If you have those 2 codes p0717 p0700 and tried replacing the speed sensor along with tcm transmission module due to hard shifts shifting 1 and 2 gear try changing your alternator they have diodes regulators that go bad and causes transmission TCM malfunctions..if it works like my video share it thanks
