I have a 96 pontiac grand am se 2.4L 4 cyl Automatic. just had the engine replaced also, i drove it from Oklahoma to Texas on Friday and realized there was something wrong. when i took off from complete stop i took off extremely slow, i figured out that it was taking off in 2nd gear, when i put it into 1st i noticed the gear light next to the gear that tells me what gear im in does not come on. also when i pulled into a gas station i noticed a sensor hanging from underneath the transmission. One other thing is im having an oil leak from the oil pan please explain all this to me PLEASE i need to get back home to Oklahoma ASAP
