S1 Evora - reverse lockout collar - how does it work?

[r3nault 15]

Hi all, I have a 2010 NA Evora. Just bought a GRP GG shifter knob - noticed the OEM one in my car doesn’t have a grub screw and it just unscrews off. It does have the spring inside the centre.

What I’m wondering is what role that spring plays in pushing the reverse collar back down? When I install the GG knob, the collar stays up so reverse can always be selected, while first is difficult to get. Of course, it’s easy to just push it back down again. But I also noticed when there’s no knob at all it still doesn’t spring back down.

Is this normal? Does the little spring in the OEM knob somehow cause the spring action back down?

PS. Take it easy on me, I’ve got no chance of being trusted to pull the entire interior of my car out!

Does this help?

Looks like the spring is required for any knob installation to me.

Yes. The spring is there to push the collar back down. 34/34a clips into 35. 35 is pushed down by 29 but without 14 or 44 29 has nothing to push against.

Thanks both! Does help. I realised my description was wanting for an important detail, which is that I did put the spring inside the new knob but it didn’t have the intended effect. But I’ll have to have a bit of a look again later and see if it just needs a bit of a stronger spring for the new knob
