tranny/torque converter problems????

**red96** · 03-28-2011, 10:10 PM

i have a 96 trans am automatic with some mods. intake, headers, straight pipes, minor tune and a b&m power shift kit. the car has been amazing for months. now all of the sudden i start the car let it warm up and when i put it in drive or reverse it bogs down and seems like it has a misfire. if i hold the brake and let it bog the check engine light comes on for a multiple misfire (p300). i changed the spark plugs, wires, alternator, and the problem continues. when the car is in park or neutral there is no problem at all, it idles perfect and i can rev the hell out it. then when im crusin down the highway steady throttle and go up any incline it almost hesitates like its not getting enough fuel but if i gun the throttle it downshifts and acts fine. im totally confused. evry mechanic i have talked to said "oh its your plugs" or "its your fuel filter or maybe your wires" well i changed all that and i still have the problem lol. could this be a tranny problem or maybe my torque converter? any help or suggestions would be greatly appreciated. thanks in advance.
