Mike_eash 59 #1 Posted August 13, 2023 I decided to drain my transmission fluid on my charger wheelhorse it has the automatic hydrostatic tyranny. I have read that if it's red or pink it's type A if it's brown it's regular motor oil. Can anyone confirm this? I have brown in mine and I know it's important to put the same back in Thanks Share this post Link to post Share on other sites
kpinnc 12,359 #2 Posted August 13, 2023 You are correct. Red is ATF. Brown would be 30W motor oil. Share this post Link to post Share on other sites
squonk 41,291 #4 Posted August 13, 2023 A hydro with engine oil in it should have 10w 30 or 40 in it. Not straight 30 weight 1 1 1 Share this post Link to post Share on other sites
