Nemiga.com used to list a couple of F40 component diagrams for the Opel and Vuxhall with the part call out descriptions as well as some part numbers, but now it looks like their catalog section isn't working (good thing I copied the info to excel and saved it).




Awesome! Thanks!
RockAuto lists that part number for the G6 and Buick apps; 2006 G6 only
Summit also shows it, and lists it for Buicks with the MR6 transmission.
Based on those two facts, I think it's a solid bet this is for the 0.62 sixth.
Now... how to find the PN for the mating gear?
My former roommate is now a dealership parts guy, and he couldn't come up with anything, even giving him that number.

From this information below from CariD and the 0.62 ratio, the other gear should be 38 tooth. I looked at all listings on CariD for GM manual transmission gears and didn't find any 6th gears with a 38 tooth count.

Inside Diameter: 1.39"

Outside Diameter: 4.191"

Here are some active parts listings for a 2014 Buick Verano. It doesn't show the needed gear, but it give you a lot of the other part numbers and reinforces my comment about gear part numbers being hit and miss.

Really enjoying the build thread guru.

If I can help anyone with gearbox bits or part numbers I could try a Vauxhall dealer over here.

Thanks!

It would be really helpful if you could reach out to the Vauxhall dealer and do some part # searching!
Transmission # 55561696, 95518589, 55582837, 55593607, 55577502. This should be for a 2009 Vauxhall Insignia with the A20DTH diesel engine and the 3.091 final drive. If there are other transmission part numbers, those would be helpful to know as well.

Part #s for:
3.091 final drive ring gear
3.091 final drive upper main shaft
3.091 final drive lower main shaft
0.62 6th gear on the input shaft (should be 12787428)
0.62 6th gear on the lower main shaft

Thanks!

Hmm...give me a couple of days. I work with a Saab master tech (yes they still exist!) in my Air guard unit. He might be able to find something.

Thanks! Any information would be helpful.

Sorry, lol...It's funny, I see him about everyday, and now that I need him I haven't seen hide, nor hair of him. Still on my mind though!

I tried Vauxhall.

Unlike all other models, the insignia does not have the gearbox parts broken down into individual components. Not helpful. Since none of the components you listed could be located directly, I then tried entering the part number for the 6th gear on input shaft (12787428) and that part number did not exist on the system either!
