I'm sure most of your cars lock out out of lower gears as your speed increases which is nice at certain times. But I just can't for the life of me figure out how it determines at what speed/rpm to lock you out of the previous gear. Sometimes I can't get into 3rd until I'm under 50mph and sometimes I can get back into it at nearly 70mph. Same with second, sometimes I'm stuck out until 30mph and sometimes I can get in at 50mph. So I'm curious as to it works that way?
