Ford F-150 (2004-2008) :: Reverse Gear Slipping Suddenly?
Nov 7, 2013
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.

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....

it's a 2000 honda civic EX. I pulled into a parking spot and slowed down, then decided to speed back up and when I accelerated it was like the car was in neutral. No gear would drive. Turned off the engine and re started and it shifted and did fine then about a 1/4 mile down the road the same thing happened. It just switched into neutral. The transmission fluid is full and clean and the filter has been changed. There was no warning signs at all.
The only caveat I can think of is last week at 15 mph my front passenger wheel fell off after someone replaced a tire. I traveled less than 10 feet on the wheel. But didn't think the transmission would be low enough to hit the ground.
At first I thought transmission clutch but it would be doing it in one direction? Then I thought maybe a pump? Or could it be a sensor or the torque converter.

We had 2 Trucks that had the reverse go out in the last month. What would be the cause ? Is there a defect in the Trans?

My son bought a 2008 Fit new. At about 16K miles, the clutch suddenly started slipping. He barely made it to a dealer and it was replaced at no charge. Recently, the clutch suddenly started slipping again at ~32K miles. Before you say he's hard on a clutch, he drive a 95 Civic with no clutch troubles for over 140K before selling it to buy the Fit. He took the Fit to another dealer (he's in a different state now) and was told the clutch is OK, they drained some fluid out. Would excess fluid cause a problem -- after 16K miles?

Tranny started acting funny recently...shifting hard into reverse at first, then last night it was like it was stuck in high gear or slipping on the way home. Limped it home and took the following codes:
P0743 TORQUE CONVERTER CIRCUIT ELECTRICAL
P0750 SHIFT SOLENOID A MALFUNCTION
P0755 SHIFT SOLENOID B MALFUNCTION
P0760 SHIFT SOLENOID C MALFUNCTION
P0765 SHIFT SOLENOID D MALFUNCTION
P0962 PRESSURE CONTROL SOLENOID A CONTROL CIRCUIT LOW
P0966 PRESSURE CONTROL SOLENOID B CONTROL CIRCUIT LOW
P0970 PRESSURE CONTROL SOLENOID C CONTROL CIRCTUT LOW

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....

4400 miles on it. Over last few days the transmission started to slip. First gear engages fine, but the change to 2nd involves a rev....(with no acceleration) till it finally grabs.
Reverse into my garage up my slight incline of a drive does same. Slip rev....slip rev... No gear noises.
Tried to check fluid level...(that's what it sounded like to me) but sealed system.
Taking it in for warranty check/work.

Having my beloved v70 XC SE towed to mechanic today. Suddenly reverse gear was non functioning. No choice. Assume it's time for gear box replacement (whatever that is). Only 133K miles on the vehicle and I LOVE this car. Is it worth the cost to fix transmission or should I just donate or try to sell the vehicle?

I'm having Dodge Neon 2000 manual transmission. Suddenly the reverse gear stopped working (others working). I got it towed to my regular mechanic (used to charge comparatively lower than other local shops) and he said one of the shifter cable is broken and other one is stretched. Need too replace them. Is it worth it? (It's an old car and recently I've been spending a lot on this).

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] .....

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.

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.

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.

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!!!

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?

So my new/old 2004 has another issue. Parked at the grocery store tonight on a very slight incline backwards. Put the Ranger in park (automatic shift) and before I could fully engage the parking brake it began to roll back with a clunk, clunk, clunk as if popping out of gear.
Need less to say I moved to another spot that was more level. Just an hour before I parked the same way on a steeper incline and did not get this. Now I need to watch this carefully until resolved. How to remedy this issue.

Let me first say that my knowledge about vehicles is nearly non existent. Yesterday I was stopped at a light on a hill. When I pulled away up the hill it felt like the tranny was slipping real bad. I coasted into a gas station and stopped. I gave it the once over look around to see if I could see anything unusual. All looked ok, so I wondered if maybe it wasn't all the way into gear or something.
I limped it home only 2 miles and it was seemingly normal although I was real gentle and it was all flat or downhill. Later that night I drove it around the block and it was shuddering and banging and seemed to be slipping again. My question is doesn't the transmission usually go over time, or does it fail suddenly like this. Could it be something else? And lastly what does a rebuild cost. Truck is 06 FX4 54000 miles 3.73 gears. Edge Evolution on level 2.
I tow a Trailer a few times a year 7000 lbs fully loaded, if I do need a new tranny should I replace to a different gear.

2005 F-150 5.4L RWD
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.

I just got a 2004 F-150 XLT. 200k miles AT. The problem is that it won't start. The previous owner was driving it when it suddenly died and wouldn't crank over. He was told by an auto shop it neded a new engine.
I don't think it needs a new engine because it stopped while driving. I may be wrong. I put a new battery in it. When I turn the key to start it, it just makes one loud click and doesn't do anything else. The oil and coolant look fine. What may be wrong with it or how to see if the engine is bad?
