There are others but I have used these with good results.

I'll have to look around but there is another company that makes them,
maybe
TCI. The good and bad. You can use a OEM controller and harness but in
order
to tune it you will have to look into something like tunercat. Also you
need
to look at how to handle your tps and map. The diesel shift points are
gonna
suck if you cant change them. I don't know the exact RPM but the diesel
controller is gonna spit out some low RPM shifts. There is actually not
cheap and easy way to do it. If you use OEM you are gonna save maybe
200/300
bucks but you are gonna be dealing with a wiring nightmare. Spend a few
more
bucks and you have plug and play. How valuable is your time?
