yes. and this transmission is CVT. nothing solenoid B or C. which exists solenoid drive, driven. the results of reading the literature show this.##############the microprosessor runs a diagnostic program to detec an internal fall when power up is commanded. the only requirements are voltage and ground. the control modul detects an internal write malfunction. the control module detects an internal cecksum malfunction.
