Ford F-150 (2004-2008) :: 2007 - Trans Slipping / Hunting For Gear
Sep 28, 2011
Here's my transmission problem. 2007 f150 crew lariat 4x4 with a 5.4
When my driving conditions force me to cruise at the 28-30 MPH range my transmission often hunts for an upshift, like a slipping gear hunt then it hits in firm. It must be from 2nd to 3rd gear I'm thinking. It doesn't occur at all if i am accelerating through this gear or past this shift point. under normal acceleration through and past this speed or shift point it is as smooth as can be.
I often drive some flat but winding dirt roads out in a forest area near my deer camp and it seems this is where I settle into a speed of 28-30 mph for several miles at a time. This is where it happens, the transmission seems to begin to shift but seems to slip or hunt for that next gear then it hits in fairly firmly.
Truck has 83k on it....

Feels like my transmission is slipping from 40m/hr to 65m/hr. But only when I am at a constant speed and not when i am accelerating. only happens when I am at approximately 1400rpms and while in overdrive. Does not happen in any other gear just overdrive.

The reverse gear in my F150 has started slipping all of a sudden, with no noise or notice. All forwards gears are functioning properly. If I rev up the motor in reverse it seems like it wants to go, but I get the wrench light/safe mode and it now has a P0720 code. I've done some research and replaced the Output Speed Sensor and replaced the tansmission fuild and filter. I cleared the codes once before I changed the sensor, and now my reader indicated the the P0720 is "Pending". Do I have to keep trying to use reverse? Drive it more? Plus it looked like after driving it today that I might have overfilled the transmission.

So ever since I picked up the truck from getting the springs swapped out the tranny has started to slip more and more. It's about at the point now where it does it at the 1-2 and 2-3 gear change every time unless I give it a little throttle so it shifts harder. It's just the normal shifting pause and then the slight jerk when the next gear starts. Time to a new torque converter, or am I looking at getting my whole thing rebuilt? If it's the converter I can give that a shot myself but if I have to have it rebuilt it's going to have to wait until January or February.

I have a 99 Ranger 3.0L automatic, ext cab, 2 wheel drive. Door sticker show code "T" which I looked up as the 4R44E. The trans seems to be slipping in 1st and 2nd. Thought it was "reared shudder", from a "limited slip" differential but mine is not limited slip. just the regular 8.8 with 373 gears.
Wanting to know what if any options I have for buying a new / rebuilt tranny? I've seen where depending upon the year and motor, Ranger can have 4r44e, 4r55e, 5r55e, etc.

It does not like to stay in 5th gear, drops out to neutral. 2001 Accent Hatchback. 1.5l 5-speed
The other day it started slipping out of 5th gear on the expressway. Held good for the first 10 to 20 minutes. Afterwards I had to hold it in 5th for it to stay in gear. While holding I noticed it pushed on the shifter when applying throttle, and let up some when I let of the gas.
I inspected the pivots at the transmission. The forward / back bushing was not installed properly by the previous owner. I rigged it up better with a fender washer and cotterpin. It previously had just a pin and the bushing had expanded out. This removed the play from shifting I had previously noticed. It also halfway fixed the popping out of gear. It stays in gear a little longer, and when I put it back into 5th it stays there for a while most of the time.
I have not inspected the lubricant level yet. Where to check next?

My 2007 F150 XLT, 5.4L, 4X4: 3 times in the past 4 months while towing a small trailer a message comes on in the dash display "trans fault" and the OD OFF flashes on the dash. What is the fix?

I have a 2008 F-150. When moving gear selector from park to either reverse or drive, trans has a delay engaging. After engagement, it runs fine, shifts ok, downshifts ok....

2002 CAvalier 2.2 automatic with 123'000 miles. I was asked to look at this car for a slipping trans problem.
I drove the car about 3 miles and in 1st and Reverse it feels normal, even on a steep hill, but once it shifts into a higher gear the trans slips and you can go only about 15mph.It is shifting, because if you move the shifter into a lower gear while traveling....you can feel it downshift.
There is a code of P0502 Vehicle speed sensor. and there is no Trans fluid visible thru the filler cap on the trans top.
Previously someone else worked on this car for the slipping trans....changed some sensors....but couldn't fix the problem. The owners don't know what parts he replaced. He works for a Tire outfit and I've known him to lean towards used parts a lot.The previous mechanic convinced them that it needs a new Cluster. I presume he means instrument cluster.
I have a feeling that he just threw parts at it hoping that something would stick.
I presume that he replaced the VSS, and it didn't cure the problem.Come to think of it....the code could be from before the other persons work. I should have cleared the code and test drove it again.
I'm looking at dropping the pan, replacing the filter, refill the fluid, and replace the VSS
My questions: Could a instrument cluster have anything to do with the shifting problem.
Is the level of trans fluid supposed to be above the ledge under the filler cap, or is there a "full level" plug in the side of the trans. If he replaced the VSS with a new one....and the fluid level is good....whats my next step.

I have been running SRL and love how it woke the truck up, however it seems like it hunts around a bit for the right gear sometimes and feels like it is constantly locking unlocking TC. I recently switched to 8K tow because I am going to be pulling a horse trailer soon and wanted to see how it felt first and it drives way better. I miss the extra getup and go of the SRL but it shifts way better and doesn't hunt around. Is there some adjustment on SCT I can do that would fix this issue with SRL tune?

I recently had my Transmission flushed at 90K (beyond the 75k). I had my Struts replaced and Full differential service. They found the Carrier bearing Center Ring was blown out said my truck was fine to drive until the part came in. I drove my truck home and it wasn't until I put about 20 miles on my truck did my truck start to slam into 2nd gear. It goes gentle if I accelerate slowly and eases with I turn the OD off ( but I only tried a few times). I have tried a few forums and there are so many things that it could be.
Everything was fine until I had this servicing and they took my truck apart. On a separate unrelated issue I have a check battery light on, but it is a brand new battery. I had my stereo changed out a year ago and the shop said it was the battery failing (only 1.5yrs old). Just though I would throw that in just in case a COMPUTER issue gets thrown out there. My truck has been running fine before all this SERVICING was performed...

2008 Hyunda Accent, 5 speed, with high mileage. She claims it slips out of 5th gear when she's driving. They're on vacation, the car is in the shop, the shop is saying that it can't find the problem...
Apparently it slips out under load (in constant motion).
It seems that it only occurs when the transmission is hot, meaning the oil has less viscosity. The dealership apparently is saying they can't find anything wrong and she isn't making it up since she said she drove from Michigan last week with her hand on the shifter the entire time to keep it in gear. Dealer is saying they aren't going to just drive it around and around until it happens.
How modern cars are built these days. I know older cars had some synchro things that would wear and allow the shifter to pop out of gear, but I read that some Hyundais have cable driven shifters....at a loss.
It happens in 4th sometimes, too, and will also pop out even when leaning on the shifter.
I did see this thread, but was wondering if there was any additional information: [URL] .....

We have a 2010 Santa Fe AWD LTD with about 140, 000km on it. It recently came back from front suspension work. The suspension is fine now, but we notice harder shifts in the transmission. Also, there seems to be a vibration just before shifting gears and when under load (like going up hill) seems to slip (like on ice) about once every second until the shift is made. Once the shift is made it drive smoothly until put under pressure again. Even stepping down a bit on the accelerator will cause this slipping feeling (or maybe its loss of power). Just had new plugs put in and a tuneup so it's not that. Could something from the suspension work cause these symptoms?

Like the title says. 04 Explorer.
No transmission issues ever. Immediately after doing an oil change myself for first time, get some transmission dropouts, slipping out of gear at stop lights, waiting way too long to go into 2nd, etc.
Then, started getting OD off light, and service engine. Error codes show something about wrong setting for 2nd, 5th, solenoid error... a bunch of 'em.
Anyway, guy at parts store says I must have knocked a wire loose causing misreads between cpu and transmission. It's a real pain getting under there since I'm using jack stands, so exactly what I should be looking for or at least the exact name of a connector or something so I can look it up.

I have a 2008 Accent (base model for the most part, no C/C), and my transmission seems to be slipping a bit. The symptoms are: slow acceleration, a delay in gear shifting, and after the 30MPH mark, it takes forever to get up to anything near 60. I just wanted to know if it's a simple solution such as topping off the transmission fluid, or if it's a bigger issue.

My wifes 04 explorer 4.0 4x4 slips in between second and third gear and you cannot manually shift the gearshift below 3rd gear. I assumed tranny was going out but was told that it could be the transmission control solenoid or the transmission control switch (i think they are the same thing). I read that the most common symptom of this going bad is a slip between second and third gear. Haven't checked codes but will when i get home to see what it comes up with. This is the messed up model where you have to add fluid underneath through the drain plug. Was going to change fluid and add lucas to it to see if it remedies the problem.

I 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?
