If you don't have a GMC, the prices are pretty good now and lots of them available. We've only had ours for about 18 months and love it and the community. If you're into cars or/camping/traveling, and can afford it, go for it IMHO.
The 4l80e is a modern electronic version of the th400 with a 25% overdrive. I was looking for a complete package with low end pull as well as low rev's at cruising speed for the enhanced mileage. The motor can be bolted to the original th425 with a simple adapter but you sacrifice either hi or low speed performance without the additional gearing. Of course doing it the th425 is a much simpler and less expensive way and probably within many peoples ability. And I'm sure will give excellent results. I've never followed the norm, always looking for a better (hopefully) way and not being afraid to give it a try. Maybe off bubble a little Laughing

, who knows. Anyway, it's the approach I've taken and time will tell if it's right.
I'm running a 215/85/16 tires so the rpm's are slightly off the more popular 225/75/16.

215/75/16 tire;

55 mph 1869 in OD, 2492 in direct
60 mph 2039 in OD, 2719
65 mph 2209 in OD, 2946
70 mph 2379 in OD, 3172

225/75/16 tire

55 mph 1939 in OD, 2586 in direct
60 mph 2116 in OD, 2821
65 mph 2292 in OD, 3056
70 mph 2468 in OD, 3291
