I believe the trans is in what they call limpin so you only have 2nd and reverse. This limpin mode is what set off your check eng light. You would need someone to get the fault codes out of the trans controller with a scan tool. You would need to do this first to properly diagnose the trans. It is safe to drive it this way as long as you stay around 45mph. Once you get the codes come back on and Ill try to help you with an inexpensive fix.
