Never ever heat a transfer case. Case aluminum with a steel plug you're just begging for a Crack in the tcase. Very risky. Glad you got it broke loose. I personally would have used penetrating oil an Allen key and a hammer and gently pecked on it until it broke loose hard to do at that angle but it can be done.
Why you using dexron 6? The manual says dexron 3 for that year.
It is compatible, can’t get dexron 3 anywhere where I live
