Transmission Slip

[Hawker]

Just got my Edge back after having a new engine installed at 1,500 miles. Have noticed that if I stop on my slightly inclined driveway that the vehicle will roll back, all the way to the street if I let it. Is there maybe a low fluid level here from the major rebuild that just took place?? Or a computer chip issue perhaps.

There is at least one if not 2 other threads on this.. Use the search function.

 

You could say more info in your post when you write about it.

 

I have to assume, you are in Neutral and not putting your foot on the brake, by the way you wrote about this.

Virtually all vehicles with an automatic transmission will do this to some degree. Our vehicles just do it on a slightly lower slope than some others. Use the brakes.

Sounds normal to me.

Yeah, it's normal for the EDGE, but the CX-7, or 9 for that matter, don't do it as much as the EDGE, only on the steepest of inclines.

It's a function of the engine idle speed and torque converter stall speed.

I understand, but it needs to be recalibrated so it doesn't do it so easily.

It was done on purpose for fuel economy. The drivetrain engineers didn't like it but weren't given a choice.
