Transmission always kicked when it shifted and was a little funky today it completely acted like it was in neutral while in all gears. parked it then tried all the gears reverse is completely out and all the gears d1-4 are all stuck on the same gear when driving I got it home while it was stuck on the same gear the whole time then the d4 light started blinking saw some leakage going on when I got it home but my atf fluid shows it’s at a good level car only has 120k miles on it
