Introduction » Transmission » Transmission Internals » Willall Racing WR35PC GR6 Piston Clip
As the GR6 transmission wears over time the selector piston edges can become rounded off, and when they do the piston can spin putting it out of alignment and bringing on the dreaded transmission warning light. WR35PC is designed to stop this piston rotation from happening by clipping on to the centre of the piston and providing a stronger more durable edge for the selector fork to work against.
