A 2005 Saturn Vue experiences erratic ratio control (gear position) and ultimately sets a trouble code P1882. Once the code is cleared, the transmission starts to shift again, for a short time. The code then reappears and the unit returns to a fixed gear position.
After it was determined that the issue was not computer related or valve-body/solenoid related, the transmission was removed and disassembled. Damage was found in the drive variator (pulley), and there also was seal damage.
