Hi first post here. I've done a ton of research and can't get a clear picture of how to do this properly. So I'll get right into it. I have 4 auto trannys:
4T65E (03 century 3.1 100k) commuter
4T80E (03 Deville 4.6 100k) wifes commuter
4L60E (98 Jimmy 4.3 108K) 4 wheeler/hunting vehicle
E4OD (96 F-250 5.8 60K) boat puller
I'm looking to change tranny fluid once a year (yes I over maintain everything) with pan drops instead of every 30 k as i don't put that many miles on any of them yearly but its just easier to remember.
My questions are:
1) Would it be ok to use a multi vehicle fluid like maxlife or Mobil 1 in all of them? (Don't wanna order Amsoil) Or would I be better off using the vehicle specific/back specd fluids (merc v and dex vi)?
2) Best fluid brand that isn't amsoil?
2) Who makes the best automatic transmission filter with regard to filtering abilities? I can't find any hard data on this.
3) Would synthetic, blended, or conventional make much of a difference if I am going to change it yearly anyways?
4) Is mixing different brands from year to year advised to get the different additive packages from each or should I just pick one and stick with that?
5) They have all been maintained with 30 k changes routinely. Should I just do a transmission flush on everything and start fresh?
Thanks.
