2009 Mazda 6 Diesel 2.2L OBD P0704 Code $07E8 - Diagnosis and Repair Cost

Model: 2009 Mazda 6 Diesel 2.2ltr Fault Code: P0704 Posted: 2019-02-18 05:27

Hi everyone, I'm looking for advice on a recurring OBD fault code: P0704 with value $07E8 on my 2009 Mazda 6 Diesel (2.2L). I cleared the code three weeks ago, but it has returned. This is a generic P0704 code related to the transmission control system. Has anyone else experienced this issue? What are the common causes and potential repair costs? Is it something that can be fixed with DIY skills or does it require professional diagnosis and repair? Any insights would be greatly appreciated. Thanks in advance! Don
