So I have installed a 331 stroker with an AOD trans in an early Bronco.
The question is... What is the correct procedure for getting the lock up converter to function? How does it need to be wired?
2000 Explorer 4.0 dohc avd. 150k miles. The torque converter lock-up function has started to drop out. It can happen after some miles and will light a warning light in the dash that the manual states as "contact tech" or something like that. Everything gets back to normal with just a "blip" to "off-position for the ignition switch and might stay normal for all between 5 minutes to several hours. Seems to me it is an electrical issue. Dirt, sensors?
Runs and shifts fine other than this. Only thing I have noticed is that the temp gauge reads pretty low but I think this started earlier and I understand that the temp gauge has its own sensor. Where to start looking?
Vehicle: 1994 TripleE RV based on Ford E350 7,3 Diesel, 70000 miles.
My trans is skipping out of lockup for 1-2 Seconds and then goes back to normal operation with lockup engaged. I am shure that it is the lockup disengaging because the increase in rpm is not as much as between gears.
This happens appr once or twice every hour when driving at normal constant highway speed. It happens both in 3rd and in OD. There is no flashing OD lamp, and the OD button is working (I use this actively when going up hill to keep up momentum and rpm)
I am not able to find out what causes this. I have replaced the speed sensor on the rear axle, the rpm sensor on the engine and the brake light switch on the brake pedal. Replaced one item at the time to be able to determine if any of these items was causing the problem. But none of them made any difference, the problem is still there. I have also inspected the harness connector on the trans and it seems fine to me.
I have problem with my Ford F-250 7,3 diesel SD from 99' XLT transmission 4r100 . I have changed torque converter and now something leaks between transmission and this converter. What can it be? Is there gasket which must be changed ? I didn't notice anything wrong with it.
View 13 RepliesAnything besides a worn out Torque Converter clutch that might cause the incredible amount of shaking when the transmission tries to lock the TC?
View 6 RepliesLooking for the fuse that controls the overdrive torque converter clutch/lock up/engagement. Had a look in the owner's manual, didn't find anything. Pulled a couple fuses that I thought might be the one, no go.
I had found this fuse b4 but now a couple years later can't remember which one it is and can't remember where I found the info on what # the fuse was.
When running up through the gears under normal acceleration I can feel almost a double shift in 5th gear. It doesn't occur using tow/haul so I assume it is the TC locking up. Everything else seems fine. Truck has 9k miles, mostly towing. 2016 6.2 ....
View 6 RepliesI was driving my 7.3 down the road and it started acting like the trans was slipping, it revved up and tried kicking down a couple times and when I slowed down and went to speed back up it just had no power coming through the trans to the wheels it just revved. I put it in neutral and it idled up for about 5 seconds. I put it in park n shut it down. I fired it back up after looking everything over and it moved about half mile down the road and no power to the wheels again. The trans is full of fluid, is there a sensor that could of went bad or just the torque converter or the entire thing shot? Only owned my truck 6 months has a trans and motor swap already from previous owner. 180k on current motor n Trans. 382k on my truck. t6 4" turbo back banks exhaust only mods I know of.
View 11 RepliesHave a 2004 hyundai accent and I think I am having problems with the torque converter locking up in a timely fashion. It typically takes 15 to 20 minutes when I am driving on the highway. Is this normal for it to take that long? My gas mileage is terrible (22 mpg last fillup) and I am thinking its related to this.
View 7 RepliesA4LD transmission NOT RELEASING LOCKUP in both 3rd and 4th? My 1991 Ranger 4.0 will get into lockup sooner than normal(comparing the recent past), and would stay in lockup long enough to make the engine shudder when I slow down to come to a stop. (much like holding 4th gear without putting in the clutch when you approach a stop.
It doesn't die out and does shift into the proper gear but only after the RPMs dive down to probably 400 and the vehicle shudders a bit. Received and replaced the throttle position sensor today, looking to do the vacuum modulator this w/e. Any other possibilities?
I have a 2005 Prius with 120,000 miles on it. Today the red triangle light and circle warning lights came on. The service department at my dealership said, "inverter converter losing function. No longer able to accurately control voltage". The car seems to be running the same as it always does.
Specific things I should have checked?
In the "Old days" I could pull the one-and-only coil wire and trigger the starter motor to rotate the converter so the plug was at the bottom. How do ya do this with COP engines so the engine does not start?
View 4 RepliesHow to drain the tranny fluid from the torque converter , I am dropping the pan and installing new filter and fluid, I want to get as much of old fluid out as i can It has a 3.0 engine with overdrive...
View 11 RepliesI have a 02' f150 v6 67,000 miles. When I come to a stop, the trans shudders abit like the converter is still locked up. It then goes to stall in a few seconds. this does not happen all the time, fluid is clean. I understand there is a simple fix for this, or is this normal?
View 1 RepliesSo my transmission drove perfectly fine I just wanted to put an upgraded torque converter in especially after driving a customers' truck with a low stall converter. I know their not like for racing or anything but it's a work Truck with some mods to the motor nothing crazy. So I went ahead and bought a low stall triple disk converter and I drove around the block fine and went to go on the freeway and got into fourth but lost it as I hit 75 (was not flooring by any means and had it in the stock tune) now it will not go past second gear. Once it did this the o/d off light started to flash and I decided to do a stall test.went to 1800 in a Second. Suppose to stall around 1200-1300.

1999 7.3/4r100 4wd with the rattling torque converter.
I bought this truck 10-11 years ago to use as a tow rig for my landscaping company. It has been a great problem free truck, I have done brakes a few times, a water pump, ball joints but no issues with motor/drivetrain.
I don't know the history of the trans before I purchased. Ford didn't have history of it being replaced and even now it still has all the labeling on the case. I would have thought it would have been washed off in a rebuild. Again I don't know. When I bought the truck it shifted nice and crisp, having owned trucks before it made me think it had been rebuilt but this was my first and only 4r100. Other trucks are ZF6 manuals.
Anyway 10 years and 100,000 miles later it still shifts very crisp and fluid, has been changed a couple times, is nice and cherry red. I added a 6.0 cooler, temp gauge and filter. Never see the temp rise and haven't seen much in the filter.
About 25,000 miles ago the TC started to rattle, a known 99 problem. I figured surely the trans would go and I would do a rebuilt from Ford. It keeps going though so being a work truck I have kept running it.
A couple weeks ago the starter just spun and wouldn't engage. I pulled the inspection cover and noticed some missing teeth on flex plate. Got it to start my turning crank bolt a bit to good teeth and the starter caught. Now we are carrying a breaker bar and socket. It has happened a few more times so I need to replace flex plate.
Question is, since I need to pull trans to replace flexplate, should I replace TC (I would like to get rid of the noise)? Some people have said I will be replacing trans in a couple months if I mess with it. They say just spend $3000 on a rebuilt now with a converter. Not trying to be cheap but hate to just dump this trans that is still working great and has served me well.
I have replaced many transmission and done clutches in many trucks so I am familiar with the steps of removal and installation, just stuck on what I should do.
Ok so here is my problem now. I'm sure its in the tramny but not sure what else. My shift from 3-5 has always been a little hard. Yesterday on my way to work I noticed shifts 1 thru 3 were hitting hard. Once I got up to 65 mph it was okay. Then pulling into work when I shifted to reverse it didn't go into gear right away and then it would hit into gear. Later that evening on my way home from work it was shifting the same but seemed worse. Then my tow/haul light started flashing and it seemed like the torque convertor wouldn't lock in. It would just stay in 5th gear and the more throttle I gave it the rpms would go up but I would only get a little response from it. Then a few miles down the road it just completely shut off on me. It will not even try to turn over. I could also hear a noise coming from underneath the truck. Something ive never heard before. I really need to figure this out
View 14 RepliesReplaced Troque Converter, Truck runs engine runs fine transmission won't shift out of 1st gear.
View 2 RepliesSo here I am driving away for the fuel station and then the tranny tries to shift and I hear and feel a loud clunk followed by no power. I have had no previous issues with the tranny but I believe it has not had any previous work done. The truck is an 02 7.3L with 200500 miles. I am guessing the torque converter is the culprit it still had very little forward motion when I tried to move the truck didn't matter what gear I was in. I intend to have the tranny beefed up but don't intend to go crazy. I do tow an 11,000 lbs TT on a fairly regular basis and have a PHP 6 position switch which can be set for as much as 120 hp from stock but don't do any hot rodding. I am mostly just looking to beef it up and provide as much strength towing.
View 2 RepliesSpecifically for a 2006 Expedition 4R75E . What the stall speed of the converter for this truck is supposed to be? The reason I ask is that the converter seems rather loose. At any point during acceleration the converter will allow the engine to rev up to 2500 RPM, depending on how hard I press the gas.
During normal (for me) acceleration the engine will come up to 2000-2200 rpm and just hover there through all 3 gear changes, then when the vehicle is up to speed and I let off the gas, the converter will lock and the rpms will settle down to something less than 2000 (assuming I'm not going over 75mph) if I press it a little harder, the rpms will come up to about 2500 and just hover there through all the gears, then lock when I let off. the only time a gear change will result in a lower rpm is if the engine is spinning over 2700(ish) rpm.
I'm not sure there is a problem, I'm just curious what the stall speed is supposed to be. if it is supposed to be a 2400 rpm converter, then the behavior makes sense, but if it is supposed to stall closer to 2000, then I'm thinking it might not be working as designed. I've tried to find this on my own, but I don't know where to look.
My 94 e4od does a few things. It doesn't seem to engage positively all the time. It doesn't grab well in manual 1st, but does in D. I had the FIPL reset at the dealership and he said he never saw a FIPL needing to be set so far one way. Also it has overheated a few times. Either the TC doesn't lock up correctly or its just not all the way in gear (if thats possible) I changed the fluid but it did it again recently.
Also the speedometer is jumping around like a nut case, the abs light is on...sometimes, when I have the headlights on and put my right turn signal on it feels like the TC locks up. Oh, yeah the lights are all jacked up in the back. The left turn signal light also has a small amount of voltage when I put the headlamps on (my test light lights up dimly) I thought it might be the multi function switch so I removed that and cleaned the connections. Nothing changed but I dont think that was it. I have troubleshoot this all day and I don't have too much of a clue to whats going on.
