I have a 2010 Acura RDX sh-AWD 2.3l turbo....just did a tune up (spark plugs, coils, knock sensor, oil change, etc...) and changed a couple front end parts (front sway bar, half shaft right front, tie rods outer left & right) to all of a sudden after about 10 miles of driving the transmission went bad. The shifter goes in all gears but no power to the pedal at all. When put in park a loud winning noise and car also rolls while in park....an ideas??? Is the transmission shot or is it possibly something else.... please help

 

First thing I would do is check the transmission fluid to
determine if there is a coolant contamination.

 

And definitely check that half shaft.

 

Hey, delete some of your old messages so I can send you a response.

 

In case I forget to check back, I suspect the issue is your half-shaft was not properly installed. Either the mechanic didn't put the c-clip on the new axle, or didn't push it in all the way to where the it locked into place. Either way, the symptoms sound like the axle may have shifted too far out to where it's no longer connected to the transmission output. I'd recommend taking it back to the shop asap and don't start the car in anything other than neutral (really, don't start it at all unless you absolutely have to) to prevent any further damage.

 

This.
