by not allowing the clutch to disengage and basically keeping the transmission in gear at all times. As I recall when I replaced that clutch, the new clutch had tabs that covered more of the spring to hold it in place. Back then we did not have the internet to share our problems but as I recall I had heard of others that had the same problem.

I had been wondering about this possibility too but when the OP said that he can start the engine when the clutch is pressed and the car doesn't move like it did when the clutch was out, I dismissed it. I saw a guy a few years ago lose his clutch when a piece of the lining broke away from the plate and wedged between the clutch plate and the flywheel. The result would have been very similar to having one of those springs come out of place.
I find it difficult to imagine how neutral could disappear but I wonder how much experience Mr Tomball has with these gearboxes. Maybe he has reverse, just can't find it?!?!?!
I'm looking forward to learning what is going on here.
