Guess he should have only charged you for 15 minutes , huh ??
And you brought him the part , too... that saved him some time, right ??
Get the car in , on the lift , up in the air , take old part off ,
[ linkage , , shifter and switch, connector , and adjust the switch for proper alignment for both P and N , plus back-up lights....
take car off lift and make out the bill..
You did fine.... should have brought in some oil and had him drop that in while it was in the air...
