You have done some exceptionable work on trying to diagnosis and repair DMC Trans computers. Have you talked to PJ Grady about your work. He seems like the one who would be interested in doing the electronic upgrade. What would make this task simpler, would be to collect all of the failed units. this would provided the hoses, plugs, adapters etc and greatly reduce manufacturing costs. I do not have a failed unit. I did not install the factory trans cooler but went with an external cooler. Now I need to drive 20,000 miles. I am also very careful about charging the battery. The aberant AC may not be good for this circuit. bob
