Technical M32 Gearbox, new bearings and wrong oil!

[omryd]

Hello everyone.
I had my M32 gearbox bearings done with the new endcase and the bigger bearings, two weeks ago.
EVerything seemed fine until I felt the gearbox was a bit too notchy.
Did some digging and found out they put the wrong oil in the box.
What is required is the Tutela Matryx, they put in the Tutela Technyx in the box.
I went right ahead and ordered 3 liters of Fuchs Titan sintofluid which is the go-to oil for this box from what I can tell online.
I've driven about 500 miles since the rebuild. new oild should arrive in a week.
Should I be worried I damaged the rebuilt gearbox?

I don't know about any potential damage BUT IMHO I would of gone straight back to the peeps that did the work and put the 'wrong' oil in and left it for them to sort..

It's fine don't worry.

But go get a better oil like redline or torco

Interestingly Technyx appears to be a higher spec oil (GL4+) vs Matryx (GL4) with the same grade i.e. 75w85. Shop4parts recommend Technyx for all GPs so are you sure you have the "wrong oil"?

What spec oils are allowable per your handbook? Mine suggests FIAT 9.55550-MX3 is the right oil, if so Technyx meets that: https://www.pli-petronas.com/uk/products/automotive-functional-fluids/petronas-tutela/tutela-technyx
