Howdy,
On my 03 GMC Sierra with 163,000 miles I have:
At 70,000 miles, dropped the pan, replaced the filter and 5 qts. Mobil 1 ATF.
At 106,000 miles, did a 100% fluid exchange with Amsoil ATF.
I want the truck to last 300,000 miles plus.
I pull a 3,000 Lb. boat quite a bit, haul truck loads of wood & run it moderately hard.
Which of these should I do?
1) Drain the pan (it has a plug) and add 5 qts. Amsoil ATF?
2) Drop the pan & replace the filter & 5 qts. Amsoil ATF?
3) Do a 100% fluid exchange with Amsoil ATF?
Thanks!
