Ford Super Duty (1999-2016) :: Transmission Overheating A Bit - Codes P0741 And P0743
May 31, 2015
For the last few weeks I have noticed my transmission overheating a bit, nothing bad, but I have just been running around town local so no drives over about 15-20 mins.
Well, Friday night I went out to see a friends band play about 40 mins away, My trans temp climbed steadily the whole way out there, peaking at 226 by the time I got out there. I kinda took my time getting home hopping bars to give the trans a break to cool off.
Did some diagnosis today, first thing I did was unhook the line going to the rear of the transmission and did the bucket flow test. I fired it up and fluid came pouring out of the line which goes into the rear of the trans, nothing really came out of the rear of the trans, it was all out of the line.
So that tells me that its getting flow through the coolers. I didn't measure the amount like some do, but I can tell you it looked like a strong steady flow.
I made sure the fluid levels are proper as well which they are, it was maybe a 1 quart low which shouldn't effect anything. I also inspected the coolers and everything appears to be clean with no airflow restrictions. Took it out for a brief drive again and it climbed up to 147, maybe 5 miles out 5 miles back. Ambient temp is 62 today.
I am getting multiple codes on my Edge Evo which I have had set to stock settings since I bought the truck. Codes I get that concern me relevant to the trans are P0741 and P0743. Both seem to relate to the torque converter.
I feel like my RPMs are a bit to high at highways speeds so I am wondering if I have a TC that is slipping a bit while driving. I did notice a bit of a metallic pearl in the fluid that came out. Aside from that I feel like the trans is shifting ok, though sometimes I have to let off the gas to get it to shift into 4th.

99 F350 7.3l with 4R100 trans. About a month ago I took out a monster trans that had about 60k on it and it was burnt up. No warranty. ..customer bought another monster. After the install when going into 4th the torque converter would instantly lock making it feel as though the truck was falling on its face. Monster had me do some data logging and from the info I provided they determined it had a bad solenoid pack. They sent a new one out...when I went to install the new pack I noticed when I dropped the pan that the fluid was iridescent looking...a bolt for the valve body was in the bottom of the pan and lots of material stuck to the magnets....
Needless to say that trans only lasted about 2 weeks after putting the solenoid pack in. Fast forward to today..got trans number 3 from monster under warranty. After the install everything seemed good. About 30 mins into highway driving the od light starts flashing. ..subsequently the P0741 code. I did put 2 new wire pigtails on the front and rear speed sensors. The pigtails were a ford service part but they were a bit different in design. I am pretty sure the wires are correctly oriented..if not would this cause the issue. I really am leaning towards a bad solenoid pack again. My buddy thinks the TC isn't seated properly....where do I start? Also has an edge programmer on it..but it's been on the same map all this time

My buddy has a 2002 F350 CC Longbed with a 7.3. Last night the overdrive light started blinking. He said he drove it today and it takes about a mile or so for the light to come on but then it is a steady blinking. Truck has about 254K miles on it. He said other than the blinking light everything seems normal. How to figure out what this issue may be?
I got AE hooked up on his rig.
When I pull (ALL) codes this is what I get:
When I pull (Current) codes I get this:
I tried to clear the code and the light stopped blinking, but he said it started blinking again on the way home.

My '01 7.3 is having some transmission problems, My O/D light is flashing. Trying to go after stopping at a light is a difficult, it drives very sluggish, like its not in overdrive. Scanned it and got three codes P0732, P0720, P0503. I replaced the ABS/VSS on the differential and the problem still exist.

Im running an 2008 F-450. And towing a goose neck trailer with the total weight of 12,000, including the car in tow. We were traveling from Cleveland to Columbus last week. Traveling south down Rt. 71. Which has some subtle gradient here and there. But nothing extreme. I haven't tried any mountain runs yet. when i started noticing the temp gauge climbing from middle normal range to high normal.
It would then kick out the cruise control. It would cool off after about 5 minutes of slower driving. We were only traveling at 65 mph. Outside temp was about 78 degrees. I shut off the A/C and it seemed to improve. Should it be over heating like this. The capacity of the 450 is 25,000. I am at half that right now. Are these truck prone to heating problems. And if so. Is there a high performance supplement cooling system.

Ok, so the OD light sometimes blinked and sometimes not. I drive for a week. About 500-600 mi. Today the tranny starts acting up. Up until today NO probs at all. I bought a code scanner. Codes are P0781, and P0743. I also bought new filter and fluid while there. I read here that it could be a shift spring that is easily accessed when doing the filter change. I guess I should get that and do it,and the filter and see what happens next?

My Son drives a 2012 6.7, and just recently it started overheating bu only under acceleration? It runs cool while idling, and once you reach the desired speed, it cools back down, but under acceleration it overheats? We've checked the obvious (coolant etc...), but can't figure out what it would do this only under acceleration?

I have a 2008 powerstroke. Dpf and egr have been fully deleted. SCT tuner seems great and have had no issues since installed 6 months ago. I recently hooked up to my camper and headed up a mountain pass. As soon as I started uphill the engine overheated. I allowed it to cool and tried again with the same result. Eventually had to unhook and have another 6.4 (this one being a 2010) pull the trailer the rest of the way. Haven't had any heating issues since unhooking.

I have an 11 F350 6.7. It has just under 200K miles on it. Yesterday I changed the oil. Very uneventful. Today however, I was driving home, about 100 miles, and my truck's temp spiked. Not like a little spike, but jumped to the 3/4 mark(if there was one) then slowly kept rising to to the overheat mark. I pulled off onto the hard shoulder waited an hour or so to let it cool down, then finished the drive home.
All the way home my temp gauge seemed like it was on some sort of drug. It would jump a needle width when I would have to accelerate, then slowly cool to normal after I got up to cruising speed.
When I got home I checked the oil level and it was spot on in the "normal" range. I haven't used a different type/brand/weight of oil in the last 100k miles. Did something just give out on my truck? I had the coolant flushed and replaced at the dealer within the last 10k miles.
Up until this point this truck has been exceedingly reliable. I pull a 13k 5th wheel once a month and drive about 40k-ish miles a year.

My 1999 f-250 superduty shows overheating after it runs for awhile but it doesn't actually overheat the gauge just shows it. What it does is drops down to four cylinders. Is my heads blown or could it be something else it has 260,000 on the engine.

I have a 2001 F250 with the 5.4l. I got home today and a lot of steam was coming from under the hood. I couldn't see where it was coming from. I see a reflection on top of the engine near the intake manifold. The truck is not overheating and the heater is working great. I changed the thermostat several months ago. What the issue may be. I checked the dip stick and not visible signs of water in the oil. What this could be? Is there something besides the visible thermostat housing that may have blown a gasket?

I have a 2000 f-350 that overheated 2 months ago I replaced the radiator...it seemed fine for a month then started blowing cold air then would start to overheat and back and forth so I replaced the thermosat.......but when i checked the old one with a cooking theromometer it was fine. not long after that the heater core started leaking so i replaced that..and now its back and forth overheating and blowing cold air....then fine for 1/2 hour..then back and forth again.. Truck has 250,000 miles on it

I have a 2001 excursion 7.3 4x4 with the 6.0L trans cooler. It is over heating when heavy, uphill towing is under way. I am guessing that my computer has been reprogramed at some point and more fuel is being injected than the radiator is designed to cool. I know my trans cooler is clean. I have tried cleaning the radiator and intercooler with a garden hose. I am considering a hood scoop or some sort of vents in the hood. When it over heats I turn on the heater and open the hood and the engine temps drop in just a few minutes so I believe that the engine needs more cooling or I need to slow down a bit on hills. Any other cheap fixes to get more air in to cool things under the hood more?

I have a 1999 f350 v10 stock truck. It has plenty of power when it's cold out or raining or I'm on backrooms or highways but if I drive through town on a hot day the transmission kicks bad I have changed the fluid and filter, it also seems to shift at a high rpm from 2nd to 3rd. Unless I you let off quick and go back on kinda like engaging a 2 speed rear end. Does it need a bigger trans cooler or is the trans shot

I have a farmer with a 2001 F350 SuperDuty with a 7.3 broke down at his farm a few weeks ago. Asked me to come look at it. No start issue. I use the Matco Determinator in my shop, so I take it with me for starters,after running diagnostics I come up with p0340, p0344,& p1670. After googling these codes I make the determination idm is bad. Farmer agrees to let me try one, install a new BorgWarner unit from O'Reillys, and bam truck fires up. I reinstall inner liner clear codes and go about my way. Few days go by and farmer shows up again, truck run a few miles around farm,spits sputters, and dies again. Go run my checks and same thing. Farmer told me in nthe beginning he had CPS changed per the recall. I had idm replaced under warranty truck fires back up, so this time I drive it , and get bout 2 miles down road truck dies. Had to tow strap back to shop. Got a new cps from ford replaced truck fires up. Farmer takes truck drives for bout a week guess what truck gets towed back. 3 codes are back, along with a few others related to low voltage. This time I replaced idm for a 3rd time, truck fires up. Today I let it idle for 3 hours in lot, decided t test drive, got less than a mile down road, truck shudders chi engine light comes on and it wants to die but keeps running. I am able to get turned around but it dies before I can get back home. Run codes and get same 3.

I have a 2005 Cavalier (60,000 miles) that's been having some transmission slipping in the cold weather. As the weather has warmed up, the issue has lessened but not quite gone away. We added a little transmission fluid, but I haven't yet had a chance to replace the fluid/filter. The check engine light has been on in my car since I've owned it... the shop I bought it from replaced the solenoid, but the code still hung around. Everything I've googled tells me that the issue could be the wiring or could be the solenoid needing replacing. My real question is... how soon do I need to act on this? p0741 p2761

I have a 2008 6.4 f-250. It has 139,00 Miles and I have a problem with the truck losing coolant and overheating on the interstate. When cruising 75-80 my truck will sometimes begin to puke coolant from the degas bottle and my cooling fan will begin to run. Engine coolant temp once spiked to 240 degrees before I could get off onto the shoulder. Around town the truck does fine although I do notice a loss of coolant but no overheating issues what so ever. I have the Dpf Deleted and Egr coolers are off. I run an H+S on a mild tune. Is there any other thing that could be wrong with this truck besides head gaskets? I am not looking forward flipping that bill. Trying the exhaust all other possibilities first.

I have 2000 ford f350 7.3 diesel. (Approx 95,000 mi). Tried to tow heavy wood chipper out of soft backyard, truck on angle because of grade. Put in low and second for better traction. After somewhat high engine rpm tires started to move me ahead until spinning occurred upon which I would immediately stop and try again (slowly). Next thing I know trans fluid on ground and truck steaming. Let cool down, refilled trans oil to proper level, unhooked heavy load. Fluid NO longer leaking, drive home fine (towing nothing). What are my next steps? Very concerned I've done grave damage!?

I just bought this truck for a pretty good price it has 225000 on it the engine was over heating. The guy put new rad, new water pump, new fan clutch, and a new heater core with thermostat. The truck still over heated so I pulled the thermostat to see what happens and the truck over heats even faster. All this happens while driving regardless of ac on or off. I got a motor and put a motor in it with all new pump and thermostat. I put new coolant in and flush radiator. I cut a hole in the cat to see if the cat was plugged for the truck seems to have low power and sputters. With in 1mile the truck over heated dumping all the coolant out of the system which the truck did as well before. Will the diesel rad work in this truck I have a diesel one I can put in since its a bigger rad?
