good point about not saving money.
Assume the overdrive swap cost $1500, you get 12 mpg now, and with the overdrive you get 16, and fuel cost $3 a gallon.
It's late, and my brain is not working quite right. But I figure it takes 60,000 miles of driving with the OD installed to pay for the fuel savings. Someone check me on this please.
I just assumed you had a manual, as all real trucks have manual transmissions. If you did then I think that the Ranger OD is probably the best buy. You could switch to a manual?
If you did go with a manual you have overdrive transmission choices, like the expensive NV4500. Or with some work, and a flywheel, clutch and bellhousing from a big truck like a dump truck you could install a surplus cheap spicer 5 speed model 3053a from a deuce and a half with about .84 OD.
Or as mentioned before an automatic with an OD, but I know next to nothing about automatics. I do know that all un-computerized Allison's are direct drive. It was not until they were computer controlled that they were offered with OD, and the newest ones in a Chevy truck have two overdrive gears, high is about .64.
