I wanna say that sounds like a broken shifter fork.

Z32 parts work.

the Z32 transmission internals is exactly the same as the skyline transmission...only siddefernce is the length of the main shaft...all the gears and moving parts are teh same..so yes they will interchange...if you need a fork i do have a spare one if you need it..just let me know...ill let it go for a reasonable price. you can email me at [email protected]

Ok cool thanks. I do have another question. I've read before the z32 gearbox will mount up to the rb bellhousing but the only thing I see wrong is the shifter is a Lil different n it's shorter than the rb gearbox so I would have to make another driveshaft. R am I missing something there

i am running a Z32 transmission behind my RB, go onto photobucket and search for this name (S14MARKSR)...there is plenty of pictures in there to give a good idea as to what is required to make that work. I am also goin to be selling an RB25 transmission in superb working order if you are interested in that as well. its a newer style RB25 NEO transmission with only 45,000 miles on it ...the only thing you would have to do to it would be to swap the front bellhousing ...the reason you need to do this is the NEO is a pull style clutch and not a push and the slavce cylinder is mounted differently...you will need to modify the driveshaft "AGAIN".., you will also have to change the entire shifter design, as well as cut a new hole in the floor for the new shifter to fnd its way into the car properly.
