So I was reading through the FAQ about the tranny fluid and it says to use only ATF +3 or ATF +4. Now my thing is, when I did the tranny fluid and filter change on the weekend, I dumped Mobile 1 ATF D/M into the tranny. What are the consequences if I continue to use this?

 

It is possible that the transmision could slip or shift hard. I wouldn't be surprised if you did experience that. If you experience any of that, then go ahead and change it. I've heard chrysler transmissions are finicky with the trans fluid.

 

Its not slipping, nor is it shifting hard (aside from the usual hard shift from park to any drive gear, but it did this before..). Nothing any different than before. If anything it's shifting better, but that would be because of the new filter. I'm also pretty sure the overdrive solenoid is gone, which also has the lock up solenoid on it, so that could be why it's hard into the drive gears when I shift from park
