Where is the transmission control module located on a 1999 jeep Cherokee 4.0L exlcudes grand Cherokee?The Trans Control module is located behind the plastic covering of the center console. It is on the drivers side, next to the gas petal. Where are the oxygen sensors located in a 2000 jeep Cherokee sport 4.0 L?They are screwed into the exhaust pipes on either side of the catalytic converter.
Where is the fuse located for the cruise control on a 99 jeep grand Cherokee limited?haven't got a answer yet Where is cruise control fuse on 1998 Jeep Grand Cherokee Laredo 5.2?I have a 1998 Jeep Grand Cherokee Laredo 4x4 with the 5.2 v8. The cruise control fuse for mine was located in the steering column. Its an in-line fuse. Where is the security system located on a 1996 Jeep Grand Cherokee?where is the security system located on a 1996 jeep grand Cherokee I couldn't find my complete TCM test procedures but the following will alow you to test the solenoids. Before beginning verify your transmission fluid is full. Examine the transmission connectors at the trans dipstick for cleanliness, security, and chafed wires, especially the "TCA" connector. (refer to pic below).
 To access the TCM, remove the trim panel and knee blocker below the steering column. TCM Location:
Before removing the TCM connector disconnect and isolate the battery negative post connector. Study the TCM pinout below to get familiar with the connector pin cavity configurations.
These are tests you can perform at the TCM connector to see if a solenoid is bad. You'll need a digital Ohmmeter. Refer to the TCM pinout below. Test the Solenoids: Ignition OFF/LOCK, disconnect battery negative post connector. Verify the TCM ground connection has full continuity. Using the Ohmmeter, read between pin cavity 24 and a bare metal spot on the dash. You should see near full continuity. If there is resistance, you�ll need to clean the wire ring terminal connections at G101 on the engine block. Read between pin cav 12, 1-2 and 3-4 solenoid (A), and pin cav 24 as ground. You should see between 11 and 15 Ohms. Repeat tests at pin cav 13, 2-3 solenoid (B), and pin cav 11, Lock-Up solenoid (C). Again, you should see between 11 and 15 Ohms. If any one of these tests shows a solenoid with out of range resistance, suspect the respective solenoid is bad. Note that pin cav 24 is the TCM ground at ground G101 on the engine. It's located at the ignition coil attach bracket
studs. Below is a visual on the solenoid location in the transmission:

Feb 27, 2011 I have an 02 TJ and the TCCS appears to be bad. It only has 62000+- miles. It drives fine but I have noticed a drop in gas milage, to be expected. I took it to a local shop to be diagnosed and was told it was the mechanical portion of the TCCS itself, from what he could tell. So as we all do I started looking into if I can do it. After doing
what I could, as far as research, I can not even find a place (web site, books, ect) that can show me how to access it. So can anyone tell me? Is it in the tranny itself, on the outside or just flat out hidden. As you can tell I'm not a tranny guru. Should I even attempt this task or just man up and take it in. My next question is, is there a better one (performance) that I should replace this with. It is my daily driver but anything to better my jeep would be worth it to
me. Please help if you can :cheers2: Joined

The tcc solenoid is on the side of the valve body in the trans. What was the exact code pulled...not really a code in the system that will tell you there's a "mechanical" problem with the solenoid. There are a few other parameters that can prevent lock up. Joined

Feb 27, 2011 The code that shows is the PO740. The shop told me that they ran several different test and that would be there guess without dropping the tranny to look inside. I have tried several things that other people have mentioned; checked the wire connection at the tranny and even replaced the wire connection. Checked the tranny fluid level, was
told if it is over filled that could cause this code. About the time this happened I had replaced an aux tranny cooler, because of a leak. I have asked before if this could have anything to do with it and nobody seems to think so. What is your thought? If you have anyother thoughts please shoot them my way as I am open to anything at this point.

The solenoid itself is here, on the valve body inside the pan...

All that code tells you is that the clutch did not engage properly. there are codes specifically for the solenoid failing, that its not one of them. Check your brake switch and throttle position sensor. Verify fluid level as well.

What would the brake switch have to do with it? in some vehicles,when the pcm receives a signal from the brake switch(brakes applied)the pcm will disengage the torque converter clutch to prevent the engine from stalling. Joined Jun 25, 2010 · 9 Posts

I know this is an old thread but, would the brake switch keep the torque convertor from unlocking and or engaging too early? Joined Jun 16, 2005 · 35 Posts
Only 4 1/2 year old thread.... I'm having a problem with my '97 TJ 4-banger that seems related to the torque converter. Basically the clutch won't engage at stop, when the engine is warm (seems to work normally when run while the engine is cold). Of course this means every time I come to a stop light, the engine freaks out and stalls. I have
to throw it in neutral when coming to a stop. Sometimes when I put it back in drive to go, it stalls out again unless I give it a little gas at the same time. I know nothing about auto transmissions (except how to check the fluid). The fluid level is good and it's clean. The tranny was rebuilt about 18 months ago. I've looked at the brake switch. It seems fine (it's moving normally), but I have no idea how to remove it. It did throw a code a couple of months ago - P0740 or P0743 or
something like that. Checked fluid, cleared the code, and it has not come back. I took a look at the solenoid wires. They're attached, is all I can tell. It looks like they're just stuck in there - not sure how to pull or re-attach. Maybe I should check for signal on them, but I don't know what to look for ... Joined Apr 19, 2017 · 1 Posts
Hey, direwolf, how did you solve the problem? My step-daughter's '94 is having the same exact issue. Buddy of mine at the shop suspects the tcc solenoid but didn't want to pull it just yet. Joined Oct 24, 2017 · 3 Posts
0740 codes of SO my JKU 2011 has this code and the hot oil light came on so I had it towed home I can't find anything about the TCCS how to check or location any advise

You may have to pull the torque converter to check its operation. Hot oil usually means a frozen stator. The TCCS is in the valve body as shown above. Does a torque converter have a solenoid?The torque converter clutch solenoid is an electronic component that helps to measure the fluid pressure and regulate how much fluid the lockup clutch receives. If the solenoid is faulty, there won't be an accurate measure of how much transmission fluid is a need which could lead to abnormal fluid pressures.
Can you replace a torque converter clutch solenoid?Replacing A Torque Converter Clutch Solenoid
Whenever any of these fail, you will not be able to generate the necessary pressure in the torque converter to shift gears effectively. It is very common to replace all these parts when replacing a TCC solenoid. All of these parts can go out at the same time.
Where is the torque converter clutch solenoid located?A torque converter clutch solenoid controls the flow of fluid to the torque converter. It is located near the transmission and the engine's rear. An electromagnetic coil controls the solenoid. It moves a plunger inside the solenoid shaft when it is activated.
