Does anyone have any idea regarding fuel consumption and top speed difference between ATX and MTX? I was thinking about swapping my ATX tranny with MTX one, however, I have realised that ATX tranny car revs lower comparing manual one, let's say at 100km/h. It means 626 V6 with ATX consumes less. I have no idea about top speed, but top speed occurs lower than 7000rpm so that they should be nearly same. BTW, I am putting KLZE to my car very soon... My other question is what happens if I put I4 transmission...?
