does that diesel ecu also work for an 4l60e ?
GM did put the 4L60e behind non-turbo 6.2L and 6.5L diesels in the early 90's, probably 1991-93 range, so there should be an ecu out there for it. Rockauto has ecu #16147609 listed for a 92 6.2L C1500, so that is one possibility. look up 1/2 ton trucks and you should be able to find more ecu numbers.
