Picked up a MINT ‘22 XLT302A 4x4 3.5EB CCSB. 69k on the clock, perfect maintenance history at local Ford dealer. I know the 10R80 sucks, I didn’t wait on a ‘23 because I got a good deal on it. That being said, I know this won’t prevent CDF failure, but planning on sucking out 4/5qt of ULV from dipstick and replacing with exact amount new ULV plus 10oz of LubeGard Platinum?????? Truck shifts great but has a minimal shake in 10th gear at low RPM. Don’t believe it’s an issue as much as I’m trying to be proactive. Thoughts? Anybody done anything similar? Gentleman who owned it used it to haul golf clubs, never had a trailer behind it.
