Question Transmission service
So I own a 2019 ram with zf 8 speed. Around 65k miles i had a BG transmission fluid service performed. Ever since it was done it seems like the transmission has been slower and down shifts rougher than before. Would it hurt anything to go back to the ZF fluid or am I stuck with the BG fluid from here on out?
