Hi. Has anyone changed their transfer case fluid and could provide some insight on their experience?

I used ISTA to open the oil chambers and I only managed to get 150 - 200ml even with a small hose. Maybe I need to use a hook or different tool. I am also not sure if I am supposed to reset calibration after the fluid change. I feel there is barely any information out there about this service for our cars.

Thank you

Fcp euro sells a perfect bent metal tube for that. Works wonders on transfer cases and diffs.

What are the commands in ISTA for this procedure?

drain, suck, refill - takes about 500ml.
I used soft hose, small diameter with large syringe
nothing to reset with ISTA
