Q: Replaced transmission cooler but its still not shifting could this be because it's now in limp mode

asked by on September 25, 2016

I pulled into gas station and noticed transmission fluid running out underneath called mechanic he loaded it up took it to shop found it to be the transmission cooler and changed that but it still wouldn't shift when i asked what he thought it might be he said he didn't know so I told him to stop working on it. It wouldn't throw a code but a transmission mechanic thought it was probably an external issue like solenoid or sensor changed solenoid still wouldn't shift could it be pressure switch
