Yes it is ATL. The entire fluid change history is on the report. This is the first time that I didn’t do a 3x drain and fill. Only ever sampled the first drain every time. This time I only did 1 drain and fill. Was planning on every 20k repeating the process
Changed the factory fill on my 3.6L LFX 2012 Buick LaCrosse with the 6T70 transmission. Did 3 drain and fills and will be following severe service schedule and change every 45k Miles. Used maxlife synthetic atf this time around
