Ford 5R110, I have a few customers running around at 500 hp with NO mods other than a good torque converter.

Allison 1000 6 speed, They do very well at 350/650.

47RE/48RE...Last a long time at stock power levels, The easiest & most cost effective solution.

4L80E's are not suitable for diesel applications, Even behind 6.5L's they seem to fail often, The Duramax in fullsize vans.....Though detuned still tears them up.
