I have codes P0700-Transaxle control fault, P0732-ratio error in second gear, P0736-ratio error in reverse gear, P0733-ratio error in third gear and P0841- pressure switch rationality fault. The causes are poor electrical connection and internal transmission fault on codes 732, 733 and 736. 700 has shortened or open circuit within transaxle and failure of transaxle control module. 841 has poor electrical connection, failed transmission solenoid/pressure switch or faulty TCM/ECM. I do not have much experience with transmissions so any I ideas before I dive in would be helpful. Of course the first thing I will check is the wiring harness but I need to be pointed in the right direction if that is not the problem. Any help is appreciated.
