My 91 crx si sounds like a bus(roaring noise like bad bearing or something) in 1st and 2nd gear. You can hear it slightly in 3rd sometimes. Could it be the shifter bushing? Or, is it a bearing in the tranny? I just recently swapped trannys after i changed my 1-2 shift fork, and i remember the other tranny had a similar noise. This is what makes me think the noise may be coming from the shifter bushing and not the tranny, but i'm just thinking. I'm hoping it's the bushing.
