What is error code P0748?
 

Got this code in a scanner - what does it mean? Bought this car from a relative and noticed it was leaking tranny fluid at the radiator (this was after the I got the Transmission Service Required message). Fluid had been flushed before I got it and hose was not tightened completely. Gave up a '93 240 for this thing - worst car mistake of my life....could this have been triggered by low fluid?
