Currently -2. My 99 nbs starts fine but my tranny hates it. 100% fine when warmed up or not fucking sub zero out.. likes to shift like its in tow/haul. I assume my tranny fluid is thick from the cold weather. 168k and tranny flush and filter 10k ago. Any additives I can use to help it out?

Not really sure of any additives to use that would help. My subie tranny shifts like shit until it's warmed up too.

Nope, that's just kinda nature of the beast with these in the cold. BTW, just be prepared in case your trans decides to go. Flushing a trans at that high mileage rather than just dropping the pan for a fluid/filter change has a high probability of killing it. Not saying it will happen, but I've seen it happen on 4 of my buddies trucks now
