Recently started getting a P0720 for OSS on 4-6 pound launches, and the X will lurch and then stall out. It drives fine when I drive like a normal person, it also launches fine at 8psi and up (obliterates the tires in the process). Little curious as to where I should start looking beyond the usual culprits on checking the connector for corrosion and verifying the sensor itself is clean/still good.
Stupid thing drives like a peach everywhere else except the 4-6psi LAUNCH ONLY range. Normal driving through that pressure range is absolutely fine. 4-6 is the only problem child area.
Just got the transmission rebuilt in my truck and other then shifting hard sometimes it has been doing great, Hooked it up to the goose neck this evening and everything was fine then went to back it up and pull it forward and after a short distance the od light was flashing and when i ran a check on it it was p0720? The transmission has less then 1000 miles on it?!?!? 1999 Ford F-250 7.3 Automatic....
View 5 RepliesMy friend has just brought a truck and has lost 3-4 gear in the auto trans. We have the PO782 code coming up. Is there something in particular we should look at first.
View 2 RepliesI have a 2003 Ford f250 5.4l brought it to the shop today and they said the pcm isn't communicating with the trans. The truck hesitates and stalls out at a stop. idle is OK a little studder. OD light blinks also. I put new ho2s in, new oss from ford, new plugs and coils (motorcraft).
View 3 RepliesI towed my 32 ft/ 600lb travel trailer 115 miles into arkansas today. When I arrived at the campground, the engine was running rough and shaking the vehicle. I saw highs of 175 (trans temp) 1150 (EGT), 214 (ECT), and 224 (EOT).
I recently installed the canned trans tune from my new SCT X4.
I pulled codes (none), checked cylinder misfire count on scangauge 2 (none). In fact, all gauges on the SG2 were within spec. I popped the hood and let it idle for 15 mins. Temps all dropped down to what I usually see after normal driving (not towing).
The engine did start to calm down as it cooled, but still sounded a rough
Picked up my truck from the local transmission shop yesterday and on the way home (less than 3 miles away), I noticed the ABS light was on. I turned around back to the shop but the guy behind the desk couldn't pull the codes (his mechanics smart with codes don't work Saturday). So I will head back tomorrow when his code-smart dude is back but was wondering is there anything they could have done during the tranny install to muck up the ABS system? Or do they need to do something because of the new transmission?
I checked the #15 5-amp fuse under the steering wheel but it looks good. Truck runs good to me and shifts fine in the 10 or so miles I drove it yesterday but I'm not savvy with transmissions or ABS.
Shut my truck off for about 15 minutes and wouldn't start back up. Installed new fuel filter. And gonna try changing cps. Torque says Rpm 180
Ipw. Bouncing between 600 - 3000 Hpop. 250 while cranking Voltage 10.9 while cranking. Ipr starts about 15% and slowly climbs to about 88%
Fuel pressure about 65%
Tried unplugging cps. Gonna check oil now though I check it every time I fill up and it never uses any.
Title says it, I just installed my Hydra Chip, now my edge says it cant communicate with PCM. I have checked all the connections on the edge, all is good. I planned on just using the Edge only for gauges. Will it not work anymore now that I have a Hydra? If not I will just sell it and buy an Edge Insight, so long as that will work.
I think its the Edge EVO 2, its this one.
How many gallon tanks were installed in the E99s?
View 6 RepliesPut in my new S&B intake today and when I stomp on the gas I am getting a loud shuddering noise from the intake when I change gears. Also sounds like a squealing sound sometimes. Doesn't sound like other trucks that I have heard. What that could be?
View 14 RepliesHave to get rpm's over 2k before trans will engage, then in between shifts I either have to let off throttle or let engine rev over 2k to get trans to shift...
View 3 RepliesI'm getting a sound every now and then of what sounds like i'm running over rumble strips on the side of the highway. I'm guessing it's the trans grinding. Any thoughts?
View 8 RepliesI notice my trans temp gets really hot fast. For instance just moving my trailer from front of my house to side yard makes temp go to 250. Without any load and driving a couple miles it does the same thing. It's been doing it since I installed the trans temp gauge just trying to figure out what's up.
View 14 RepliesI bought this truck with 200000 miles and its been flawless, its now 900 short of 600000.. I use it to haul everyday.. nothing heavy mostly a car or truck and every once in a while a skid steer. I got 560000 out of my trans, i take it easy. lol
at 350k I installed a Jw valve body drilled pump, tripple disc converter and solenoid pack.. at 560k it went, i pulled it and brought to a guy i trust as much as you guys trust BDS.. Ive had what Ive called a vibration since day one, could be a shudder, could be a shimmy.. what ever.. I brought it back and he says nothing would do that from a trans, so I went through drive shaft, new t case ripped apart rear end and its still there and I have just been dealing with it.. about 2 months ago it started acting up in first. when I pull down to drive I get the normal bump and start to go, it feel like the truck slows, then another bump and it climbs normally with the shudder.
took it back and he said maybe a stuck valve in small VB, so I pulled it and went down there and it was fine, I reinstalled and still does same thing. I then put a pressure gauge on it and it swings as it should sits around 70 psi and will climb, only in first it will climb and fall back to 70 like a switch was flipped, and the rest of the gears bleed off slowly or normally.. He then said it could be the big valve body, so I swapped that one out with another and no real change, maybe its a bit more noticeable.
I am at a loss. Could this be loose feed bolts? Could the shudder that I can feel at most speeds be the 1 gear slipping a tiny bit all the time? I am told that first gear is always on.. this truck has been a dream until this trans issue..
I've searched, and gone back through my computer history and can't find it. I have seen a thread here which Mark contributed too which said what the max temps were and for how long etc. I know book is 230 and optimum is around 165 but there was some degree of play in that.
View 8 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.
2000 f250 7.3 powerstroke dp chip stage 1 camshaft and 180/100 injectors coming at some point but stock for now
Well stock trans went two weeks ago so warranty company had another stock one put it (4r100). Finally got the truck today and I noticed my overdrive was flashing. I have no issues though shifts fine speedo works Rpms are normal I checked fuse 19 under the dash that's fine so I'm lost
If I turn the key on I can use the button like normal but once I drive it just flashes. It works but flashes .
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.
2001 7.3 auto, 2wdr, 291,000, Transmission sometimes shifts hard from 1st-2nd, 2nd-3rd. Problem started after I found trans dip stick tube broken and loss of fluid. Anything I can do without going to a shop. I've replaced the Broken Tube.
View 2 RepliesIv heard a few things about changing the valve body. I tow a trailer so was wondering on pros and cons of changing this. And also what brands are recommended.
