95 grand 5.2 trans ?surging?

95 grand cherokee 8, 5.2L 4x4, new tune up, new fuel filter, regular injector clean additives, all new front end ties, breaks,
Auto trans oil and filter done about 1300 miles ago, adjust TV cable yesterday = that put an end to the random “clunking” during shift, and made the shifting way smooth.
.
Issue: at about 65+ mph under acceleration, feels like surging, as if gas is restricted, but RPMs stay steady, and acceleration from 0 or any other speed is strong. “Surging” like pumping the gas pedal, and steady rpms make me think transmission adjustment.

? Tighten bands
? Replace adjusting .. solenoid… ? Is there anything to replace during a filter change besides the filter and oil?

Everything I know about the automatic trans is; pull pan, make mess, change filter, add oil. Check oil level.

so I have been looking through the service manuel and answered part of my question, but I am not familiar with the automatic trans.
would it be just the band at 3rd/overdrive, or something else?

then I thought; some of these many sensors might be having some kind of effect on the shifting, Can a sensor cause 'pulsing' in the drivetrain?

"surging" what exactly do you mean by that?

rapid go/ release/ go/ release/ go/ feeling,

check the fluid level lately? yes, running in neutral is full.

what could it be? I don't know, thats why I am asking ......

I had the same issue shortly after installing new plugs, wires, cap and rotor.

Routing the wires described in the TSB below fixed it:

Check the tps sensor on throttle body . They can cause surging and shift issues.

No. I just thought I'd **** with ya.

Yes it fixed the random misfire CEL and surging at speeds above 45 MPH, which was most noticeable on the freeway for me.

that is the "TV cable", making that adjustment does help a wide range of issues.

Did you also check or change out the TPS? and or make sure the plug wires are not touching anywhere?

I have not checked my TPS yet, (working on a s-10 starter issue taking too much time)

THis issue only just began, aka; tune up and new cat/muffler and test drive = all acceleration was good, then a few days later it began the "surging" ....

I actually changed the TPS because it died on me but the plug wires are everywhere didn't think it would cause this problem.

changed out the TPS, made no change. accelerate from 0 to 60 is all good. cruising at 50 to 65 and then accelerate - automatic trans- feels like it is slipping and or jumping between gears... adjust a band?

or where to find details on how to analyze and adjust trans...
