I have had a loss of power in my chevy 2500 silverado.....6.5 diesel.....I cant even feel the turbo lag....its wierd so i checked my tranny fluid and it was very low so I put a qt in and i cant even tell if that did anything. I still have a power loss but dont know if it is something else..It is like the engine is struggling to get up to speed...let alone hills etccc. If someone could help me out here I would appreciate it. Thanks
