is TCM faulty? I have code p0730 and code 0894

 

On Motor Electronics 9.7 (ME 9.7)I have code p0730 and on transmission (VGS) I have code 0894. Do you guys think something could be wrong with my conductor plate? Please let me know and I would be happy to try you guys out and ship out my unit. Hope to hear from someone soon

Both P0730 & P0894 are TCM related. The ME9.7 is the ECU of the vehicle. Whereas the 722.9 TCM is physically a separate unit.Neither P0730 or P0894 are directly supported. However it's possible that these diagnostic trouble codes are caused by faulty sensors. Specifically Y3/8n1 & Y3/8n2.Scan the vehicle for trouble codes. If you see anything mentioning Y3/8n1 (turbine speed sensor) or Y3/8n2 (internal speed sensor), there's a good chance those sensors are faulty which we can rebuild.Additionally make sure the transmission fluid and filter were recently serviced and that the solenoids themselves are not defective.
