JDM vs US tranny differences?

[Chris@Rvengeperformance]

The difference in the driveshafts is only like 3/4". You can use either in either in a pinch and even on a 13t car launching hard no issues were had, other drivetrain parts break before you can strip out the yoke.


BTW, it's the front section that's different.

Yep, I only changed my front section because there was little room for the yoke to slide into the t-case (it was a 6 speed shaft on a 5 speed setup). Solid or even good poly mounts would probably be fine.

Sounds like all you need is new syncros, get some quotes from reputable 3S shops that work on these gearboxes (Ninja, GZP, 3SX, Jacks, Kormex etc).

If your transmission is grinding repeatably then you have a lot more damage than just syncros.

[Hans@GZP]

Yup. Once grinding starts, you are mashing up the expensive transmission parts. We do sell OEM synchronizers. The hard parts are obtainable, but they can take a couple of months to arrive.
