Hey guys, I am talking to a guy who has a bad JDM tranny. One gear is bad...possibly other things too.
Can I use the gears from that tranny in my H23 tranny??

 

??

 

I wouldn't know, but try calling ProDrive and ask them if it's possible...and while you at it, find out how are for each gears.

 

As long as u switch the gears on both the main and the countershaft, u will me fine. You can switch any gears/final drive between the H & F series trannys. If you do switch final drives...remember to also swap countershafts.

Good luck.

ps. each gear is marked from the factory by a small notch on the side of the gear. This will help with gear identification, etc.

 

you cant mix h22 gears with h23 gears. you can put all h22 gears in the h23 case, the cases are the same, the h22 gears are different thickness however. both trannys have the same final drive, countershaft and main shaft
