I have had it with working on this b15 transmission. I bought a non-lsd, low mileage trans. from a reputable seller on this forum and after receiving slim to no help from them, countless hours reading, and asking any local people if they had any ideas I am still stuck with the same thing.
It will NOT go into gear while off or while running. If I let the clutch out it moves forward, but if you look at or shake the gear shift it feels like it's in neutral.
The stabilizer and shifter rod have been ground down enough where I can fit my hand in between them, but you can't shift anyway so I know those aren't binding. Both the stabilizer bushings have been replaced with the E.S. polyurethane inserts. The clutch cable is brand new, along with OEM TOB and clips. I have the correct axles for it, the tranny saver bracket, and the clutch/flywheel setup was working fine when the b13 trans was pulled. The trans. was converted to a cable and didn't seem to exhibit any problems before it was installed.
I don't hear any noise coming from the trans. at all from when I had it running. I have tried playing with the clutch cable, but it did not make a difference. Forgot to mention the clutch is a ACT xtreme with 6 puck unsprung disk.
Any help is GREATLY appreciated because this car has been down a while and I need it to be up and running again. Thanks.

Have you tried to see if it will go in gear by hand by grabbing where the shifter linkage hooks up?
I would have suggested this too. You can just undo the linkage where it connects to the tranny and then grab that part with the boot and move it to engage gears by hand. That will at least let you know if everything is alright inside the gearbox.
I tried doing it by hand but to no avail. same thing happens like the shifter is connected. Does it look like the only reasonable solution is to open up the case and take a look?
Thanks for the help guys, the only help i received from miko was i installed it wrong, because he claims it was perfect. It came out of a t-boned sentra with low miles.
When you tried to shift it into gear by hand did you disconnect the linkage first?
If not give that a try and see what happens. That way you can narrow it down. As someone stated above it is most likely the linkage. I know when I helped put a b15 trans into a b13 it took a bit to get the linkage proper. Come to find out the linkage bar was bent just a hair and it threw off the entire gear throw (almost hitting the drivers seat in 2nd).
So if your linkage is bent it will definitely interfere with shifting even if your trying it by hand under the car. Disconnect it and give it another go and see what happens.

I did disconnect it from the trans. and I took a vid of it. it kinda sucks, but here it is. it sounds like it wants to go but just won't it clicks like it does want to though
As far as the linkage being bent I don't think it is because the car shifted and drove just fine before this swap. However if I can't solve the problem I will look into the B15 shifter rod and stabilizer.
Does anybody know where I could find any specs or measurements of the B15 clutch arm in case the conversion to cable was my problem I want to have the cable armed machined to look exactly like the B15 arm.
Here are some pictures of how I ground down the shifter rod and stabilizer. For reference I can fit my hand between the 2.
sounds like your shift forks if ya ask me.... you ever go to uni?
so now that's 2 votes for it being the shift forks and also to check the TOB and clutch arm. I guess my only option is to pull it again and open up the case. I'll try to pull it today and get pics up of what I am looking at.
nx2000_guy, if you haven't seen already here and on the dash in the midwest section there is a thread for the minnesota/university area. I do go down there a bit, but so do plently of other guys you've probably seen. I just didn't want to clutter up this thread with stuff not related to my transmission.
I got the trans. out of the car and I am in the process of taking pics/video of what I encountered... I am anxious to find out if what all of you said is true.
Nothing wrong here right?
Is this as far as the TOB moves forward? If I push the TOB past that sleeve it centers on it won't come back sometimes because it gets misaligned or it rotates and the clips come off the pins on the clutch arm.
And lastly I have a video of trying to shift gears. How hard should it be to get into gear?
It shouldn't be too hard to shift into the gears. I could do it with my bare hand just prior to installing my tranny.
Try opening the case and look at the shifter forks.
I'm not too sure what I am looking for and I am not too familiar with what everything should look like, but here are some quick pics I snapped. Let me know if I should check something or take pictures of something else to help diagnose the problem.
Ok, you mentioned when you let the clutch out that the car moves forward, so that means you are in gear. But which one?
I borrowed your pic for some illustration. The red arrows point to the shift forks, make sure they aren't broken within the circles marked yellow. If they are not, look for other metal shavings anywhere else within the tranny assembly.
