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.

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.
