Transmission problem?
Transmission problem? I posted this in the transmission forum earlier but as this is an lt1, I will ask it here too.
I've got a 97 LT1 A4. I have had this car for about 5 months and the transmission has shifted and worked great so far. No check engine lights or anything. The car is a 3.23 gear but on the highway, I am running almost 2500 rpm at about 76-78 MPH. According to all the charts and math I have seen, it should be running between 2200-2300 at that speed. According to the charts, if my rear gear ratio was about 3.50, my speed to rpm would be correct. This morning I took the cover off the rear and counted the ring and pinion teeth and I have 42 - 13 confirming there is definatly a 3.23 in the rear end. Does this sound like there could be a problem with the transmission causing it to run at a higher rpm than it should or is this normal? What do you other 3.23 A4 guys run at those speeds? Anybody have any ideas?

Yeah, It seems to be locking and unlocking correctly. At least it does at lower speeds. I can't tell if it is or not on the highway. How much of a drop in rpm would you get?
