I recently just added transmission fluid, thought that would of helped the little bit of slipping and also my car is a couple thousand over on an oil change. it has 205,000 miles on it. Basically the car starts fine it will go into reverse drive and park no problem but when I start to drive it gives out. I was wondering if it could possibly be the transmission having too much fluid... not being too much oil in the engine, or my transmission is done for, I didnt really know where to start so hopefully someone on here can help! thanks guys and girls!
