Well, it could have been just a temporary thing, but with the lack of a transmission fluid dipstick, I would go to a dealer and have them check the fluid level. Generally a transmission overheat should only occur when towing or otherwise straining the trans, or if the fluid is low. Since it did overheat, you may want to change the fluid too.

 

104* F, 85 MPH, that's pushin' it. Surprised it was the tranny overheating, not the Engine. If you meant 85 KPH, that's not so bad.

 

Wow! 85MPH??? I am surprised that you could take any corner in the Jeep at that speed. That would be like going 140KPH here and I would not feel safe going that speed in this vehicle. My old 2003 Crown Vic perhaps but not the Jeep.

 

o hai guise, i was out of town and w/o my pat, so usless to post





yup, 85 mph/140kmph, used to speed at 100 with my old car, and actually you can take a not too sharp (60°) corner at about 120km/h with out problem, and since the suspension is harder and my pat is not lifted i have good stability (once drove a ford bronco and the damn thing is "sofa king" unstable).

no, i mean 85mph/140kmh, and 40°c outside temp, A/C on, and high humidity, crossing a highway in a former swamp zone, flat as hell.

update of the situation: CVT fluid changed, CVT status: dark almost black (i've heard is light green the cvt), used oil smell (not burnt).

anyone knows the amount of fluid that goes in the cvt?



picture of the road, late noon, problem was about 2 hours before, cool landscapes.

 

You guys have a lot of corners in your highways over there?

140km/h can be a safe speed for a Patriot - on a wide open highway, traveling in a straight line, with plenty of visibility, little traffic and low to no winds. (Once the wind starts to blow, especially from the side, I would slow down quite a bit. I am assuming I don't even have to mention all the other factors that might affect the safe top speed...)

 

85 MPH on a interstate highway is no problem, I've done it for an hour or so, with no problems.

I agree with Todde, have it checked out.

 

I have done 85 also through alligator alley in FLA. Normally I just set the cruise control to 5 MPH over whatever the speed limit is so I don't get a ticket.

 

My trans light went on and the trans started to slip so I pulled over and let it cool for a while. When it cooled down the light went off . About 100 miles more and it went on again.
I did the same as the first time and then when I took it to a dealer the next day they said the code showed as a bad Brake switch!!!. Well within 7 or 8 days it started again, this time about every 50 miles. When I got it to a different dealer, they said it was the actuator. They got me for the deductible both times and nothing about the trans at all.
I have 75,000 on it now.

 

overheating!

I have a 2009 Patriot (jeep green) & it is a fleet vehicle for my job as an outside sales rep. It gets VERY hot where I work & I am in & out of the car all day. I can consistently hear my transmission struggling on a hill or the freeway and it has locked the car to 30-40 mph 3 times in a week. I pulled over and let it cool off foe a half hour each time so i could drive it. I had the same problem last summer & the dealer in palm desert, CA said they reset the indicator light so it wouldn't respond this way, it still does. Can this car not handle desert heat? It is at the dealer now & they are baffled....any help would be greatly appreciated.

 

I haven't had any issues with mine Elleb15. It's not a fleet vehicle, but I drive it around in the city and onto construction sites all the time in this summer heat. I haven't ever heard a whimper of complaint from the tranny.

Now technically my CVT2L is different than the CVT2, but I wouldn't think their cooling systems or capability were any different.

 

I find it to risky in pushing it that far... that would be the consequences you did.

 

No answer on my trans from the dealer, I've talked to the factory people and no help.
It does not feel the same when I drive it. Shifts different now (higher RPM's) but the dealers say the computer shows nothing.Not Happy. Just have to wait for it to blow up!

 

I wonder if the problem is a stuck closed secondary thermostat? The Patriot has two, a 180 deg. F Primary, and a 203 deg. Secondary that is supposed to increase water circulation and cooling. This may explain why some folks are seeing a CVT heat problem while the majority are not. I would also think there should be a way to put on an auxiliary trans cooler to help lower trans fluid temp.

We're seeing a 100 deg. F heat wave here in the Philly area, and I'm not having any trans temp issues myself, even running the AC on full blast!

 

Thermostat problems is the biggest issue with my car right now, if i was to get the thermostat replaced what can I do to prevent having this problem in the future? I do not understand why it is heating up, am I doing something wrong?

 

Finally found the problem, there is a problem with pin connector at the TCM.
After driving my jeep for about 40 miles today the light went on again. This time I was close to the dealer that fixed it the last time ( or they said they did) and I drove it there with the light on and the trans slipping for about 5 miles. Drove right into the write up area and showed the write up guy the problm without shutting off the jeep.
He then had the shop foreman look at it and take it for a short drive. The light went off while the trans was in park for 10 minutes. He was able to use his monitor and it showed a P0218 code. High Temperature Operation Activated. P0713 Trans Temp Sensor Voltage Too High.

 

What all did the dealership have to do? i am having the exact issue, its EXTREMELY irritating. is it something i can fix myself?

 

QUICK QUESTION...

My Patriot does not have the Transmission Temp. Overheat warning light...

Do only certain Patriots have this?

 

Yeah. The ones with Automatic Transmission.

 

i have an 08 automatic transmission, 4x4, 2.4L, anyone know the part number for the thermostat or what exactly the name of the part is so i can find it and replace it.

 

I live in Tucson, and if I am not careful, on the drive to Phoenix, I get a loud whine that coincides with higher rpms - I can' t go over 75 in the summer, or 2500 rpms, or the whine gets louder and eventually the light will come on (CVT overheat) - that car actually slowed on its own and I pulled over to let it cool, then continued - they checked the fluid at the dealer and said it was OK (I have 55,000 miles on my 2008 Patriot 2wd)

 

You must also replace the CVT cooling system filter in addition to the fluid and trans. filter. If it hasn't been replaced it will restrict flow to the cooler and cause overheating issues and eventual failure.

Go to page 48 of the link for location of CVT cooling system filter:

Hello guys i'm new at the forum, i was lurking the forums as a guest ,but now i have a question about my Cherokee 4wd 2.8 CRD diesil, 2005 , with 78k miles on it.

I live in Spain and would not be without my Cherokee Jeep, I have done a couple of trips on the motorway in the last few months, with my well maintained jeep , and i was pushing the pedal at about 85 mph/140Kph hr, watching over the temp gauges and instrument panel, and then I saw the temp gauge start moving towards the overheat end of the scale. I pulled over into the slower lane, and dropped my speed to 75mph /120Kph and the gauge returned to normal working temp over next 5 min. Have tried with cruise and without cruise on, no different, surely this 2.8 jeep can go more than 75mph/120 Kph without overheating ? Is this normal with Jeep ?
any help you guys can give is appreciated .

 

Same thing at the dealer in Tampa Fl. They don't why the light is coming on. Anytime i drive long distance for more than an hour the light comes on and I have to pull over to let cool down. It sucks and nerve racking. (2010 Jeep Patriot).
