Okay so here's my problem. I have a 2015 Hino 195. Transmission light came on blinking check A/T. I pull the transmission pan change the fluid the filter looks nasty I change the filter also. The truck was in limp mode and will not come out of limp mode. The indicator on the dash telling me what gear its in disappears and then it shifts really hard when I pull it out of park to put in drive or reverse. Also the transmission fluid is not getting hot or warm. Maybe it was due to the filter being clogged? Is there a way to get it out of limp mode? I have no check engine lights or anything on everything is off except for check A/T keeps flashing.
