Hey everyone,

I don't post much but I lurk allot :)

Anyhoo, have a 535iA that has a manual. The PO converted it to a manual roughly 2 years ago (about 10 months after I bought it) drives fine and all but it's just where this gearbox came from that puzzles me. PO said it was from an E28 with an M30 engine.

Have a few part-numbers here which may help (I've searched all of these on realoem.com with no avail):

2600105091 This number is part of the gearbox. As in it was part of the cast when manufactured

NG004669 This number has been stamped onto a flat surface on the box (very neatly like what you'd expect from the factory).

And finally 1128517 this number is on the cross brace of the box. With a search on realoem.com it shows that it could be from a number of E28's or an E24. Though it looks like this part has been modified by the PO to suit the E34 bolt hole positions on the body.

Brief description - Aluminium, round in shape (E34 5 speeds were a 'square' shape) and both the drain and fill plugs are 24mm diameter with 17mm in-hex sockets. That's about it really. It mates onto the engine fine....and as I said it drives fine. How can I confirm where this thing comes from? :( :D :(

RealOEM shows that the crossmember is for a Getrag 260.

Also says that it could certainly be from an E28 535. Does it look like #2 here?

Aah yes, the certainly looks like it, thank you :)

Still, the numbers don't match at all... /shrug

The part number on the tranny should bet a 7 or 11 digit number. You found a 10 digit number which looks like it's something other than the BMW part number.

A BMW part number that starts with 26 would be a drive shaft part #. So you just haven't found the BMW part number on it yet. I don't know my Getrags well enough to tell you where to look for it.

Hmm, ok. Will have to get under there with a mirror and have a look around...and do my hair at the same time, har har har ;)

Ok well found another part number on it. Was on the 'back' of the box just infront of the cross-brace.
2600106090 - 10 digits, similar to the other number on it. Same result on RealOEM. This is crazy :S
