I have a 2009 4.0 V6 five speed manual mustang, and one day my clutch gave out. im no expert in the mechanic department, but i love my car an i know a lot about it. well i took it in to get a new clutch, it cost me over 900 dollars total. as it came time to pick my car up i hopped in and turned in on, and it sounded like it gralled at me. its sluggish when i take off, when i switch gears it take and extra second or too for the gears to go into place, and if I'm in low rpm the cars does the same gralling noise. when i got to high speeds and let go of the gas the car jerks really bad. thats whats wrong on the outside. inside the AC stopped working, the engine light is on fallowed by a wrench light, and my cruise control will not turn on. my car is brand new only had it sense the summer with 46k miles on it so before i took it in everything worked perfect on my car and after the clutch repair all of this happened, can someone please tell me what this guy did to my car??? knowing is half the battle and i don't have a clue.
