953 nut 55,839 #2 Posted May 26, 2018 You should replace the transmission fluid with the same type as it has in it presently. If it is amber colored them use 10 W 30 and if it is pink then use Dextron ATF, they are not compatible, do not mix them. The replacement filter should be a NAPA 1410 1 Share this post Link to post Share on other sites
squonk 41,367 #3 Posted May 26, 2018 (edited) For engine oil hydro's Mobil 1 For trans oil models I think it was type A which was replaced by Dexron. Edited May 26, 2018 by squonk Share this post Link to post Share on other sites
BOB ELLISON 2,981 #4 Posted May 27, 2018 Wheel horse used both transmission oil and motor oil. I have a 74 C160 that has motor oil and I use mobile 1 10w30. In my 77 C160 it has transmission oil. Share this post Link to post Share on other sites
