- Inspected and found – Found code P0750-low/reverse solenoid circuit was stored in the transmission control module (TCM). The code was not a current code and the problem was not occurring. Drove vehicle and transmission was working fine but the engine stalled while driving. Got vehicle pulled to side of road and it restarted and drove back to shop were we found no codes in the TCM but there were codes stored in multiple other modules that said lost communication with ECM/TCM. Tested related voltage supplies and ground circuits which were all OK. At this point the vehicle went back to working normally for several more drives. Drove vehicle several times trying to verify all circuits to TCM were intact and they always tested good. During all the driving there were two other codes that would set occasionally. P0202-injector #2 circuit fault and P0303-injector #3 circuit fault. These codes only set one time each. Ultimately we found a TCM connector that had been incorrectly assembled that had moisture and corrosion in it. Cleaned connections and re-assembled properly and the problem occurred again fairly quickly. Will need new ECM/TCM to resolve the problem. After replacing the module everything is working properly.
