Trans and Diff Oil Probably Wrong

Just received documentation of what was used for 1200 run in maintenance.

Oil For Manual Transmission 83-22-7-533-818

Rear Diff Oil ZL90W Limited Slip


I don't see either of these two oils as correct specificaiton according to this thread.

Service rep at BMW tells me the Manual Trans oil is MTF-LT-3 and the ZL90W is what is put in M car rear diffs.

Sounds like he's wrong and he's let me drive this car over 500 miles with the wrong spec oils (motor oil and filter checks out with this thread as correct).

Any damage from this?

In addition to changing out the get the correct oils, is there anything else I should do?
