I have a 2016 Range Rover Sport TD6 with 53,000 miles on it. Recently it started to downshift hard, RPM rises when it downshifts between most gears. What should I check? OBD2 reader shows Code: U0447 Invalid Data Received from Gateway A. and Code: P2201 Nitrous Oxide Sensor Circuit...

Hi, This morning when I drove into work I noticed a Low whine when stepping on the gas. When I got to the Highway there was no downshift and it tops out at 120KM\h No warning lights or errors. Sports mode makes no difference or the 4x4 mode. Could it be a dirty sensor? It seems the turbo will...

Hi All! First post here after purchasing a 2003 4.4 Range Rover with 163,000 km on the clock I noticed driving it home that sometimes gives a large thump when downshifting from 2nd to first as I come to a stop. I googled this issue and it seems like a few others have reported this issue, but...

1999 Gems 4.0 - can downshift be adjusted? Manually? Also ... Since installing new head gaskets, car runs great. However, does not downshift as easily as before. Did I do something to alter the setting? Is it adjustable? Also, the idiots who "designed" the remote keys put a rubber screw thing...

Transmission will not downshift to first, only takes off in higher gears Just bought a 97 P38, the previous owner had the ECM and transmission control module replaced before giving up. Someone told him that the BeCM is to blame, has anyone experienced this issue before? The rover can be driven...
