There is probably a post on this topic somewhere, but I could not find it. I have a 95 civic lx 4 door with a 1.5 sohc non-vtec motor and manual transmission. When I got the car I noticed a bearing type of noise that went away when I pushed the clutch in. So I figured it was the throw out bearing and I would either have to put a clutch in it or just leave it becuase they rarely seize up. But as I drove the car, the noise either got worse or I just noticed it more. Then, I noticed that when I put it in 2nd or 1st when the car is rolling, the tranny makes a slight whiny noise. I heard that main bearings go out in these allot. And I saw in the DIY area that there is a step by step guide to replacing them becuase of that problem. But I noticed that it was for SI trannys. So I geuss my question is, is this a common problem for most honda manuals? And, should I go with the guide for the SI tranny on replacing the main bearing? Any help would be greatly appreciated.

It mostly likely be your main bearing on the tranny, it the same procedure as how I rebuilt my SI tranny you see on DIY. I have seen a TSB for trannymain bearing before but forgot which year it covers, but its’ very common that the bearing goes out on Civic manual tranny.
