Ford Transmission :: Temp Gauge Reads High Even When Truck Is Cold

I have a 2002 F-350 6.8L, 4x4, crew cab, 8' bed, SRW, trailer tow pkg. I purchased it new in the fall of 2001. The truck currently has 54,000 miles on it (only gets used when I need to tow/haul something). It's kept in the garage and is in near showroom condition.

Everything on the vehicle is 100% functional except the transmission temperature gauge. Even when the truck sits for weeks, the needle will move to mid scale as soon as the key is switched on - haven't even started the engine yet! Put the scanner on it - no codes stored.

I'm attempting to trouble-shoot the TFT (transmission fluid temperature) sensor. Found some documentation online on the 4R100 transmission. It shows an electrical connector on the solenoid body with pins for the thermistor (so I can measure its resistance). However, I can't find a connector anywhere on my transmission that even remotely resembles the diagram I found online.

Question 1: When you first get in your vehicle and turn the key, does your tranny temp gauge read "cold" just like the engine temp gauge?
Question2: Does my truck have the 4R100 transmission? How can I verify that?
Question3: Looking for documentation on what connector and which pins are for the thermistor?

Ford A/C :: Temp Gauge Reads Cold And Does Not Budge Whenever Truck Is Running

I am trouble shooting my temp gauge. I have a 1997 f350. I brought the truck a year ago and i have still not fix this problem. I install a new temp gauge and nothing changed. When ever the truck is running it reads cold and doesn't budge. Ive read that the gauge can be broken its self but during a few hot times over the summer. The gauge began to rise slower, never reaching normal temperature. A few times i messed with the heat and the gauge would shoot over the normal temp. The truck seems to run at a good temp sometimes hot though. The tube on top of the radiator is hotter than the bottom also.

Passat (B5) :: Engine Code 1106 / Temp Gauge No Longer Reads Anything

Mine is a 99 gls with the v6 and manual trans. I have 108,000 miles on it and mostly performs great except that my cabin lights are dead (moon roof still works, dash lights even the lights in the doors for the windows and locks light up but not the cabin lights and I can't find a dead fuse anywhere and the dealer looked at it for an hour with no luck). [URL]...

Mine is pretty intermittent at least over the last 6 months, but my temp gauge no longer reads anything and I've gotten a CEL twice now, this second time I pulled the code at autozone with an answer of 1106. I've had my 90k maintenance with the timing belt/water pump/coolant flush service.

I've also noticed when starting it up in the morning I'm getting quite a varnish smell out of it that my wife's 07 Rabbit doesn't produce and my mileage is still around 25 mpg for a 5 mile commute.

Now I see this is a pretty cheap part, so I'm going to wrench it myself but... where the heck is it? I've done the electrical replacement on my 96 jetta wolfsburg that had the 2.0 in it which was pretty easy but my passat seems to be hiding everything under the hood with fancy engine covers and stuff.

Chevrolet - S-10 :: 1969 - Temp Gauge Reads Hot All The Time After Grounded The Sender Wire To Engine?

I have a 1969 chevy c10 pickup. One of its problems is the temperature gauge was not reading. I grounded the sender wire to the engine block to deterimine if the sender was bad, and ever since the gauge reads hot all the time, even with the ignition off. Could I have fried the gauge?

Ford - Explorer :: 1998 - Temp Gauge Shooting To High In Just Seconds Then Drops Back To Normal

For reasons I can't figure, the Temp gauge on the wife's Explorer is shooting from normal to high in just seconds. Then, it drops back to normal. When I looked at it this afternoon, I noted 2 things.

1) There was no sign of a coolant leak or overheating.

2) There wasn't ANY coolant in the tank!!!!!!!

The truck has evidently been running fine while this is going on.

Ford F-150 (2004-2008) :: Temp Gauge Reads Normal / No Pressure In System

My friend has an 08 4.6. He has replaced the thermostat with 3 different ones all with different temps, still nothing. Temp gauge reads normal but after driving it for a bit he can take off the radiator cap while it's running and not get sprayed in the face with coolant, almost like there is no pressure in the system.

Volvo :: 1988 240dl - Temp Gauge Reading High But Engine Is Not Actually Hot

I was recently given my first Volvo. Its an 88 240dl. While driving my temp gauge climbs up to the red and sometimes hovers inside of it. It normally climbs up at stop signs and comes down on straight always then climbs right back up close to red. When the gauge was in the red i stopped the car and popped the hood open to see that the engine was not actually overly hot.

first i replaced coolant. nothing
then i replaced the thermostat. nothing
flushed radiator. nothing

Today i finally had enough and decided to switch out the water pump with a new one hoping that it would solve the problem seeing as it still had the factory one on. It did nothing. the gauge continues to climb up. I did replace one of the two senders in hope that it would fix the gauge reading but nothing.

Ford - Explorer :: 2002 - Temperature Gauge Not Working After Replacing Engine Coolant Temp Sensor

2002 ford sport trac.I have been having an ongoing issue that started with the engine cranking but would not turn over until an hour passed. After replacing multiple parts (cam shaft sensor, crankshaft sensor, ignition pack) I am now down to poor fuel economy as the last of the issues (roughly 12 in the city and 15 highway). I was told the issue may be the engine coolant temperature sensor going bad so I decided to replace it. I found this was very difficult due to it being a plug and locking pin design and in a very tight spot in the engine.

I tried to purchase a replacement and the parts store kept trying to insist on selling me a part with threading. I finally found someone that figured out the issue and found the part for the 2001 sport trac had the same plug style with clip that did fit but was shaped a little different on the sensor end which I assume was due to being aftermarket. I noticed that there were two plugs side by side and the one easiest to access was on the left and I was told the one on the right was the sensor that gave the temperature reading to the gauge.

After installing the engine coolant temperature sensor I found the temperature gauge on the dash now will not respond and is sitting below the cold end of the gauge completely off. Is it possible this is because the part was for a 2001? Is the sensor on the left (passenger side) the engine coolant sensor?I would hate to put the old sensor back in just to test if that's the issue due how difficult it was to put that locking pin back on. What to check that could resolve the gauge issue before pulling this sensor back out?

Ford Transmission :: 2002 - Temp Gauge Move To Running Temp In Cold?

02 6.8 4x4 excursion. When I start the truck cold, the trans temp gauge immediately moves to "running" temp. Not really sure how this happens, I'd figure that if the xducer was trash it would ride all the way high or all the way low. What's happening here? I'd sure like a functional gauge...

Malibu :: 2003 Engine Temperature Gauge Always Reads Above The Half Point

I have a 2003 Malibu with 29,000 miles on it. I notice my temperature gauge reads a bit over the half way mark when driving around town. I don't notice any type of coolant leak. The gauge almost always reads above the half point, but never gets to the point of overheating. Sometimes it comes close to it but never actually overheats.

Explorer :: 2007 - Overheating As Temp Gauge Reaches To Max?

2.5 months ago I had a coolant flush in my 2007 explorer Eddie Bauer. The last 3 days last week the temp gauge went from the middle where it usually sits, to maxed out in the red. Stays there for about 45 secs and then drops back down.

Is it coincidence that I had a flush and maybe they didn't fill it all the way back up or is it somthing else ?

One other thing- even when it sits in the middle of the gauge I can sometimes hear the engine sucking in air like a vacuum so I guess at certain times its running hot but just doesn't raise the gauge just yet.

Subaru :: Temp Gauge Stuck On High

We have replaced the sensor twice now and it still pegs on high. Sometimes when we just start up the car, other times after we are driving.

Elantra XD (2001-06) :: Fuel And Temp Gauge Would Either Be High Then Go Low

I replaced my battery. Once I connected my new battery, my fuel and temperature gauge started working strangely. They would either be high, then go low, then go back high. My interior lights, clock, and radio stopped working. Could it be a relay? I checked all the fuses with a test light and they all looked good.

Suburban :: 1995 - Temp Gauge Going High And Dropping

Bad news kids... it's terminal. Took my 95 3/4 ton 4X4 6.5 diesel suburban in complaining of temp gauge going high and dropping, alternator... ball joint fears.... And I just got a call, it's got a cracked head. So this is how it ends. Husband aint never gonna fix it. I knew this day was coming. He said the temp gauge going high then dropping is some sort of coolant preasure build up and release. I seen it every morning for the last year. He said he took her up to 120 kms and it did exactly what I said. And he knows exactly what my problem is. It's true, Toni knows this truck. So any guesses how long I got? What will happen when it goes? When would you park it for good? My last over heat was a couple years ago when a belt blew off, big heat is the only thing that would have cracked a head right? So the crack might be that old. And it's sad news. Driving it since birth, 95.

Explorer :: 98 Ford Temp Gauge Stuck In The Middle Whether Car Is Off / Idling Or Driving

I have a 98 Ford Explorer 4.0 v6 My temperature gauge is stuck in the middle whether the car is off/idling/driving. I am wondering whether this could possibly be an issue with my coolant temp sensor/sender, or wiring.. Or since its just stuck there, would it be the gears of the actual gauge..

Chevrolet - Montecarlo :: 2002 - Temp Gauge Bouncing From High In The Red To Low

I have a 2002 Monte Carlo what recently had a new radiator, thermostat, intake manifold gaskets replaced. I was spewing coolant everywhere. Since the repairs with all new OEM parts, I still get the 'Hot Coolant Temp" warning on my dash. The temp gauge is pinned at 260 but minutes later drastically drop to under half way after which it seems to balance out at slightly under half way.

I also see the 'Low Coolant" as well even though I am full. All of this occurring while driving. I checked the oil and underneath the oil cap. No frothy or milkiness. Exhaust seems ok, no white smoke. The heat inside my car when i run it seems to go from warm to cold and back again. I'm praying it's not a cracked heard or blown head gaskets.

Subaru - Legacy :: Temp Gauge Went Up High / Reservoir Was Empty

A few days ago, the temp gauge in my 1995 Subaru Legacy went sky high in a matter of 2 minutes. I immediately stopped the car, let it cool down & checked the radiator. The reservoir was empty and radiator took about 1/2 gal of water (I figured water was fine since the weather is 90 degrees here right now). Suspecting a leak, I also added a bottle of that "Bar's Stop Leaks" stuff. I hesitantly started making my way home, about 16 miles away. The car was perfectly fine -- no overheating at all. Next day, I drove the car maybe 10 miles & again no problems. Yesterday, I went to a friend's house -- about 50 miles round trip. I assumed (I know, dangerous) that all was well ... until today. This morning I noticed a small puddle of antifreeze near driver's front tire. The reservoir was down by about 1/2 it's capacity BUT the radiator itself was almost full (if it took 3 oz. that was a lot). Now I figure there's a leak, but if there is then why wouldn't the system drain itself all the way? Is it unusual to have a leak that limits drainage?I am also tempted to add another bottle of stop leak but looking around this ...

Ford :: Temp Gauge Goes All The Way To Cold When Stopping Or Slowing Down

I recently replaced my alternator. I thought I was very careful not to make anything worse but now when I'm driving I have temperature issues. When stopping or slowing down my temp. gauge goes all the way to cold, then as I accelerate the temp gauge rises to the middle. It has not gone past the middle and has never done this before the repair. Also, the truck has never overheated or had any thermostat or cooling issues before.
