Trannsmission blues, let me tell ya....

First off Ill start by saying One night after a hard beat on the car, while driving home is Stopped going into 2nd (3rd was blew out) 4rth and reverse, only gears I had were 1rth and 5th....

I was led to belive that mabey from 3rg gear blowing out, its teeth probably F*ed the other gears up, I pulled the trans, puklled it apart and found both 3rd gears were totally stripped ( As given, I knew it was blow) and only 1 single tooth mission off 5th gear, everything else physically looked fine.

So, I got a whole new gear set with new shafts, all new input output and differential bearings put in. The shafts That I got was already fully loaded, all the gears were on there and bearings pressed on so all I had to do was put the shafts in and put the case back together.
So my first time at doing it, I spent hours of making sure everything was right, clean. Everything wen back in the way it should have.
Put the trans in and it doesnt want to shift worth shit... then I start the car then it wont shift into ANY GEARS!

So, I assumed it could have lied in the shift linkage assembly, so i swapped then out with another set I had and still no shfit! ( yes the bushings are in the stablizer bar, ES, and the nilon sleave bushings are in the shift linkage and the shifter.

So I assume I meesed something up and thats what I get for trying to do something myself.
So I took the trans back to the guy who helped me builtit the first time I killed 3rd gear. Got it back, put it in and at first it wanted to shift into some gears but then it wouldnt. I turn the wheels some ( I have not even attemted to start the car ) And it was REALLY hard to turn the wheels, then get in the car and now it wont shift into ANY GEARS again.....

Im thinking back to when I took the trans apart, the shift forks physically looked fine and not bent or anything, the bearings were" shimmed" or so I was told they were....
So to you trannie Guru's what do you think the problem is? It has to be the shift fork,no?

Im wondering if the ring on the shaft that the fork sits into may be bent? But this cant be, It was on a perfectly fine working loaded shaft (or so I was told)

Im going to attempt to rip it out again, but at this point, im cluseless as to what it could be, Like I said, every single bearingin the tranmission is brand spankin new.

Sure the shift linkage is connected?

When mine broke, I sheared the bolt just after I put it back in and it wouldnt shift worth a shit, and then not at all. I was about to go nuts cause it was a new trans.

And another thing, when I broke the trans, it wouldnt go into anything but 4th... i took the trans apart and after 6 hours I finally found that a piece, no bigger then a nickel had broke off the shift fork.

Could be the pilot bearing gave up not allowing the imput shaft to be independent of the crankshaft. Mine just recently did this. I was lucky enough to catch it before I was in your situation though.

I've never seen stripped gears in a trans.
I've seen hundreds of puked transmissions.

ha , yea Ive done it 3 times already 350 WHP in a crociery getter on a stock trans will do it.

Back on topic, your saying the shift linkage INSIDE the trans? Mabey that bar that runs from outside the trans to the shift forks?

Make sure the synchronizers move freely . Where they taken apart ? Don't move the shift ring to far or the clips will pop up . Are the brass rings wore down to far , teeth missing ?

If the synchronizers look good and move free , check the shift plunger and ball , make sure the ball is in the right position .

Psycho - Those gears appear to be stripped.

Funny what 300whp does to a tranny that is designed for 100... LoL

Yes 5th gear synchro was messed with, took me and hour to get it back on with the keyways. I Do keep in mind that it can be the shift interlock block.

did you put it back together right? you can put the 5th gear syncro on upside down and it will cause issues, as for the syncro ring on the main shaft beign bent, you will break a sift fork before bending that.. and if you dont put the detents in the right way with the retainer rings they will work once and then bind up.. I found this out the hard way ..

"detents" What is this? Im thinking apart of the synchro?

The detents/clips/dogs are the Hub Inserts ,they fit on the Sleeve , then the sleeve goes inside the Hub , the Blocking Springs hold the Inserts in place . If the inserts aren't positioned correctly with the springs they'll pop up and block the sleeve from moving inside the hub .

At his point, a trans set up is needed.
We don't know what preloads and clearances there are right now.
And with your big power output, you have to be certain.
Time consuming and a pain in the derrier, but once you have it out, more time is needed.
