You can get any FWD SR20 transmission, so Sentra/200SX SE-R and NX2000 transmissions will work too. Being cable operated will make for a drop-in swap. Try going to a junkyard and seeing if they have any 5-speed G20s, NX2000s, or Sentra/200SX SE-Rs; if that doesn't work, JGY has JDM transmissions.
yeah i got a sentra lsd tranny, car runs quick. but if u have a lil more $$ to spend i would get a P11 lsd tranny. they are stronger, you just have to change a few things so they can work on a P10 car.
Also i had got a engine from soko a think it was a 99 or 00 engine don't know if it'll make a difference in choosing a tranny. Up to what year tranny can it fit on there could it be like the engine a 99 tranny?
