transmission question

[NaH]

Ok so we got my transmission almost bolted back up, and we noticed... there was nothing wrong with the older clutch, flywheel, or pressure plate, or throw out bearing, so..... before we took it apart it would grind like crazy in the gears and when i would hold the clutch in and rev the car, u could hear a loud roaring sound like something was spinning .. could this be my actual gears be going bad? and my transmission needing to be rebuilt? if so how much does that cost if anybody knows? and would like a s13 transmission fit my 95 s14?.. cuz if it will then i may just buy a new transmission, all these places in tennessee that do transmissions want an arm and a leg for it.

Well.. I will be honest, it is really hard to diag a noise over the internet.. but I can tell you that a trans from any KA 240 will bolt up to yours, single cam and dual cam. Hope that helps Its just the drive shafts that changed between the years..
