I'm looking for a f40w gearbox, only problem is I can't seem to find what car these were fitted to.I've found f40 gearboxes on eBay but it doesn't state if they are wr or cr.Any info would be great :)

These are normally in a Signam or Vectra sri t or oil burnners. I think. It's a F40 in My Vectra Turbo

Yea found out its the f40 (3.55) I'm looking for.Question is now, can the 6th gears from the f40 fit into a f20? Or is it a case of get one and find out?

I doubt it highly, as the F40 is a three shaft setup and the F20 is two shaft, stuff will most likely be very different. I mean there has to be 20 years minimum between designs etc.

No harm in trying, but I wouldnt hold out hope.

I know about the 3 shaft design, and I've found a pdf with each gear layout(route) and the 6th gear in the f40 takes the same route as the f20, im more thinking of shaft size and number of spines.

Are you trying to put the 6spd cluster in an F20, or put the pair of 6th gear ratios onto the F20?

Just the 6th gear inplace of my 5th
