Hi Steve ,
Great to hear off someone 😊
Definitely transmission oil.
I believe it is from between the auto box and engine
and can put some photos on once on the ramp.
I believe I read something that you can move the box
back enough to change the gasket 🤔
Thanks again for your reply 👍

If it is definitely transmission oil the most likely leak is from the torque converter seal. Requires the transmission to come out.

Hi ,
I had a similar leak from my S3, it was the the front gearbox seal .its not an expensive repair just gently prise the old seal out and replace with a new one .
I took the gearbox out when doing my repair, this can be done without taking the engine out.
All the best ,
