So my dodge has been driving perfectly fine but this morning I start my car and put it in drive and it won’t move! I can put it into any gear but it won’t accelerate??? No check engine light ever came on, or any light.... I always get my oil changed and make sure all the fluids are checked. So I have no idea what to do, google search says it could be the transmission but I pray it’s something more simple! HELP
