well first let me start by saying hello to all. this is my first post and love my suburban. my question is 2 fold the atf vi stock fluid is it synthetic or a partial blend ? i want to switch to a fully synthetic brand like mobil 1. if i decided to switch the oil over what would be the best way to do it ? can i just take it down to jiffy lube and have them plug it in to teh machine and switch it out ? or can i drop the oil pan ? wouldnt the tranny need to be droped to swap out the oil in the tq converter? i thank you all in advance for your replys.
