So I own an automatic 95 mustang and i've had it for about 4 or 5 years and have always had troubles with it.
2 years ago i had a full new transmission put into the mustang and the car started running alright, a little better than how it was running but...
My most recent issue is that when i start the car the car starts but then it goes below 1 rpm and will ocassionally go up and down if i push down on the accelerator, but if i don't accelerate the car will just die. Then when i turn it on again it starts up fine, but after i reverse out of my parking spot (just fine no troubles) and put it in drive, the cars rpms drop again. My car won't go over 20 mph for about 5 minutes. I can rev the rpms, but the car always pops a few times on it's way to getting to even 30 mph. Once my car is running for about 5 to 10 minutes, the car runs fine, but i when i start going on the freeway i press the gas pedal all the way down, but won't speed up at a constant rate, the rpms jump past 3 or 4 and the car won't speed up with it.
