    F23 gearbox compatibility?

    Gents

    Clear up some confusion here as I'm the receiving end of some conflicting advice. The F23 gearbox as fitted to the Astra GSi turbo, is pretty much unique to that car (aside the Zafira GSi) although somebody seems pretty confident the 2.2 boxes and earlier Vectra V6 box are also compatible?

    Also, GSi boxes... there were no marked changes during the build, no revisions to mounts, internals, gear linkages and so forth? So, all GSi turbo should have teh same box fitted, regardless of year?

    Cheers

    The earlier V6 Box will fit onto the engine but it won't mount to the car as the V6 Box isn't a top mount gearbox. whereas the F23 has a top mount. somebody correct me if i'm wrong but i'm pretty certain i'm not

    As said in FB dave, The gearbox is the same through all the zlet range (coupe turbo, Zafira gsi and the sri-t) But the one from the 2.2 wont fit due to the starter motor IIRC.

    Cheers chaps, conflicting advice now sorted so the hunbts begins for a box.

    On that note however, 72,000 miles on a car with full service history and regular gearbox oil changes, and yet it would appear the diff has gone already... I find that a bit worrying to be fair, especially when F23's are still being used in 350bhp+ cars. Will be very interesed to see what's gone wrong once it's out the car.

    Cheers

    the Later 2.0 SRI box will fit the ZLET too (X20XEV) from about 1999.
    They only ran for a couple of years on the F23 as the 2.2 replaced it.
