*Let me start this off by saying, yes I know that the M5OD takes Mercon V ATF, and that you should go with what is recommended by the vehicle manufacturer
*I'm not condoning using the incorrect transmission fluid, I would just like this to be a discussion on what people have tried and their results
*Please don't reply to this thread if you're just going to say to use Mercon V because Ford says so, unless you have an argument to back it up as to why Mercon V is superior to all other fluids in this case; other than just because Ford says you should use it.
With that said, I stumbled across a post in a forum here recently where someone said they switched their transmission fluid out in their M5OD from ATF to 0w-30 full synthetic engine oil and they claimed that it helped with noise and shifting issues. It got me wondering what other fluids may actually be more suitable in a manual transmission such as the M5OD than an ATF? Like syncromesh, GL4 gear oil, engine oil... etc. I've even heard of a few people putting automatic transmission stop slip additives in manuals with positive results. One guy even said his local transmission shop claimed that all manuals should use 0w-30 engine oil, and because of this he has used 0w-30 in the transmissions in their manual cars with no issues. After doing some research, it just got me wondering... is ATF really the best fluid for a manual transmission?
I think it would be cool to have a discussion for people to input their experience with using different fluids in the M5OD.
