'til it dies.

No, just kidding.

But seriously, they can run a very very long time if maintained properly. They're very sturdy. The variables are driving habits and fluid changes over the course of its lifetime.

The transmission is manufactured by Aisin-Warner, a member of the Toyota group. A very good reputation for reliability.

(from Wikipedia)
Models that used the AW4:
1987–2001 Jeep Cherokee (XJ) 4.0 L
1993–1993.5 Jeep Grand Cherokee (ZJ) 4.0 L
1987–1990 Jeep Comanche 2.5 L
1987–1992 Jeep Comanche 4.0 L

It also turns into a huge Foreman Grill when not maintained well and wheeled heavily with 4.56's in 1st gear.

I like my automatics like I like my steaks.
