What's wrong wiith the pic? Need 915 trans help.

TWJ · TWJ's Garage

I have a couple more questions and a supporting picture with regards to my ongoing project to free my 915 transmission with is stuck in 5/R.

JW, I have tried several times to push in the activator pin for the backup light (with the switch removed) but it won't budge. I use a small piece of wooden dowel to protect the pin and my finger. How "firmly" should I have to push. Should I (have to) use a small hammer?

The picture is looking through the access hole created by having the pivot plate removed. My question is: Should the ball on the end of the shift finger (lower left of hole) actually be between the notches in the two shift rails that are visible? Is seems to me thats how it "shifts". I can't for the life of me move the finger up or down enough to get it to go in there, although it moves back and forth easily. Is this correct or what's going on here. Is there another problem or is this related to the "stuck" issue?

Picture is below, it didn't upload the first time for some reason.

THANKS!

that upper fork in the pic needs to be popped back so the notch aligns with the other one. if one of those shafts is in gear, the reverse fork won't move. maybe you're in two gears at once. then of course, the tip of the selector finger is aligned in the notches and the fork on the plate traps the finger when you put that back on. if the trans was apart previously, i'll bet one of the detents was not in the proper place when they assembled it. otherwise this would not have happened.

Thanks John, I think that clears up a lot of questions. I think your correct in that it is actually stuck in two gears at once. I think this also explains why the rear wheels are "locked" meaning I cannot move the car even with the clutch pushed in.

Could it be that it's stuck in 5/R and 3/4 (or 1/2) at the same time. This because a detent is in the wrong place as you suggest?

So again, I need to move the upper fork in the picture (is that 3/4 or 1/2?) to the left so it aligns with the lower one. This will "unstuck" one gear. Then I should be able to push the activation pin from the backup light switch in to get it out of 5/R. Is that correct?

I did try to move the two visible forks and they wouldn't move (easily). Again how much preasure is (should be) needed? Any tricks to this?

How do I get the finger into the notches? WIll that be easy once everything else is lined up or??? How/why did in come out of the notches in the first place?

Try using a B.A.S. (Big A$$ Screwdriver), placed where this pic indicates and use the opening for leverage.

Thanks for the input Randy. I do have one of those (B.A.S.), this will undoubtedly be one of the better uses for it!

I'll let you know how it goe's.

Still looking for help in getting the finger back into the notches once the other deed is done. Any ideas?

the shaft the finger is attached to is the main shift shaft, obviously. maybe a push/pull on the shifter will dislodge the tip from whatever it's stuck on/in/under. generally you can move it easily.

The best I can say about the shift finger is to keep fiddling with it. I kinda had the same issue when I rebuilt my tranny a little while ago. I just kept fiddling with it and was able to finesse it over to the correct position.

Looking at the pic you posted, try jiggling it up to the left, and then straight over to the right and then down into the notches. I've modified the pic I posted above to show you the path I'm talking about...have another look.

Thanks John/Randy.

Actually the finger is not stuck, I can easily move the entire shaft forward/backward, I just moved it out of the way for the pic.

I cannot seem to get it back in the notches. I think I'll get the shift rails in place first then try to finese it as you suggest, unless there's any more known tricks out there(?).
