No engine braking in OD. Excessive shifting= wear. Higher transmission temps caused by high vortex flow in convertor = failure.

After all these guesses, do you want to know the real reason why? From a trans tech. [links]
It's very obvious if you have a transmission temp gauge (measures the tranny fluid temp). here
You can’t tell the difference between a 700R4 and a 4L60E by the oil pan as they are nearly the same. If the transmission has a large 18-pin electronic connector above the passenger side pan rail, it’s a 4L60E, as seen here. If it has a cable connection near the cooler lines on the passenger’s side, that’s a 700R4.
The good news is that either way, you win. Elsewhere in this story we’ve listed the ratios of both the TH350 and the 700R4/4L60E. While the 3.06:1 First-gear ratio would appear to be an advantage over the TH350’s 2.52:1, the downside with the deeper First is the major rpm drop in the 1-2 and 2-3 gear changes that the 700R4/4L60 force upon you. At part throttle, this is only a minor issue since converter slippage absorbs most of the difference.
The Achilles heel for the 700R4 is the TV cable adjustment. Thousands of 700s have died because this adjustment is incorrect. This leads to low line pressure that smokes the clutches. Be forewarned, this can happen very quickly.
