Tools
10mm socket (1/4 drive deep well works best)
12mm socket
10mm allen key
14mm allen key (or ghetto bolt)
snap ring pliers
Press (or take it to a shop)


First start off by taking a 10mm allen key and removing the lock for the shifter, then remove the 4 10mm bolts on the shifter. You may need to giggle it a little to get it out but it should pull out.

Next Remove the 14mm plug from the end of the trans, i didnt have a 14mm key nor could i find one so i locked 2 nuts on a 14mm bolt and used a wrench( its also really in there and i had to use a wrench propped against my leg to get it loose...

Remove all the 12mm bolts from around the housing along with the bolt that holds in the reverse gear shaft(its on the front of the trans on the underside)....

There is a 72mm snap ring that will be visible once the 14mm plug is removed, use a pair of snap ring pliers to prop it open as you pry the case apart using the convent leverage point as supplied by honda
(my picture of it got corrupted but its easy to figure out)
next remove the oil diffuser (dont know what its called so i made up a name, its just a plastic tray and it pulls out)

there are two 12mm bolts that hold the reverse fork in remove those along with the reverse gear and shaft...

then pull the gear sets and shifter forks out and your left with just the differential and ring gear...

You will need to pull the bearing and speedo gear and ring gear off the differential, but you need a press ( i took mine to a local shop it took about 20 minutes to pull the bearing and gear and put on new bearings and the speedo gear) And yes get new bearings, there about 40 bux a piece at napa and they are not sealed as they appear, thats just a dust guard.

once everything is pressed on the differential you can throw it back on along with the gears, and scrape the old gasket off the case, replacing it with ultra flange II from honda. button it all back up and your done! not so hard now was it??

And as always im not a professional nor do i claim to be, so im not responsible for what you do wrong:mangel: But i was able to do this in my studio apartment without a problem.

You might want to add in the end of the thread how this bolt comes out so you can make sure everything pops back into place when putting the trans back together. You don't want to skip this step.

That huge ass bolt pictured above has to be removed so you can slide some things into place when putting the tranny casing back together. I think it is the top of the gear sets that slides into a groove just directly underneath that bolt if I remember correctly.

The bearing at the top of this pic above the gears sets into a groove below the bolt we are talking about. I think it is important to the bearing life. I don't remember if it is the left or right gear set that we are talking about but it is one of them.

prolly should mention that unless they have a press they will need to take the diff to a shop, so this wont be a one day deal more than likely...just a thought...


but great writeup!!

i didnt time it its all very easy as long as you have the tools on hand (which reminded me to put a tools list) and i have never done this before

thanks!!

There can be but i work for a company that does tolerancing for a living so i checked everything at work and my lsd was the same size as the oem diff so with a couple other calculations i was able to see that it didnt need shimmed. some might, you just need to take the hight of the lsd, the bearing seats and all measure it all up and do the same to the lsd and if they dont match up buy the shim that adds the right height

Oh I missed that. We had alot trouble getting it to snap into place. We had to pull the casing off a couple times to get it to snap in when putting the casing back on.

i ended up leaving the plug lose, putting the tranny in, pulling the plug off, idleing the engine in 1st, and it snapped right in so i re installed the plug
