Hi guys,

I'm new here, and I need your help. I got a 1997 Honda EX 5 sp manual, and the tranny was making noises while in gear. The noise was dependent on the RPM, the higher the louder generally. The sound goes away when I engage the clutch. I read a bit about it and came to the conclusion that it was probably the input shaft bearing. I went to a dealer and bought one, but it didn't fit. The dimensions were 52x26x15, but the ISB that came out was a 58x26x15 (hence, I think this tranny is pry from a newer gen civic, like a '03). The bearing that came out was making a ton of noises when I spun it, so it seemed to me like it needed to be changed regardless.

Now that I have the unknown tranny apart, I don't know what I'm doing. I took some pics of things I have questions on. Can you guys please take a look at them and respond? Also, any advice on how to put it back together is greatly appreciated.



The first two pictures here are of a bearing that I can move up and down a few mm's. Is this a bad thing?






The next six pictures are of things that the gear selector holds on. Please forgive my ignorance and lack of proper terminology. The reason I'm showing them is because I don't know if I should have all three of them in a certain position (all three up, or down, or what?) and what they do. Are they involved in gear selection? How do I put the tranny in neutral?



















The pic is of part of the gear selector, is there a trick as to how to position it when I put the selector mech back in?




These last two pictures are of various areas, just in case someone spots something that looks like it needs attention.







Thank you all for your help, it is greatly appreciated.

Read my article on manual transmission bearings, you will learn a lot. Search for it.

A gear noise that both persists with RPM and load changes points to the differential. The two end bearings on the countershaft, including the snap ring bearing, have provision to load axially, and unless they show signs of brinelling are not the source of your problem.

The mainshaft is prone to walking due to a worn out ISB and preload washer and shim. This usually causes shifting problems. The type a quality of the oil you use can also affect gear noise, especially if it is low.

The pictures you provided show no evidence of gear meshing problems, the final drive is not photographed, nor is the condition of those bearings.

How sure of you to say that this tranny came from an 03?

O3 civic use cables to shift not rods like 92-00 civic
