why would my car only go in revers and it is leaking fluid from bell houseing

i have a benz that had that problem,,but it was a transmission shifting module,,or voltage plate,,i dont know if this helps or not,,,also torque converter it sounds like,,yes im concerned you will have to get a mechanic,,prefferably a friend if you have a mechanic friend,,that will be honest,,,and tell you what you need to do

Don't try to drive it while low on fluid, more damage WILL occur!!! Transmission will need to be checked by a mechanic to determine exactly what the problem is! ADD FLUID as needed BEFORE DRIVING it to the repair shop only! May need a tow truck.
