tranny stuck in first

[feellnfroggy]

the pics are a little confusing, the important one is the ring i found in the tailshaft, there is nothing else looking bad in the transmission that i can see without taking it completely apart. i'm gonna try to label the pics we'll see what happens

 

[feellnfroggy]

Here they are. I dont know what I am really looking at sooooooo, Allen?

this one is a picture of the toothed brass ring in teh tailshaft on the side of the shift fork,(theres one on each side)

everyone knows this is the tranny cover where the shifter is

a blurry pic of the cover, sorry

inside face of the tailshaft housing

clearer picture

clearer pic of same brass gear by shiftfork(5-reverse)

blurry pic of main gearset(1-2,3-4)

blurry up close of brass ringgear(sorry)

same

not really sure now.

brass teeth gear by the 1-2 shift fork, (this one is loose and only shifts one way, into 2nd)

same, clearer

5-reverse linkage, up close where i found the springsteel ring

clear up close of the brass gear where i found the steel ring

the actual ring on a piece of papertowel(prolly not hte best background)

zoomout of tail shaft

another look at the tailshaft linkage(5-reverse)


if anyone sees anything i might have mis labeled(it was all off memory) but for the most part those are the pics i took that i felt were the most informative...

Froggy that wire piece i believe is number 11 in the above break down which sits under the inside of synro hub and is the springs for the number 13 keys which do break from time to time.

Could also possibly be part of a bearing cage.

If you need this break down for your library feel free

 

[bottledgt]

nah that dont look like 11 to me at all. it should be way bigger than that. the pics are kinda foggy to tell anything, but according to the syncro hubs, it aint in first,or any gear for that matter. something must be seized in that gear possibly. hard to tell. 1st is the biggest gear at the top in the pic

I sat for hours trying to figure out if it was #6 or #11 or what. but its definitely a broken piece, its a complete ring though, its not a 'c' its an 'o' thats broken. I'll try to get better pics of the ring this afternoon.

::edit:: It really, really, looks to me like some kinda of spacer, maybe like number 8, but I dont see where it would belong that would affect first gear, I also dont see where it would belong in the tailshaft where i found it. There is a truck in jacksonville craiglist, same year make model as mine and the dude is having the exact same problem I am. Imagine that, he's jsut selling the truck for 500 bux,

I'm having a heck of a time making head or tail out of the blurry pictures, but that broken piece really doesn't look like a blocking ring (#6), and those are brass, not spring steel. One of the 5/R blocking rings appears incomplete. Is it broken? Are all the synchronizer hub keys in 5/R present? Loss of one of the springs often pops one or all out, and they can cause carnage if they get ingested between gears.

 

[AllanD]

piece #11 in the diagram is not to scale with the gears

Piece number 11 is the spring ring that applies tension to the "detent keys"
on each of the synchronizer assemblies.

there are FOUR of them in the main gearbox and two more back inside the 5-Rev synchro. for them to get OUT is all but impossible without the gearbox literally
exploding.

they are made of square wire 0.050" diameter..

that piece looks more like one of the shim rings from under the shifter pivot bushings

or remotely possibly a bearing seal from an aftermarket bearing.

Try miving the shift collars (individually) into each gear and more importantly for 1st
OUT OF gear.

BTW, if you had any plans of ever becomming a professional photographer
forget those plans right now.

Despite the quality of the pictures, I do think that I am seeing some metal particulate all over the gears.

Froggy, how much do you know about the history of this tranny?

 

[AllanD]

What I see is dust from the aluminum case corrosion

Probably from prying the tailshaft housing off after the top cover
was removed.

If there was that much metal particulate inside the trans the
mesh surfaces of the gears would look like the surface of the moon.

this is the busted ring, its definitely not brass that i can tell. i gonna take a few more pics of this.

the brass toothed gears dont appear to be broken, they are just loose on the 1-2 setup.

Again I apologize for the blurriness, yall werent supposed to focus on those, the camera fogged up soon as i went outside.

Yes there is some dirt/particulate on teh 5-reverse gears teh tailshaft and its mostly mud that fell in when removing the 'lids' the outside is just oil and mud, i knocked off the really big stuff and opened it up, but i missed a spot apparently. up close in person none of it looked like metal shavings though, once again better pics coming now that i know the camera dont like going from cold to hot, i really just wanted to get sumthing up for yall to look at, ill email them to metalmacguyver tonight and hopefully get them posted when possible, im on dialup so he's helping post them.

could be something simple.

Doubt it,
The input shaft #5 and output shaft #17 stuck together because the center bearing #15wore out, That would give you 4th gear (direct drive) without moving the shifter out of neutral. Once they stuck together, the truck rolled when the clutch let out.
Now, this is proven if you had to give the truck a lot of gas to get it rolling.
If on the other hand, it realy felt like first gear, then the shafts are not stuck together but became mis-aligned when the shafts move up or down, That put to much pressure on the sliding gears, so you can't shift.
Get some better pictures posted up if you need more help.

it has all characteristics of first gear. its not that i cant shift neccessarily i can put the shifter in other gears it just wont move. it stalls.

to answer another question, i can move the shift rings by hand, just (i dont think) not out of 1st gear.

 

[dennis461]

wont move. it stalls

Ok now I got it.
That piece of information means you are getting 1st gear and another gear at the same time.
With two gears engaged at the same time, the output shaft cannot turn, so the engine stalls.
Same principle (two gears at the same time) is used for auto trannys at the drag strip for torque converter lockup of course, that's under control with a tansmission modification.

Here are some more pictures

I believe that little ring is one of the metal washers that shim the shifter bushings.

I believe that little ring is one of the metal washers that shim the shifter bushings.

Must be an echo, I believe I said that at 12:57 this afternoon

I'd recommend pulling the little plastic cup out of the tailshaft housing and seeing what interesting bits can be found behind it...
