Thread: 4bt1t what auto?

I think you would be rite .

Your best bet would be to calculate final ratios and graph it against RPM in a spreadsheet. That way you will easily see what options are best. Even if you get a good highway ratio you dont want common speeds like 80 or 60 to be between the sweet spots in gears. In my old setup 60 was too fast for 3rd and too slow for 4th. It was really annoying.

Limited rev range, combined with limited gear ratios's

Thats why all these fandangled new diesels have lots of ratio's in there auto box

IIRC, the 345 cube V8 in a scout has a redline of 3500 or 3900, so not that different.
However, the old slug V8 is completely different animal to an isuzu so I don't know it would fare. I do know that my old auto scout was much easier to drive around town.

Yeah it would "work", but there must be something better that's turned up in the last 30 years.
