So keep it cool and keep it longer.

Hello hello,
So the stock F90 ZF can’t handle anymore than 750nm(550lb-ft) . My car was pushing 800nm (590lb-ft) on 100 octane (as per a TCU stress readout and told by my service advisor.
I had to take my car in because on 6th gear load shifts the transmission started slipping. Eventually it also started happening on 5th gear load shifts.
Anyways the dealer has ordered me a new transmission however it’s still on a shop from Germany. Meanwhile I’ve been driving with the broken transmission however if I’m not pushing it than it’s fine, even on 5th and 6th gears where it slips on load (full or close to full throttle).
Has anyone else experienced this issue on the 2019 F90 M5?
