Thanks for the suggestions. To clarify:

1. “having the same problem” does include still getting a code 24 and still binding;
2. there is no chance that Duty Solonoid C was not replaced. The mechanic did remove the rear extension of the transmission to replace it.

Since my initial post I inserted the FWD fuse. With the fuse installed I don’t get any binding and I don’t get the code 24.

Now what?
