Gearbox Whine R34 (33 Box) Auto To Manual

[Soli93]

Hey guys!

I just recently did an auto to manual swap on my 98 NA R34 coupe. I used a gearbox from a turbo r33, with turbo r33 clutch and flywheel from a manual r34.

In every gear EXCEPT 4th, i have the whining noise (see video) which increases on acceleration and stops when the clutch is in. My mechanic friend who helped me do the conversion says the box (which i bought from him) was sitting in storage for 3 years and even after 2 weeks of driving it the oil still hasn't fully lubricated the box.

It's quite loud and ruining the driving experience for me lol, any suggestions on what I could try to solve the problem?

I'm going to repco to get some smoothshift additive later but i'm sceptical that it will make a difference.

Cheers guys!

Treated with smoothshift, made pretty much no difference

What oil did you put in the box? Have you got a good seal between the gearbox and the inside of the car? Gearboxes do whine when there is no soundproofing.

Penrite 80w90, seal is average, has been suggested I dynamat it and ignore the noise lol

input bearings can sound like that when they are on the way out. Doesn't happen in 4th because there is bugger all load on the input/mainshaft compared to other gears
