How important is the fluid swap and service of the transmission service at 30k mile interval. I have my truck at the shop now getting it done but was just wondering how important to have it done. My truck is just ten months old and already been 30k miles in it.
View 14 RepliesI just had my 04 5.4l engine rebuilt. Ive driven it about 500 mi and it started running rough at a stoplight. I tapped the accelerator and it started running good again but service engine light came on. I pulled the codes and they were P0022, PO345, P0340,and P0430. It has done this several times now. Everything was replaced including the phasers, except for the camshaft sensors. Could they cause this problem?
View 3 RepliesWifes F150 was turned off while she went shopping when she came out it would not start would crank but would not run. Got it home hooked up my scanner, had no codes, but the Service Engine Soon was illuminated on dash. Just wondering if this has anything to do with the PCM. Has a 4.6L engine, 2X4.
View 5 RepliesThis is my first Lexus and first new car in a long time. I have a 2015 3IS RWD and looking through the Services Guide I don't see any service interval for replacing the rear diff fluid or the trans fluid. All the manual says is under "inspect the following" check diff fluid level and check trans for leaks--and that the trans is a closed unit with no dip stick.
As far as my automotive knowledge goes, all transmissions are closed and yet many in the past have had dip sticks. Also, I've never heard of just topping off diff fluid if you're low. And both definitely have had service intervals! I change the diff fluid in my S2000 every 15K miles.
I find it hard to believe that the Diff and Trans fluid doesn't EVER need to be replaced.What are the service intervals for these two and the fluid weights?
I have a 2003 F-250 Super Duty 6.0 4WD that has about 202,000 miles on it. I bought the truck with 83,000 miles on it and have never serviced the Torqueshift 5R110W Hi-Torque transmission. No new filters, no new fluid. In the interest of gettting the most life out of the truck I am trying to be a bit more proactive with maintenance. Does a flush/power purge will precipitate transmission problems? I am even concerned that dropping the pan and changing the filters and topping off fluid may cause problems. There are no problems presently and the dealership can't tell me that the've ever performed a transmission service for the previous owner via OASIS. Can I get away with a filter change and fluid top-off at a decent interval without incurring a condition that will require the transmission to be pulled and rebuilt?
View 10 RepliesI have a 2004 f150 non heritage with a 5.4 its an ext cab lariat auto. It has 350,000 but has been well maintained. The truck runs perfect except sometimes I will hop in and start it up and when i take off it shifts through all the gears before 25mph and when i come to a stop it feels like it downshifts all at once and when i stop it will die. Again it only does this occasionally and the rest of the time runs A-1. This leads me to believe its an electronic error but it is not throwing any codes and cannot get it to replicate the symptoms for my mechanic.
View 2 RepliesPulled transmission out and it needs to be rebuilt front to back. My motor is generally stock but I'm rolling on 37" tyres so I'm thinking a stall converter and a "performance" rebuild. Looked at "Monster in a box" from Monster Transmissions. Truck is used at tymes to haul cement and heavy bed loads.
View 2 RepliesI got a 2004 F150 that won't go into reverse. All other gears work, including 4 wheel drive. I checked the linkage and it is working.
View 1 RepliesMy '04 Lariat 4x4 5.4L SCAB w/ 167k miles is giving me problems primarily while in O/D around 50-70 mph. When I lightly lean into the throttle either to slightly increase speed or maintain speed while going up an incline I get some jolting coming from the tranny. It's not a one time jolt when it downshifts but a repetitive jolt while staying in the same gear.
It doesn't happen until the engine is up to normal operating temperature and happens almost exclusively when O/D is engaged. It's thrown a code which I'm going to have pulled today while at lunch (will follow up with the code once I know what it is). When the check engine light has come on I can push the O/D button to go into 3rd gear and it will still shimmy the truck a bit but when I go back into O/D it seems to calm down.
I'm thinking it's s sensor and I'm aware there are a few that talk to the tranny. What could be causing it. It started late last summer but has progressively gotten worse. It's a daily occurrence and road conditions and outside temp don't appear to make it worse or better. One more thing to note is that the jolting is significantly worse when in 4x4 high which makes sense since it's affecting both the front and rear axles assuming it's coming from the tranny.
So I started hearing a noise that sounded like a telegraph clicking in random intervals. Some days, no sound while others I thought I was an old Western Union Office. Now the sound has progressed into a sound that almost sounds like a small compressor. It sounds at each start up and then at different points during the drive. I have traced it back to this device. It sits to the left of the Air return behind the glovebox. I have two pics to illustrate. It is the black box with a small wiring harness plugges into the top. On the left side there is a cylindrical white piece that is part of this device. Everything in my car works so not sure what this thing does. It looks like a royal pain to get out as one of the bracket screws is down in the back so that screw will be tough to get to without dropping the blower housing. That may require pulling more things like the dash when they replaced the evaprator.
View 5 Replies2008 F150 Super crew 5.4 v8, bone stock. The truck was acting up with a rough idle and slight miss when in gear at a stop 2 weeks ago, loss of power going uphill. Changed fuel filter and filled up with premium and a can of sea foam. The truck straightened up after that, so I thought. Last Friday it dies in the road, cranks, but no fire.
Has to be the engine, had it towed to the local dealer and they get to look at it Monday afternoon, said the transmission fuse was blown and it keeps blowing new ones, it's in the transmission wiring. I am used to older trucks and was blown away transmission wiring will shut the truck down. I would think the wiring harness to the transmission would be simple enough to check out, can the wiring or solenoids in the tranny cause this?
Transmission won't go into drive until I give it gas and then hard shift between 1&2 then a little slipping when I get on it in higher speeds , fluid and filter brand new, threw a speed sensor so code I replaced with new but no change, don't know what to do and can't find out why speed sensor code went off changed but didn't fix? Can't drive truck!!!
View 3 RepliesSo last night my trans have out, going up a slight grade, all of a sudden the engine revved and I had no more 3rd gear. I've done some research, looks like rebuilding it is the only option. I've got my Mustang GT to drive in the meantime, so I am thinking of rebuilding it myself. The truck is an '07 F150 5.4 2WD.
View 7 RepliesWell it seems the transmissions POOCHED. It feels like its binding especially in reverse, and makes a whining sound in park/neutral. I guess, I will take it to the trans shop tomorrow and hope for the best....
View 7 RepliesI have a 2008 Ford Lariat F150 with 53k miles. The transmission seems like it slips at times. Here's the scenario. When I take off from a standstill and going through the gears at a normal acceleration pace, say I momentarily lighten the acceleration pace then try to resume. At that point, the transmission seems to slip momentarily, then bumps back into the pull mode. It feels like there is slack in the drivetrain until it re-engages, or like the lockup torque converter momentarily releases until the computer has time to react to the accelerator positioner calling for more. One guy said the transmission is, at that point, between two gears... either trying to decide to downshift or to upshift, but you can feel the surge in rpm momentarily until it decides ... then bump and your off and running again. If I push the O/D button, it stops doing it. What I can do? Because the dealer can't seem to get it to act up when they test drive it. It does it fairly regularly on me though.
View 4 RepliesI have an 07 with a 4r75e transmission that has developed a leak. The truck has 60,000 miles on it. I looked under the truck and it is not leaking from the pan. I plan to put on stands and get under it tomorrow to see if I can find the leak. Where I might check for the leak?
View 6 RepliesI have a 2004 4x4 with 305K on it. Never changed the transmission fluid and I think its slipping a bit.
Beentold that I should not change the fluid because the new fluid would somehow damage something and to just not worry about it.
So OK to change the fluid or not?
I have a 2005 f150 xlt. Ext .cab I never changed the transmission fluid and filter
I have a problem now, the transmission do not go forward only reverse.
My 2005 4.2 L transmission slips in overdrive but I turn off overdrive and it stops slipping instantly. What could be the reason for this does this require an entire trans rebuild or is it an easy fix.
View 1 RepliesMy transmission failed on me again last night, truck won't move (I still seem to have reverse). Was cruising down the road at 85km/h and Trans Failure came up with a P0720 (OSS sensor Cct.) and P0722 (output shaft speed sensor no signal) codes. The first time I only got a P0721 code.
This is the second time in 6 months. Last time I spend 3200 to get it rebuilt locally. i don't do any towing, I don't spin my tires etc. and I haven't taken it off pavement since it was rebuilt so I'm not sure why this is happening. I baby my truck.
I have the 4R70E in the truck now, will the 4R100 fit? It's suppose to be a heavier duty tranny correct? Where I can get one and if not where I could send mine to have it reinforced?

I purchased this truck about 2 years ago, with about 70k miles. Previous owner had transmission work done, but I'm not sure if it was a rebuild, new, or refurbished. About 8 months ago I experienced hesitation, and frequent stalling when coming to a stop. Pulled the engine codes, and they said it was throttle body related. I thoroughly cleaned the throttle body assembly inside, with the battery disconnected, went through the idle re-learn process, and it drove fine for a few days. Took it into the shop, and they did a tune up and replaced several plugs and coils. Since then, it's run great.
A couple of weeks ago, a whining/buzzing noise was coming from the engine compartment, getting much louder as RPMs increased. Got the oil changed a week ago (it was overdue), and the tech at the quick lube shop said the noise was from the drive pulley(s), and that they should be replaced.
Today, I was waiting for the parking lot at work to open, sitting in park. I quickly switched to Drive, and the trans didn't seem to engage (Auto Trans). The engine revved, I let off the gas, and it then engaged and I scooted into a parking spot. After work, on the way home, there were similar issues at the beginning of the drive, mainly when slowing down/stopping/down-shifting. Most of the drive was on hwy, and I managed to get by okay going around 60 mph, with some spikes in RPM's occasionally when I would accelerate (no Tach, so I'm going by sound). Half way home on the high way, the O/D Off light starting quickly blinking, and the odometer screen read "TRANS FAULT". I managed to make it off of the highway, and stopped at the first red light, where the engine stalled. Turned it back on, put it in gear, and it drove fine for about 5-10 minutes on back roads, with no lights/notices. The last 2 miles home I experienced a lot of slipping, and high revs. When I backed into my parking spot, there was noticeable leaking... Trans fluid was leaking fairly quickly. I hadn't noticed any trans fluid leaking before today... I went out to run the engine and take a short trip to warm up the fluid to get a reading, but it wouldn't engage in Forward or Reverse at all. Pulled the dipstick out, while "cold", and there was nothing... I'm assuming that it's drained drastically, and is extremely low or gone.
