Here is a Getrag 265/5, Euro 5 speed transmission, close ratio, with the dogleg shift pattern. E30 M3.
If you know, you know.

This came from a BMW independent service shop, that ran a race program. I did confirm the shift pattern and gear ratios. I also hooked it up to a drill motor and ran it for a few seconds (no oil) in each gear at 1,200 RPM. Obviously, I couldn't check the shifting, but there were no strange noises and all ran smooth. I have limited knowledge about, other than what you see. A tag on it says "Prepped, no oil, yellow Euro race car." I don't know what all "prepped" means, but I can see that the speedometer and other sensor/switch holes are plugged. I assume because you don't need those sensors on a race car.
Gear ratios to my rough calculations are about;
1st - 3.7:1
2nd - 2.4:1
3rd - 1.8:1
4th - 1.25:1
5th - 1:1

Local pick up is okay. I can store it indoors for up to 90 days after purchase. Pick up in Three Points Arizona

I'm listing a bunch of BMW parts, performance items and tools. Items were obtained from a local BMW Independent service shop, that went out of business. I have limited knowledge on some of the items. If you have questions or added information, please let me know.
I'm not a professional Ebay'r, just a working guy that sells some stuff here and there. Thus, I do not have a shipping and receiving department or a customer service hot line. I live in a rural area, 40 miles from the nearest post office. I always do my best to get items out as quickly as I can, but please expect reasonable shipping/handling times. If you do make a purchase and need the item fast, let me know and I will do the best I can to work with you.
