Transmission shifts to a higher gear when going half throttle between 35-50mph When cruising between about 35-50mph if i give it about half throttle the rpms go up and the transmission seems to shift into a higher gear and it bogs down.
I don't know if it's related but it shifts hard from 1st to 2nd too unless you're taking it real easy on the throttle.
Other than that, the transmission shifts great.
I just purchased the car, the owner before me said she had the transmission rebuilt within the last year. It's completely stock except for an SLP lid.
One more thing, I know this might be a stupid question but.. from a dead stop it shifts 4 times, wouldn't that make it a 5-speed?

Sounds like it could use some transmission tuning. If you can feel four shifts you're feeling the converter lock up. Thats not usually felt unless maybe they put a shift kit in it. Sounds typical with the hard 1-2, it's real easy to get 1-2 to shift hard. Maybe next time the pan is off check the 1-2 accumulator and rearrange the springs.
Next time you drive it you can set your foot on the brake pedal, this will keep the torque converter from locking up, see if it still does the same thing or works better.
Assuming the check engine light is not on and the TPS is good, it sounds like it needs to be tuned.

My A4 will go into 4th about 40mph. Then goes into lockup about 47mph. Sounds normal to me. If you don't want all that shifting in City driving, put it in "D".
