Need help for another car. Tranny noises.
I posted this over at 240sxforums.com but no one gave me a response other then sympathizing with me over breaking a wrench. It's for my other car, a 90 240sx. I know it's not an fbod, but c'mon, a transmission is a transmission, and I'm hoping you all will have a better answer then I got over there. I just copied and pasted it.
Ok, heres the story. My old trans leaked out all the fluid through the shifter seal and promptly blew up.
I found a trans from a wrecker from a 90 with 80k miles on it several months ago. I bought an exedy OEM clutch kit, plus nismo motor/tranny mounts and a B&M shifter.
Slowly, I've been getting everything together. Trans went in today. I put in 2.5 quarts of 80-90 oil through the shifter hole, since the fill plug was stuck (snapped a hardened wrench actually trying to get it off). I put the B&M shifter on and fired er up.
At first, everything seemed fine, but there was a little whirring from the trans. After about 10 minutes of driving, it's gotten fairly louder. It sounds like it's coming from the shifter, but that's the only direction I have since it's the closest to me. If you wiggle the shifter while its in gear with the car moving, the whirring will change and fade a bit depending on how you hold it, but it stays there. The sound is there as long as the car is moving. Whether it is in gear or with the clutch pressed in, there will be noise until the car stops. The whirring does change pitch with differant gears though and reacts with RPM.
Besides the whirring, there's no other noise. However, there's some vibration at times, but the motors running kind of funky so that could be it.
I'm using Penzoil 80-90 synthetic which many people use on that board, but Redline MT90 seems to be the most recommended. Think that would help matters?
I want to point out again that the noise changes with RPM, so I first thought it was the synchros or something (I'm not too "fluent" with transmissions, I admit it) but I noticed that even when it is in nuetral (600rpms) the noise will change tone, but will still make a noise that's coordianted with the back wheels moving until it stops. I did notice that it makes more noise in the day.
