Re packed / cleaned my hubs. Did a 600 mile trip and front driveshaft is locked again. Am trying for first time soaking them. They are in tranni fluid right now. I can't afford warn hubs. Is there any other tricks? Or will I have to soak them every few months?
View 13 RepliesI've got a 7.3 tranny that has had ELC Coolant and water mixed in with tranny fluid because of a bad radiator. I drained the fluid from the tranny a week ago and when I pulled off the pan today there is still junk in there. I'm planning on putting in a new filter, gasket and Mercon V but how do I clean the old stuff out of there? Picture.....
View 14 RepliesOn my way to see my folks and I started feeling a vibration like driveshaft or wheel bearing between 45-55 mph then at about 75 then BOOM! Pulled over and found a pool of ATF thought my stock 4R100 just bit the dust but looking at it the fluid is coming from the front driveshaft at the Tcase. My hubs are unlocked and my ESOF is in 2HI but I assume my tcase was locked. Also since the tcase is probably screwed I'm goin to do the 271 with manual hub swap, how hard that is?
View 10 RepliesOK, so a friend's F150 just went up in flames in his driveway and he told me that the problem was the hot link behind a plastic/ rubber barrier at the main brake cylinder. I had a recall notice on my old truck but since I left the US and took the truck I never paid much attention to it, thinking typical overkill. Now I already heard from another buddy who caught lit brake fluid dripping onto the front tire and got the fire out before it spread and looked up the info today. Looks like our trucks are affected. Best to unplug the harness that goes into the brake master cylinder will prevent this problem from occurring? I never use cruise where I am, the roads are too small and slow.
View 6 RepliesI was out with the F350, drw, automatic, 7.3, 4 x 4, yesterday about 30 miles from home base. The transmission started pumping fluid out the front like I have never seen before. I am not talking a drip, I am talking a stream, a big one..... almost like pouring coffee from a coffee pot. I noticed it when I was backing into unload and was leaving an oil trail, a quite obvious one.
We took off the tc cover as it was coming off that to find a dry tc and flywheel, but fluid running out off the case. This is the second time this trans left me high and dry in 165k miles. The first time was a stripped tc/ input shaft. We repaired the transmission then but I don't think we replaced much besides being sure no debris went though everything, fixed what was broken. That was about 25,000 miles ago.
Warn Premiums, installed them and now the 4x4 is engaging, but still have a grinding issue. When the hubs are locked and the switch is in 2 wheel drive, the frond end is grinding, if I switch it to 4 hi, the grinding goes away.
View 3 RepliesMy brother is having a issue with his 99 F350 diesel automatic tranny pu. When in manual 1rst gear the engine stumbles and runs like crap. In drive or 2nd gear it runs fine. He's getting a code for a bad cam sensor. A new OEM and aftermarket sensor has been tried with no solution to the engine problem. What might be going on?
View 1 RepliesI was spraying undercoating yesterday and noticed a trans leak, it looks like its coming from the top of the trans. Not a lot of fluid just enough to coat the trans on top. I tried using an inspection mirror but i still cant see the leak.
View 4 RepliesWell, get the engine running sound, then the drivetrain takes a crap on me. . . On my way home, about 60mph. Hear a noise from front drivers side. Gets to the point where I think I am losing a tire. Got out and checked the lugs, all clear. Got back in and the truck wouldn't move. Shifted thru all the gears, nothing.
Revved up to 1500rpm and it just sits there and shakes, like it wants to go but can't. No grinding or anything. Got a tow truck and as we were loading it, noticed that the front axle was rolling fine, but the rear was dragging. Tried it in N and D and it still wasn't rolling. Also observed drips on the flatbed and the drain plug on the transfer case was wet.
Praying that it is transmission, cuz I can just have them come get it and have it repaired under warranty. Heck its only got about 3500 miles on it. If its the hat to check? Ill be spending the rest of my evening on YT/Google. . . (Figured this was the right area to post this, cuz its a 99 7.3, I didn't see a dedicated drivetrain area so. . . )
Have 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.

Truck was running perfect down the road, then suddenly it lost power and started missing at all RPM ranges. So i keep driving another 6 miles and then POOF the miss is gone and truck runs perfect. Couple hours later i hop back in it and its running good and then suddenly it starts missing and loosing power again except this time it never started running good again. Never did throw a CEL.
I hooked up my SCT Tuner (for my F250) to check for codes and came up with P0171 which indicated one of the banks was running lean, but no missfire codes. Did a search on here and learned the common problems(vacum leak) of that code.
Found the vacum leak at the PVC elbow, so i replaced both ends of the plastic tube.
Pulled the throttle body elbow and cleaned out the clogged up EGR ports.
Put a new air filter in and took the MAF out and cleaned it with MAF cleaner.
Put it back together and it idled way better but still ran like crap with the bad miss/sputter. Ran it down the road a few miles and came back thinking of the catalytic converter, i crawled underneath and it was glowing red. It does run and feel like the converter is stopped up but if i have a dead miss and dumping fuel wouldnt that make it glow red to or no? Still no CEL and now no codes.
Also i held the engine at about 1000 rpms where i could here the miss good and unplugged the fuel injectors one at a time to see if that made a difference. Each one i unplugged made it miss worse, so wouldnt that tell me that all 8 cylinders are firing?
And i changed the spark plugs (motorcraft) 250 miles ago.
So it still cranks and runs smooth after a cold soak overnight and then after a mile of driving or less it starts the dead miss/sputter and loss of power.
So 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.

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 .
So just got a new pcm installed since i fried the last one anyway. I had a new trans installed almost two weeks ago factory 4r100 now i have a p0720 code. Id take it back to that dealer.
View 8 Replies1999 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.
