new to me 300tdt.hey that rhymes.anyway.the car will roll backwards while in drive idling on a incline or hill.just lightly touching the accel pedal will hold the car.this does not seem normal.i have checked tranny fluid level seems ok.any ideas?

I'm really tempted to write a limerick in reply, but don't have the time right now.

Your car is completely normal. These cars have a "loose" torque converter and the engine idles at very low RPMs. As a result they have almost no "idle creep." It will just barely move on level ground, and anything that qualifies as a slope will cause it to roll back.

BTW, don't use the gas to hold in place when stopped uphill. Doing so can overheat the transmission and damage it. Use the brakes to hold the car in place.

thanks jc.i thought it a bit strange considering the tranny displays no other indication of a problem.the car runs great!very fast for a diesel
