Just picked this up with my son as his first car (and with his own money). First of all, is this a normal RPM for 70 MPH?


Second, I have read these have locking Torque Converter Clutches (722.6 transmission). I don't feel this to be the case because if I hold the speed constant... the RPMs will change slightly (100-200 RPMs) up or down depending on load (uphill, flat, or downhill). I have other vehicles that have a TCC lock up clutch and the RPMs directly correlate to the wheel speed. I will have to give it a little more right foot to keep speed and RPMs constant up a hill... BUT the RPMs and MPH stay constant and related. Is there any explanation for this in the '99 E300TD (other than maybe the 722.6 in this e300td doesn't have a TCC lockup)?
