I have a 1998 jeep grand cherokee larado 4.0 with auto trans. I code a p0711 and a p0713. It goes in and out of overdrive after an hour or so of driving. Some days it doesn't do it at all. I had senso

    Had the sensor for the p0711 changed. Worked fine for a week and it popped up again with the p0713. Before all this, all I had was a p0711 and no overdrive. Light stayed on all the time.

Codes po711 andp0713 refer to transmission fluid temperature (TFT) sensor ---range /performance problem and high input===causes --wiring--TFT sensor ---ECM/TCM and wiring short to positive --TFT sensor ECM/TCM

Replace the TFT and have a check done on the TCM as it is what decides the OD selection process. Check the condition of the oil and oil level and change if not bright cherry red

Testimonial: "Originally the overdrive light stayed on. I took it to the shop and it coded p0711. They replaced the sensor and it worked fine for a week. Now I pop two codes p0711 & p0713 with o/d slipping in and out after an hour or so of driving with o/d light doing the same. All fluid has been changed. Jeep runs great and all gears shift great."

    Then the other unit in the equation is the TCM so have it looked at or changed

    Thanks... You don't think the trans is over heating? I need to drive it till I get it checked out. Just want to make sure it's safe to drive without ruining the trans.

  • Bill Boyd Mar 29, 2014

    you say that you need to drive it until you get it checked out . I have to ask when is that going to be ? 5 miles or 50 miles or 6 months . IT may not affect the transmission but then again who knows . The cost will be yours

    Within a week... So you really think it could be the TCM? I can change that out myself. I do live in a southern state that gets really hot in the summer. I can see heat over the years effecting that.

  • Bill Boyd Mar 29, 2014

    atmospheric temperature has little bearing on the operation of a transmission. What affects the operation is internal heat generated by faulty equipment. If the bands and clutch packs are out of adjustment then that causes slipping and the temp will rise .If the oil is contaminated then that cause the valves to not move correctly and so there is low pressure in system and that causes slipping and heat. Heat affects the electronics and the insulation of the electronic parts and so there are problems with items like the TCM. So besides changing the TCM check the clutch pack and band adjustment and the condition of the oil.

Your transmission fluid contain water,thats why the colour of the fluid changed to pink.And of such the clutch is slipping causing the engine to reve up before shifting - Check transmission cooler.

SOURCE: How to shift a 1998 jeep grand cherokee into 4 wheel drive

Four low is almost never used. I use it on very steep rocky or muddy trails in the woods or to pull someone out of mud or a ditch. Though some will shift standing still it is best do do this while rolling. Four high can be shifted at low speeds of 2 to about 35mph (higher also but not really good idea) Low can only be shifted between 2 to 10mph. If you find yourself stuck and unable to shift because you aren't rolling you can also turn the engine off, engage the transfer case and re-start. That avoids having the gears clashing together. Best rule is if it begins to grind, don't force it.

Aside from getting into an accident and having your wiring harness severely damaged, the other likely suspect is your PCM. These codes are not related to each other and indicate a much larger problem.
