2000 Man Transmission problem

[SilentShooter]

Does anyone know what is involved in repairing the 2nd gear MT problem in a 2000? Seems like it's pretty typical of these vehicles from what I read on here. I'm thinking about buying a car with that problem and wanted to know the cost of getting it fixed and what all is involved.

The actual rebuild of the box is pretty easy. Anybody half decent at spannering can do it. The 2nd gear syncro part isn't cheap, in the UK you could spend in the region of £1000 to reapir it & do the bearing/seal whilst at it, bear in mind when negotiating the price of the car.

From some pics and a recent discussion on endless sphere forum. Not sure how relevant or accurate this info is. Or how it relates to our overall understanding of the 2nd gear syncro issue, then again i'm no gearbox expert.

from the photos i see where the problem is its the hardened steel coller in between the 2 brass syncros if work on quite a few honda transmissions the problem can be fixed u need a thicker coller between the 2 syncros so when it pulls away it wont pull to far apart so that it wont chip the guides also the newer honda 6 speeds have same problem but most of problems where due to crappy gear cast :P maby i should take stevos spare tranny apart that we swaped out for a mint one i serviced for him and see if i can find some parts that can be swaped to fix the problem from the 6 speed k20 family ^_^

Funny you mention the K-series trannies, I broke a few 2nd gears in them in my racecar before going to a PPG dog-box gearset. That insight is using 36 dog teeth on the collar! WOOT!!! This means you can grind away every other tooth on the face and inside the collar and make it shift like butter. Thank you so much for the pictures! Those are rare pictures to find! Do you happen to know anyone with a "worn out" gearset they are looking to sell? This would let me have all the time I want to get the machining/grinding done before taking my car down.

It appears the synchro itself didn't loose it's gear grabbing abilities at all (like how a normal synchro failure happens), the teeth on the cones look great inside and out. It wore the clocking tabs down enough so that it slows the gear and FORCES it to be clocked mid-way between teeth, so of course it's going to grind. It's like an anti-synchro now. lol Of all the places to save weight... they thinned out the clocking tabs on the synchro... LAME!

What do we think?

When I first saw those pictures, I was confused because as is said, the synchro looks fine. I'm very interested in this. I don't know anything about gearboxes either, but apparently those people do. Need more information and a better explanation of what is happening here!

So we can fix this by grinding something down? I have a spare transmission that I could play with, just need some guidance here..

Well I don;t even know what spannering is so I am assuming I can't do it lol. I figured it would be around $1500 but I have no idea

It's going to run you about $1500 either for a used transmission installed with new clutch, or having your transmission rebuilt.

Having the transmission rebuilt is probably a better overall solution than a used transmission, but may be a bit more expensive.

I installed a used transmission into Insight #2 for ~$750, but I did the work with the help of a friend.

I was told by a local shop that it would be 1400 bucks to rebuild the tranny with all new synrcos. I didn't end up doing it because my second gear only makes a sound when downshifting into it from high speed.

I was quoted huge $$ by the Honda stealership. I then went to a local tranny shop and after asking them several times how much it would be to replace my ISB they refused to give me any sort of quote... the fact that they would not do so, and that the 3 guys looked like their combined IQ's were still under 100, left me little choice but to tackle the job myself.

To do an ISB, which is something that should definitely be done ANYTIME the tranny is cracked open, is not a bad job, nor is replacing the syncro itself. The ISB costs around $25, the Syncro more. To do both should run @ $250'ish in parts and a good guess on labor should be in the $1000 range. Someone who has done this before, with decent tools, should take them about 6-8 hours.

I must a dummy but what is an ISB?

ISB=Intake shaft bearing.
