Auto Trans Question

99 TJ Auto Sahara 127K miles
Process of elimination from Jeep not starting:
Replaced battery to Diehard
Replaced TPS
Cleaned air intake
Cleaned idle air valve
Cleaned and reset ECU
Jeep started, but I broke the plastic end on detent cable. Replaced today.
Now shifting at 15mph/1250 Rpms is hard. Was not a problem prior.
Trans fluid is good. Any ideas/direction to go from here?

And the last time all of the transmission fluid was changed?

Which transmission cable did you mess with? The kickdown cable that attaches to the throttle linkage will screw up the shifting if it's length adjustment is off even a little. It needs to be adjusted so it is just taut without any pull or slack when the throttle linkage is at rest.

I've owned the Jeep for almost a year. It is a toy/hobby that I don't get enough time to enjoy. It's only been driven approx. 5K miles in the last year. The fluid was changed approx 15 months ago and I verified the service. The cable that is closet to the radiator was the one changed with Same routing as the one previous.
Thanks for responding!

Closest to the radiator? Are you talking about the control cable that connects between the transmission and throttle body? If you replaced that one, its length has to be adjusted as I described above.

The dealer called it a detent cable, but yes it's closet to the radiator and the center one is the cruise control. There is a very small amount of adjustment that could be done, but how? This end has the metal stop on it and the other end was plastic that snapped on near the Trans.
Sorry for my ignorance, but want to do as much as I can myself.

The cable length is adjusted by releasing its plastic clip next to where it passes through the throttle body bracket that holds it. Once the clip is unlatched by unsnapping it and lifting it up a 3/8" or so, the cable sheath can be moved in or out until the inner cable is the right tightness... not pulling on the lever it is attached to but zero slack in it too. Just taut without any actual pull on the lever.

So the problem was fixed by adjusting the cable length?
