transmission

Hello all, I am a longtime lurker on these threads and a first-time poster as a new 1991 NSX owner. I’ve wanted an NSX as my dream car ever since high school and have recently been able to finally get my hands on one for a good price, albeit an automatic rather than a manual. I was able to find...

NA1 1993 MT Trans, 135k Miles. OEM clutch has 30K on it and works great. I have changed the fluid 2 times with Honda MTF since 90K miles. 2nd gear grinds all the time from 1-2 during high rpm or quickly. Very annoying. I believe it is the synchronizes or the actual gear itself from reading the...

I know everyone's been waiting with bated breath for this once-in-a-lifetime opportunity to own my used low-mileage stock automatic transmission removed from my 1990 JDM NSX for a transmission swap to manual. The transmission had no issues when removed, all shifts were smooth, confident...

It's been a while since I've been on the forums but necessity has brought me back in... I had noticed over the past few years that my car would periodically slipping or jumping out of gear. Wasn't even sure what gear since it was infrequent. I thought maybe I was not pushing in gear possibly...

Presenting several of my leftover parts from my recent 5-speed transmission rebuild and manual swap. Used unless otherwise noted. Most of these will be thrown out or used as wall ornaments if they don't sell. Willing to ship from ATL, buyer pays for their desired shipping method, don't worry...

Me again... I'm putting my old reverse gear back onto my new NSX-R 4.23 countershaft and notice both the gear and shaft have oil holes at the same "height". Of course, the FSM doesn't show anything about these holes and I didn't take note of how the gear came off when I was pressing it. How am...

Greetings everyone, I'm in the middle of my 5-speed transmission rebuild. It already has the JDM shorter gears for 2-4 installed, and I'm putting in the NSX-R 4.23:1 countershaft, ring gear, and oil pump drive gear as well. I've completely disassembled both main & countershafts for inspection...

Hey everyone, I'm Tyler and I’m pretty new to forums in general but wanted somewhere to document my journey with this car, give credit to some long-time members that have already helped me through old forum posts, blogs, FB posts, etc., and hopefully help some current and future owners if they...

Hi Prime, Selling my 5 speed transmission from my 92 NSX. WAs in perfect working order before being pulled. The reason I am selling is that I swapped in a 6 speed gearbox. Transmission has 105k miles on it with about 10k track miles zero issues; no pops, grinds. Perfect condition specimen...

See actual post below :wink:

Hey NSX Prime. New owner, this is a great place for info. Thanks for all of it. I have an NSX with an aftermarket clutch that I just picked up. Generally ok to drive, but if I drive it hard, the shift from first to second is so violent it sounds like the engine is trying to bash through the...

Hello Prime People! I am getting my clutch kit replaced, and it was recommended by my uncle/mechanic to get a kevlar twin disc clutch kit. I have done some browsing on the internet, but I can't seem to find what I am looking for. If anyone has a new kevlar twin disc clutch kit for a 1992...

We are currently working with a company to have a custom gear set build for the 5 speed transmission. We are very early into this project but designs and gear ratios are in prototype stages currently. The shift pattern will remain the same but will have a straight cut lift to shift gear set. Cad...

Just dropped my NSX off at Honolulu Acura to get my NSX looked at. It's a '92 in the snap ring range, but had the issue fixed a few years back and has an SOS clutch. I was driving and into first from a light I just felt grinding and I was unable to shift without really jamming it into gear. I...
