Automatic Transmission Gear Indicator problems of the 2007 Suzuki Reno

1 placing the vehicle in any gear causes this particular problem. My vehicle began to show symptoms at about 30,000 miles. 2 when the vehicle is placed in any gear, a diagnostic code is set that only allows the vehicle to operate in drive or reverse. Lower gears are not allowed to operate when in this mode of operation. Initially the failure was when the vehicle was cold (below 60 degrees f) later the problem occurred frequently when the vehicle was started. The result is very sluggish acceleration of the vehicle which could result in a crash after pulling into traffic. 3 replacement of the "prndl" or park-neutral switch or transmission range switch ( all names for the same part) corrected the problem. Note: the transmission repair shop noted that this was a common failure item on many vehicles and the dealer where the replacement part was purchased had 3 in their shop (for the same problem) at the time the part was purchased. The dealer also told the transmission tech that they replaced about 3 of these switches per week on average.
