Sparky-(Admin) 21,318 #2 Posted February 13 I dont think you want to mix motor oil with ATF…someone here will chime in with what type of ATF is correct for your Sunstrand Hydro pump Share this post Link to post Share on other sites
kpinnc 12,062 #3 Posted February 13 ATF is far better in a Sundstrand. 3 Share this post Link to post Share on other sites
squonk 41,118 #4 Posted February 13 Older Sunstrands used ATF. Around 73 WH changed to motor oil. Put in what type oil you took out. 2 Share this post Link to post Share on other sites
pfrederi 17,739 #5 Posted February 13 Changing requires multiple fills and flushes, wastes a lot of product, time, and money. ATF works great in older sunstrands. Share this post Link to post Share on other sites
