32RH (has bands) page 96 and 97 (band adj)
or
AW-4 no bands. uses solenoid clutch packs. electric.
see them both and all tests and settings.
is yours a TCM shifted ? tranny, yes then why not scan it.
or the flash code procedure. page 174


the TCM cars will flash OD lamp or drive lamps or something
to tell you its got error codes.
get them.

best of best. aw-4
(see the manual mode test. many cars have this, not just jeeps)
may TCM tranny cars, (RTM read the FSM and learn this)

hint 2:
make sure the tranny ground stap is not broken.
if it is, it will never ever shift right or reliably
true for just about any TCM car.
see one guy last week bought new tranny ,and never used
a voltmeter on the solinoids. had 12v casing.. a shame.
