transmission will not shift into all gears after check engine light comes on
when the check engine light comes on after it has warmed up the trans will not shift into 4th back to park then you lose first gear and car will start in second gear and only shift into 4th some times
there are no vaccuum lines so it most be electronic and there doe's not seem to be any down shifting happening ,is it an electicail moduel or what is the cause of this probblem
