don't always get good results. Flushing is something you can do yourself and will run you a couple hundred bucks in ATF (I would use Valvoline Maxlife Full-synthetic ATF for $18/gallon from Walmart), but if it works, it could save thousands of dollars. The other option is a used trans if you can find one that hasn't been contaminated, but keep in mind the TCM has to be initialized (or programmed) to the ECM (the same goes for getting a reman trans or a rebuild with a new TCM). So, as you see, there are several options. Only you can determine which route is the best one to go with.
