[ARCHRIVAL]

Is there someone that can tell what model xx this gearbox is for GEARBOX Citroen CX 2GE66 NEW
It is advertised on eBay UK and looks interesting if it fits a petrol turbo CX might solve the synchro issues my car has been cursed with

I looked in the 1981-85 Citroen parts manual and 2GE66 and 2GE65 are for the 2 litre engine after June 1984 (page 197 in the pdf). The GTi Turbo gearbox is marked 2GE60 and 2GE59 (page 200).

Synchros is no big deal, you can change them through the wheel arch if needed. Have you tried nulon G70 in the 'box The later 5spders are quite robust synchro wise. Mine have always been ok'ish. It would have been beaten to death when new as its a CNAN car, so I'm sure the synchros were flogged as hard as the motor when it was new.

It seems from my gearbox guru that the synchro rings themselves are not the issue it is the special treatment to the mating surfaces or the gearset that wear losing the friction component to get them spinning for the meshing

That was the early 4spders, they wore the synchro running area down on the gears. I don't think the 5spders suffer from this

GS did the same. Their synchros wore quickly. Both the ring and the mating cone wore so that both the gear and the ring had to be replaced. CX C-Matic synchros were of the same design but they are not changed as frequently due to the torque multiplication of the torque converter. Therefore they lasted longer!
