I just had the manual transmission fluid in my 1M changed by a local BMW specialist shop, Orr Autosport. I used Pentosin FFL-3, which is the same as BMW MTF-LT-5.
Shifts are smoother now. Not by a whole lot, but enough to notice.
Actual fill was 1.3 liters and I got to keep the remaining fluid, which I’ll use next time I change the fluid.
The total charge was $125, broken out as follows:
- Pentosin FFL-3 ($27.51 per liter x 2 liters) - $55.02
- Shop supplies - $2.31
- Labor (0.6 hours at $104 hourly labor rate) - $62.40
- Hazardous waste disposal - $1.27
- Subtotal - $121.00
- Tax - $4.00
- Total - $125.00
I wanted to see how a tech did the service before changing the fluid myself. I’ll probably do it myself next time, especially now that I’ve seen it done. As others have said, it’s a very simple project, especially if you have the right equipment. In addition to a lift (nice to have but obviously not required), the tech used a small pump that attaches to a 3/8” drive ratchet (air or battery powered) to pump the fluid up into the reservoir. It made the job very clean and easy. Here’s the exact tool he used; it’s part #70910—the second product on the page. The tool comes with the clear hoses and a plastic carrying case.

This Australian company makes tools for other companies, so you might be able to find the tool under other brand names, as well (see
here for a list of companies they make products for). A quick Google search (“PBT 70910”) shows you should be able to get one of these for under $100 USD. I’m sure other companies make similar products, as well.
Sidenote: If you live in or near Minnesota and would like more info about Orr Autosport, send me a PM. I was very happy with my experience there. Sidesidenote: They have an E30 M3 and an E36 M3 Lightweight in their lobby. They also have an iRacing simulator for customers. :)
Every day I love my 1M more and more.
