Driving my car last weekend and all of a sudden it wasn't picking up speed anymore. The only thing that kept going up, was the rpm. Now I got the engine code on my scanner went through all the steps and checked it with my multimeter to see if it had any loss of power or open wire, The only thing left is the case right on top of the transmission i dont know if i should just replace the whole thing. pls. If anyone can help i would really appreciate it.
