I own a 2003 automatic V6 new edge mustang with 148,000 miles, and recently I drifted it and muddy water got all up under and inside of everything frying my alternator and making me replace my a/c pulley but the problem im having now is my car bogs and hesitates going into 2nd gear and I can’t seem to understand what the problem is, I’ve replaced the MAF sensor and put a new air filter but no solution to the problem, the car drives fine overall aside from being in 2nd gear. I can manually put it in 1st no problems idles fine, and if I manually put it in 2nd it bogs down and sounds like it’s cammed until it shuts off eventually. When driving in overdrive it idles fine and everything but when i start to drive and it shifts into 2nd the rpms drop and its shakes the smallest bit but then accelerates normally and drives fine, and also when coming to a stop if i hit the brakes a little to hard it shakes while downshifting thru 2nd and almost wants to stall out sometimes stalls out and shuts off. I’ve also checked my fluids and all seem fine I recently had a transmission flush no metal being in the fluid when changed or now when i check, no water in my oil either. If anyone has had this problem or can potentially tell me what’s wrong I would appreciate it greatly!
