ECU?

[Bart F-350]

At the left foot of the driver, behind the cover and hood-opener sits a metal "computer" box, if your truck, like mine 1989F350 7,3 IDI, is equipped with the E4OD auto trans.
is that thing called the "ECU"?
and can I just like that order a "remanufactured" one, or is it more complicated?

It would be the "TCU". It doesn't control the engine, it controls the transmission.

It is the same as the EECIV ECU's, though it is a special one that just controls the transmission. But it has the same hook-ups for the code reader that the fuel injected gasoline cars and trucks use.

Ok, that was what I thought.
I thought to link it in here, but just now I see that those things are only for gas engines (at least those who are displayed.)
Are they still for sale for diesels as well?
Or do I need searching for something else? more trans oriented?
(if I can't get rid of the corrosion on the contacts?)

TCM or Transmission Control Module. It has no function for the engine just the tranny.

You can get re manufactured from the big parts stores.
