Try Lucas Transmission Fix. That mysterious bottle of fluid fixed my last transmission problem.
I used to have a 99 Mazda Protege. It took several seconds to engage into gear, after I shift into R. After I put the transmission fix into the transmission, that issue never came back.
I have a 2012 mustang V6 auto with under 1000 miles. I've noticed that when my car is cold the transmission seems to R up a bit almost as if it's a stall converter. Also it seems to take a bit longer to shift while cold. I've only noticed this from take off and as soon as it's warmed up it no longer happens. Is this normal or should I consider taking the car back in? I was just about to purchase a tune and this has me concerned enough to put that on hold. Thank you to anyone who can help.
