Anyone know the best 5-speed automatic transmission that would bolt up to my 1981 5.9L Isuzu? It's in a 28' motorhome currently with an Allison AT540 4-speed. Is there a 5-speed that would bolt up in place of the 540? Does anyone know about a stand alone wiring harness for the conversion?

‘81 Airstream,

Does your engine have an SAE clutch housing? If so, probably a #3, most truck trans’ that are suitable adapt to that.
