hondapartscheap.com or like majestic honda up in rhode island will sell you all the bearings/seals you need to rebuild it for ~$100, so its like the same price to replace as it is to refresh your current transmission. the only downside would be finding f'ed up dog teeth or a burnt syncro hub or something while you're in there.

here's some pictures of a recent rebuilt i did:
ISB sitting next to it's spot in the case. tap this out with a long extension from the clutch side of the transmission.


this one has the ISB in the lower right (what's most likely making your noise)[/URL]

picture of the gear stacks pulled out of the case. you'll most likely want to disassemble these to clean the oiling holes. if your ISB does go bad, the plastic spacer that holds the ball bearings in place disintegrates and clogs the oiling holes on your main and countershaft. easiest thing to do is just have a large workbench and take pictures or number things as you pull them off. it's really no more difficult than sparkplugs once you get the transmission apart.


this is a picture of one of the gears, you'll wanna "scuff the cone" meaning take some fine sandpaper to the smooth part and take away any burn marks or hot spots. the dog teeth are the gear teeth above the actual gear itself. make sure those aren't too rounded.


this is a picture of one of the oiling holes that you should clean out of bearing remnants


a disassembled main stack. the gears on this one usually just slide up and off. no bolts or anything weird. just keep tabs so you know which order they should go back on.


disassembled countershaft. the bolt at the top of it is easy to get off with air, otherwise a vise with some wood blocks and a rag around the bottom of it and a breaker bar and you should be able to get the top bolt off. a gear puller will most likely need to be used to pull the top 2 bearings off of it.




if you have any other questions shoot me a pm. i'd be more than willing to send you more pictures or whatever. good luck dude!
