I hate starting new threads on something that has already been covered, but I've been scanning previous threads and have not seen this subject covered directly. I'm going to drop my tranny pan and change the fluid and filter. 1st, what is the recommended fluid; Dexron III? 2nd, I go to NAPA for Wix Gold oil filters, but have no idea about different quality of tranny filters; any advantage to paying more? 3rd, I usually run either Castrol tranny fluid or a Mobil synthetic tranny fluid in my Fords; any reason not to in the 4l60e? 4th, on my newer Ford, there is a drain bolt on the torque converter to facilitate getting the maximum amount of nasty fluid out short of having the entire thing flushed. Is there a way to drain the TC on the 4l60e? Thanks!
