I am supposed to be getting my tranny back tomorrow. I blew all of the old tranny fluid out of the cooling lines and cooler with compressed air. Then I flushed the tranny cooling lines and cooler out using an old electric fuel pump. First I ran diesel fuel through it for about 30 minutes then blew that out with compressed air. Then I ran new tranny fluid through it for about 30 minutes. Will the traces of diesel fuel that might still be in the system cause any problems ?
