6 speed transmissions for M5x??

[rmosca594]

Hey everyone, silly question... Will the 540i 6spd transmission for on my M50? Found one for super cheap local

Thanks, Rob

No. The bell housing has the wrong bolt pattern. You'd have to cut it off and weld a 6spd housing on. Possible, but not very practical.

Damn that blows :/ back to sourcing a 6spd lol

I heard you can use the 6 speed from the e46 330i and m3.

The bellhouse actually unbolts and interchanges between the v8/I6 getrag 6mt units.

The output flange for e39 6mt v8 (105mm) is not compatible with any I6 driveshafts (96mm) though; so the exit flange will need to be changed along with the bellhouse;

basically unless you have a e46 m3 getrag 6mt for parts to donate to the 540i v8 trans you wont be able to use it with a 6 cylinder.

any 2000-2006 e46 M3 transmission bolts to a M50/m52/s50/s52/s54 engine.
any e60 530i ZF 6 speed or E46 330/325 late model ZF 6 speed will directly bolt to a M50/m52/s50/s52/s54 engine.

If it's cheap, buy it anyway and sell it to an m60 swap guy. Those transmissions aren't exactly easy to find and you could make a bit of money and help another e30 engine swap guy out.

E36 M3 6-speeds bolt up too, correct?

Yep, I had one in my e36 with a US spec s52.

Yep, the G420 six speed boxes from the euro e36 cars are nice as well though a little picky on fluid.(have had good luck with RP syncromesh)

Have you had a chance to try this yourself?

I'm not the only one who has done this; it's not that special or unheard of

I fit a euro E46 320diesel 6 speed attached to my m20 in 1987 e30; I was the first stateside

Oh okay. I gave you a shout last year about this very subject and asked if you had any advice but I think at the time you hadn't actually done it yet, so I was just wondering if you had any new advice or tips on the swap...

I've spent the last year racing; working on weird conversions is on the back burner.

Will be 10x racing/practice weekends by the end of year.

I don't really suggest converting a v8 6mt getrag to i6 standard bell house and tail output it as it's a pita to align the item and come up with the parts. You will need a complete i6 getrag from e46 m3 for parts donation; kind of ridiculous to purchase another 6mt for a bell house and tail output flange.

Easier to sell the v8 6mt and get a i6 6mt.

So common nowadays as any 128/328i has them all equipped

From my understanding you still need an e46 clutch, make a tail mount , modifiy the shifter and find a driveshaft to work tho right ?
