Message Hey guys, just looking for some extra input.

My TT auto isn't shifting into 3rd or 4th. Shifts fine between 1 and 2. Feels like it wants to shift into third sometimes but won't. Also if I'm in 2nd and let off the throttle at 45mph, the engine drops rpm like I put it in neutral then when I give it gas, it grabs again around 3-4K.

I set my TPS and reading .44V at idle. It was reading .48V.

Trans isn't throwing any codes and don't have any faults when going through the trans diagnostics procedures.

I've disconnected my ALC and that didn't do anything.

I changed my fluid and filter about a year and a half ago. Only put a couple thousand on the fluid since. I will be changing fluid and filter again soon. The fluid color is still red and not brown. It also isn't low on fluid.

If changing the fluid doesn't fix it somehow, I'll be dropping the trans to see what's going on and will follow the FSM procedures. But before I do that, am I missing anything else?

Thanks.
