Hey hi how yall doin. First, some background info.. Yesterday, my dad checked the transmission fluid for the first time (not knowing you had to cycle through gears first) and it did not register. So we put half a quart of ATF in and then noticed a transmission leak. I googled to find out it was because we over filled it. It is still dripping right now from 7PM yesterday.. is that normal? Today driving around town I noticed when you stop at a stop sign, then make a sharp turn it slips into neutral as you accelerate but then kicks back. It's happened 5 or 6 times just today. Now, Another problem. I just got done washing the car when I turned it on to see a flashing check engine light. I found out that could mean a misfire. We just replaced the plugs with XXXXX 2 days ago. Did we mess them up maybe? It doesn't sound to have a misfire at idle or rev. the plug wires are not OEM but have been there since past owner. I dont know if any of these problems are related but if you can help me with any of them, please do. 2000 Subaru Outback Legacy with 146k.
