HELP.... I bought my car used so I don't know how it's supposed to feel, but when I shift the transmission into reverse it takes several seconds to engage. It immediately goes into drive when shifted there, but regardless of where it's shifted from, reverse takes its time to engage. Is my trainy going? Is there a simple fix? Is this something that needs Professional help? I'm a pretty good home mechanic, but I have zero experience working on automatic transmissions.

Thanks for your help!!!
