To ASEMaster6371 jumping my vehicle means someone before me jump start the truck to start it my transmission question is before I had my transmission replaced or repair it immediately dies when put in gear and now it runs and drive great. Now the question about the pcm a mechanic said the pcm caused my transmission problem my code reader I bought I run a code reader on the system it pass on the o few seconds a 10 appear and I got codes 122,157,543 from c. The letters is from a code reader for Ford obd1 digital reader
