Getrag 265 5-speed transmission with m30 bell housing out of my e28. Same trans as is used in the e30 M3 (with different bell housing), e24, e23, any car with an m30, etc. Great shape, no problems, currently filled with redline fluid.
Don't know exact mileage, it originally came out of a low mileage (sub 100k) 733i sport (being from a 7, I 'm guessing it was never flogged too badly). I put about 10k on it in my 533i. Never had any problems with it.
