My mazda protoege automatic transmission shifts very jerky. How can I fix this?
are you sure it is the transmission? have you looked at the transmission fluid to see if it is burned, brown or smelly or low? I'd start there~ would consider a vacuum problem with the throttle positions sensor~
how many lifetimes has this drive-train see? in other words how many miles on this?
add some additive when your changing the oil in the trans it helps sometimes not as often with something major
