My post #14 is also based on "Reverse works great" which probably rules out the converter and differential, but I always take these "subjective" descriptions with a grain of salt. For example, 25% throttle in Reverse might be more than the OP is testing, while he is giving 25% throttle in forward.
Clearly the OP's first post was not very thorough and perhaps WHTLTN2 only skimmed over the following posts as we tried to pin down exactly what the symptoms are. It takes a while to get the hang of how these threads develop. I suspect that many of us could quickly figure out many problems if we could drive the car, but instead we have to ask the OPs to try different things and hope they then describe the results accurately. It is often comes down to communication/writing issues.
I'm leaning toward an internal problem in the trans, perhaps the forward clutch or the forward sprag (which can damage the forward clutch), but have not ruled out the converter.
