Look down the radiator and see if there are a couple of extra pipes.
At least on the ZJ, these are on the driver side and are part of an
in-radiator transmission cooler. The aux cooler splices into these
lines.

This doesn't apply to this case but I found it interesting and somewhat hard
to believe.
Excerpt from '02 WJ FSM Section 7 Page 55:
TRANS COOLER
DESCRIPTION
An internal high capacity/high efficiency cooler is
used on all vehicles these coolers are an oil-to-coolant
type which consists of plates mounted in the radiator
outlet tank (Fig. 36). Because the internal oil cooler
is so efficient, no auxiliary oil cooler is offered The
cooler is not serviceable separately from the radiator.

Re: 1998 Jeep Cherokee Sport Question #1-Towing-Transmission Cooler perowner's manual
Hi Earle,
Remember the air cooler is as much for the engine as the trans.
Going back to the cars of the sixties they were right on the ragged edge
of engine over heat anyway, and additional hot transmission oil was the
last straw. The element went in before the radiator, to make sure the
transmission's oil was always at operating temperature.
