92 explorer al4d into 89 Bronco 2

[Bent Bolt]

a 1992 A4LD will fit and function PERFECTLY in an '89 Bronco2 with a 2.9.

But there a few subtle differences beyond the general fact that the
4.0 A4LD is "beefed up" compared to the earlier A4LD's

the 4.0 torque converter has more vanes on the stator inside it so it is
a much "tighter" torque converter.

This means you'll notice that the converter doesn't slip nearly as much
as the 2.9 converter will, and this will slightly affect low end acceleration
(just away from a standing start)

It also means that when the computer ALLOWS the converter to slip on acceleration
(when it releases the lockup clutch) it'll generate FAR less heat.

Some people simply don't notice the difference, most do.

So true.

Canoeman,
the 92 A4LD will bolt in and function perfectly well with the 2.9 converter installed. Stall speeds are different, the 2.9 engine will act like a dog with the 4.0 converter.
Only hick up might be the shifter lever attachment but that will be fairly obvious.

so use the 2.9 converter instead of 4l converter? should I purchase a new one then.

Yup.

I'd recommend a new one. They're fairly cheap now.

$175 for a new converter. Tranny shop says they dont interchange. But from here I understand I can use my 2.9 l converter into the tranny from the explorer which is a 4.0 l.
And that is the way to go. I also understand it is plug and play from there.

Technically , they're right --- because the stall speeds are different --- but I know for a fact that they will physicaly will swap. It's been done many times.
