What do you think happens with the stock exchanger for the first 2-3 minutes ?

Worst case is seen in both cooling applications regardless For initial warm up period

Only difference is the rate of rise vs time

And one won't milkshake ........... Ever

Flawed logic. ZF with a heat exchanger will be using its cold mapping sequences when it's cold. As you say 2-3 minutes. LOL IN Melbourne on cold morning it will be cold all morning just not 2-3 minutes.

In the southern cold climate States no heat exchanger means in winter you could only ever be running the ZF for extended periods under suboptimal cold shift.

If I lived in NT, WA or most places up North air to air would not fuss me so much.

Anecdotal evidence and blankly saying one solution is better than the other is ill informed.

I agree that one solution means no mix of coolant and fluid ever however it s not without its potential side affects.

Hmmmm.....you know he is a tuner mate and has 50,000kms of experience with air to air ;)?

I have heard certain people can use the Xcal and speak to the ZF and see if they like a heat exchanger more.

And how do you know I'm not engineer? Or a oil technician?

Sounds like the point I'm am trying to make is lost on most in this forum.

I run oil to air for 20k and only issue is it can flare 4th when really cold but after 5 mins its all good. Never over heated the trans with a fark load of heavy driving. Best effort Full tank= 187km's
