Hey guys, my tranny packed it in today, cant get the car in gear anymore. I thought something might be wrong when I got it. Sometimes going from 1st to second it would miss second and have to clutch again to make the shift. It was always pretty stiff going into 2nd as well as 3rd also.

I was leaving work today, driving nice from a stop light, and I shifted into 2nd gear, it missed again, so I clutched again and gave it another shot, nothing. I pulled over to find that the shifter was very sloppy, and it would not actually go into any given gear. (put it where 1st should be and I can still move it side to side) the same with reverse or any other gear. I was able to get it into a gear that I can make the car move, but it was something like 4th I'd end up burning my clutch if I tried driving it. Basically I can move the shifter in a big circle around the gearbox.

I pulled the shifter handle itself out and checked it out, it seems to be in good shape. so does the thing with a notch in it that the shifter and plastic bushing go into. so whatever the problem is, it's below that I think.

anyone have any idea weather its a shift fork or linkage?

I posted on BC rotary earlier today, and I've gotten one guy that said I should assume it's just toast. I'm hesitant to do this as I'm not convinced the tranny is useless.

Search for "clutch fork"

The issue isn't my clutch, the clutch works just fine.

I was also going to ask if a turbo 2 transmission was a direct bolt in. if that's the case, they are a bit more common. and evidently are stronger. my friend Rob is running 850hp through one at the strip, it seems to hold it.

Go back to post number two and try again.
and you are correct its not your clutch

Roll pin present or sitting in the little well? If the tranny has been abused, the selector rod end could possibly give similar symptoms - which might be worth a look....first easy step before going deeper.

Remove the transmission cover and it's 4x10mm bolts.

Then drain the gear oil from the large drain plug. Remove the 20x14mm (or are they 12mm?, whatever) from the bottom of the main transmission case. Using a hammer, strike it cleanlly from the side to break the silicone bond. Now have someone shift the transmission from above while looking from below. In 1st-4th you should clearly see one of the forks move forward or backward.

If you see damage to a fork obviously you've found the problem. If you see that one rod is moving but not the fork that's on it, that's your problem. These are not expensive in repair parts but labor is. If you don't see anything, it's probably the selector forks tucked inside the extension housing. These are pretty easy to replace. My bet is that it's these selector forks. I replaced all of mine for $100, in fact it could probably be done on the car, but I'd pull the trans just to ensure the transmission internals stay clean.

Where is this selector rod end? I need to learn the actual names of the internals.

Hey man, do you need the car running like... now? If not and you can wait until my Christmas break I can come and take a look at it.

First thing you should do is take a peek into the inspection holes on the transmission. And see if the clutch fork is broken and or cracked. Second thing to do would be to remove your shifter.

My bet is your actual case is fine but something else along the shifting or clutch end went haywire. Transmissions just don't "stop working"... How many KMS on the car?


If the transmission does need to be removed we can do that in an afternoon. I'm a pro at it now due to my build

BTW, I see some suggestions for looking at the clutch fork. Because you have mentioned that your shifter got sloppy, and won't find a gear, I think it's in the transmission itself, not part of the clutch. To confirm it's a transmission issue, try shifting with the engine off and car parked. If it does the same thing with the engine off as when you're driving, it's probably the transmission.

PS... Azriel if it is in fact pooched see how much Blackwell wants for his case in his wrecked FD.

Selector rods are accessed via removal of the extension housing, if someone has gone Vin Diesel on them, the ends exhibit a lot of wear, even in a low km (supposedly!) box.

When you say you can only access 4th gear, it suggests to me there may be a chance the roll pin holding the rough casting the gear lever sits in may have dislodged......think the hole is blind rather than through.....so you could push the box into 4th not pull into 3rd - or get into the other gear planes. Dgeesaman's suggestion to undo the cover and have someone shift, is the way to go though.

Technically i can't access any gears at all, the shifter doesn't really seem to be doing anything weather the car is running or not. it seems to be stuck in this forward gear that will actually move the car.

pop the shifter out. perhaps it broke?

Azriel_Strife

iTrader: (5)

Already did that, it's in the OP. Looks fine. check ur email, i sent one via this forum to you.

Looks like it could be my issue, but it's stuck in a high forward gear. I gotta get the selector box off the tranny and have a look.
