I have a 98 spec ITR tranny, my 2nd & 3rd counter shaft gears are worn out. I have called lots of Acura dealers and they tell me that the 3rd gear is nationaly back order with out date of release. Ican get 2nd gear but with out the 3rd gear it is not good. Do anybody knows where I can get it? TIA

 

Either find a used set, wait on the gear to be released, or get a close gear set.

 

are the 99 civic SI gears the same as ITR? Can I just change the 2nd & 3rd? or do I have to change all of them?

 

Yes, you can use the Si 3rd

 

How about the 2nd?

 

Yes, the B16A and US ITR trannies use the same 1-5 ratios.

 

I forgot to say that my tranny is JDM 4.7fd, Would that make a difference? or Are they the same?

 

2nd/3rd are the same fitment. 1st is same ratio, but different fitment.

 

thanks a lot. I will try to get the 3rd gear from the SI since a local dealer has the 2nd gear

 

Just make sure to use new gears, not used.
