Tranmission Code PO731 1st Gear Ratio Incorrect

Code came up on my 1999 GC Limited 4X4. Does anyone know what part causes the code? Thanks

Problem solved

The symptoms were no 1st gear or overdrive. Researched online and came up with a speed sensor problem. I replaced the input sensor, erased the code, problem solved. $28 33 at the dealership.

Sorry to reopen a dead thread... but GVSU, is that $28.33 or $2833? And how hard is it to replace the sensor yourself? I got the same problem

$28.33 for the input sensor.

$2833.00 would be the price for a totally rebuilt transmission and that is on the very expensive side.
