I have heard of a problem with the 00/01s with the 2nd gear syncro. Are there any reports of a problem with second gear on the 02/03 models.

Thanks

 

Yes. The '02-'03 2nd gear set may be marginally better, but there are still cases of grinding. Transmission oil selection seems to be key in avoiding the grind into 2nd gear. Redline MT-90 works best for me.

 

The explanation we have been given is that it is a 'stacking tolerance error' where all components of a gear set are in spec but the assembly is not. It is not actually the synchro performance but a tolerance problem that allows the sleeve to push the gear into engagement before the synchro has had sufficient time to slow the rotation. Bottom line.. it grinds.

The problem was supposedly fixed in the newer boxes and those with the TSB replacement parts, but results are spotty. Apparently these clearances are slightly different in every box and affected by temperature so some grind while others don't. Ambient temperature, lubricant, and usage will also affect how often and when the gears will grind.

 

Is there anything besides chaning the fluids that will FIX the problem? Are there any TSBs or warranty issues?
Thanks for all your help!

Yes, TSB 55. I did it from the dealer but the 2nd gear still grinded occasionally.

 

I have a 2003, and wonder what i should do if i continue this problem after fluid change?

 

Go and complain.. the car should be covered under warranty. Just don't set your expectations too high, Honda has not been real good at taking care of this issue.

 

cdlena,
Where'd you here about this tolerance stack-up problem? That's information that's not likely to make it out of the particular engineering department that designed the tranny. Maybe. See, where I come from (IBM; tape drive development/mechanical) any problem that arises out of a tolerance stack-up is a big deal. That kind of stuff is supposed to be worked out before the product is released. I mean, that's what tolerance analysis is all about. Seems to me that if Honda fudged a part/assembly/whatever, it should most definitely be covered under warranty. Regardless of what the dealer may tell you. People don't pay for stuff that doesn't work. I'd be getting in touch with Honda customer service. Forget the dealer. Have Honda tell them to fix your car.
