Bill D 2,248 #2 Posted November 3, 2020 10w-30 synthetic in the trans. 30w in the engine. Look for SJ rated engine oil for proper zinc content. Bill Share this post Link to post Share on other sites

The Tuul Crib 7,339 #4 Posted November 3, 2020 T😎 Check the color of your trans fluid If its amber then use 10w30 lf its red then go with trans fluid . Dont mix the two. Napa has Dex Merc trans fluid and for motor oil l use Shell Rotella T1 30 w Share this post Link to post Share on other sites
953 nut 59,967 #5 Posted November 3, 2020 While servicing the transmission you will want to replace the filter also. A NAPA 1410 or Wix 51410 filter will do the trick. Share this post Link to post Share on other sites
