Synthtic and non synthetic fluid
I'm changing the oil on my truck in the next week or so and I've read that most guys change their spin on tranny filter when they change their oil. I had my tranny flushed and refilled a couple thousand miles ago and had the OEM fluid put in. I have some Amsoil synthetic that I'd like to put in. Does anyone see any issue with mixing synthetic and non-synthetic transmission fluids?
Thanks in advance,
Pete
