Hey Marc -
I have  read the info in Pappy's links and printed it up, didn't see anything about having to drop the tranny though...   OMG/Shocked  We have a lot more room to work now than we used to -- poured some concrete on the camper side of the patio. 
I'll  let you know how it goes...  shy smile

Alright, I've been thinking a lot about TCC's in the last couple of days (thanks Isfinn1)!  confused?

Time to revisit the "dumb" questions (I'm really good at dumb questions).

Anyway, have you checked the adjustment on the TCC control cable? Might be a good time to clean it up, put some fresh lube on it, and especially clean and check the TCC ratchet adjuster and recalibrate it before you dig into a big project.

    Yesterday, I did successfully change the filter and gasket, but have not yet started on the TCC (other than cleaning some of the gunk off from around that side).

    Well, I looked at the FSM to reference Marcs suggestion and, well... it's way over my head, lots of greek.   confused?

    Quick question (might be dumb, but please forgive me)   shy-- I drove it onto ramps for the filter / gasket change.  For the next phase I need to remove the wheel, but my jack isn't tall enough to get above the ramps (at least  not without putting the jack on blocks and not sure how comfortable I am with that).   rolleyes
    So my plan now is to roll her off the ramps and then jack her up... But, I haven't added new fluid yet (since the TCC is next) ---is it OK to roll the car at this point; with very little if any transmission fluid? Or should I just suck it up and put the jack on blocks to raise the car above the ramps, so I can remove the wheel? 

    I'm probably making it more complicated that necessary, but want to be careful....
    Thanks, as always.   I really appreciate your help (and your patience).  Plus, I want to get this done so I can drive to the meeting Thursday ^^0^^

    When you say "roll the car" do you mean under power? You shouldn't operate the tranny with little or no fluid.

    If you just want to "roll" it back and forth by hand, no problem.

      Thanks Marc,  Yes, thought I would just put it in neutral and roll it off the ramps.  Problem is, I seem to be getting weaker with advancing age and so far, I can't seem to push it over the lip on the ramp -- really embarrassing and frustrating.  shy rolleyes   Tom is currently in SFL, he offered to help me move it before he left, but we just never got to it.

      I may end up adding transmission fluid so I can drive it to the meeting, but then I'll have to drain it again  rolleyes
      Oh well, things happen for a reason -- or at least I hope so.. ^^0^^

      Actually adding the fluid and giving it a drive is not a bad idea.

      I didn't want to criticize your efforts after you'd done so much work, but I would have checked the TCC cable first - adjust - then give it a drive to see what happens.

      If it's still not working properly then you could go ahead and drain the fluid and do all the work.

      This way you'll know where you're at. A better move.

        Thanks Marc,
        I'll do that.   Your input (and that of anyone in the club) is  certainly not viewed as criticism, after all -- you have experience and know what your doing.   I, on the other hand, I'm trying to learn and deeply indebted to everyone's help in keeping the BatMobile running.    shy  Wishing there were some Jeep folks out there like ya'll. sad
        So how do I go about checking / adjusting the TCC cable?  :confused: confused?

        Isfinn1:

        Here's the procedure from the 88 Service Manual:








        It's cryptic to say the least.

        I'd try a look-up on Pennock's for "Kick Down Cable adjustment". (Someplace I have a copy but no time to find it today)!  sad

        What the cable does in fact is it over rides the TCC solenoid to prevent it from locking up.

        As an example, if you were driving towards a traffic light intersection and the light suddenly changed yellow, if you "kicked down" the accelerator (mashed the gas), the transmission would down shift to accelerate and this cable would tell the transmission not to "clutch lock" while you were accelerating.

        When the TCC solenoid malfunctions (a typical problem with our cars and this transmission) the opposite effect happens: the clutch lock functions normally (like a 4th gear) but then doesn't unlock when you slow down. The result is the engine stalls when you come to a stop as the transmission is "locked" in gear.

        What I'm curious about with your car is the TCC is not locking up (shifting like a 4th gear) which is the opposite of the normal failure. Now it could be the TCC solenoid is indeed bad. It could also be a bad electrical connection or a poorly adjusted or non functioning TV/TCC cable.

        If you look down on the top of the transmission on the driver's side, you should see an electrical connection going into the transmission. This is the electrics for the TCC solenoid. Right next to that should be a cable going into a boot/plug in the transmission, which is the TV/TCC cable. The other end of the that cable is attached to the throttle body along with the accelerator cable and the cruise control cable.

        The trick is figuring out which item is causing the problem?  biggrin

        If the cable is not adjusted properly it can prevent "lock-up" when you want it to, which is what your car is doing. Just sayin. Hard to diagnose blind from 40 miles away!  OMG/Shocked But I do my best?  smile

          Thanks Marc, Yeah, I reference that manual a lot and generally like it better than Haynes or Chiltons, but this time it just reminds me that I'm really clueless.  So when you say TCC cable, that's the TV cable?  confused?
          I've been researching online -- Pennocks, Ogre etc.  and found several write-ups on adjusting this, but I need visuals.  ^^0^^
          Added fluid this morning and pulled her off the ramps, but still need to let her run and make sure the level is correct.  I plan to take her for a short spin to the post office after lunch and will dive into more research on the TV etc when I get back.  Thanks again... smile shy
