Odd feel as decelerating, popping?
My 2000 A4 trans am has been doing some weird things thepast 2 weeks. Note this is with 3.73gears.
If i'm doing around 70-80 and i back off of the gas I'm getting some popping every now and then that I never seemed to have. It seems like with the 3.73 gears the engine does a lot more work slowing the car down since it's higher inthe RPM range.
Also, starting around 45 mph dropping downwards to maybe say 20.. in 3rd or D.. I notice mycar almost making faint "putting" sounds, and almost feel the car "bumping" as its doing this.
I can't figure out what would be cuasing this, but some insight would be nice as im worried something is starting to really go wrong. thanks guys!

It's more fun if you have a cutout open. I love going down a long hill, foot off the gas and the windows down. Mine will talk to you all the way down. Almost as much fun as going down the interstate with the cutout open and the cruise control on. Then hit the +increase speed button and listen to it romp! Its normal just don't go down shifting to speed brake the car or you'll burn up the bands in the A4. Are you still running the stock stall?

Gotcha, how much down shifting would be bad, I've done it before sometimes.. not too often and never at aggresive speeds. Rather how would I start to know if the bands are going?

You take off and when your tranny gets warmed up you loose 2nd or 3rd gear. It was alright when its cold but goes away when it gets up to operating temps. I would NEVER downshift a 4L60E.
