Hi, yes it feels firmer..like it grabs or jerks a bit..which it didnt do before.
(note: The fluid was dark after changing out the first 2 quarts with the GM fluid...so far have changed out 4 quarts using GM)

So perhaps I'll just exchange 4 quarts using Maxlife, instead of just the 2 quarts in the pan. Not sure if I want to drop the pan again to check the filter.
