Ford - Explorer :: Hard Jerk While Changing Into 2nd Gear - Error Code P0715
Mar 24, 2015
The other day, my Explorer gave a hard jerk while changing into 2 (maybe 3rd?) gear. Never happened before. I was under 20 MPH & had just stared it. (My speedometer works as do all the dials.) My Check Engine light came on & when I had the code pulled it read quote "P0715."Transmission Speed Sensor circuit condition. Vehicle speed above 15 MPH while transmission output shaft speed below 60 RPM. Possible cause Failed transmission speed sensor or electrical problem"
I got a Transmission Speed Sensor, (which I haven't put in yet), and was told that this would solve the problem. My question is twofold: Is there ANY chance this is a false or misread code and the problem is something else? And could ANOTHER sensor attached to the transmission be the cause? (How many sensors are on the tranny?) All I've read about this problem, say's replacing the Transmission Speed Sensor is preceded by the SPEEDOMETER quitting, but mine works fine.
The truck is a 1997 Explorer 4x4, but I don't use 4x4. In fact I've driven it without the forward drive shaft ever since I had the BW4405 Transfer Case replaced.

2003 Explorer XLT.. All dash lights off finally... had to tape the new ABS connector into the socket on the driver's side. It kept losing signal. Now I am noticing that it is shifting a little hard, definitely not smooth, between 2nd and 3rd. It is not a hard jerk... more like a hesitation. could this be a solenoid? Should I look and feel for additional symptoms? Would it be risky to change out the transmission fluid? or use a cleaning additive?

2004 Sport Trac V6. Been having hard shifting and P0715: Input/Turbine Speed Sensor Circuit. Cleared the codes and still returns.
From my searches, readings and looking at the parts diagram. On the newer 5 speeds the sensor is the one on the inside of the tranny. This requires taking the entire tranny apart? Is there an external connector for the sensor that I can check or clean first? Replace this sensor. I know the older ones were mounted on top of the tranny. I think this one is mounted on the inside though.

My brother's 2005 Santa Fe keeps locking up in 3rd gear. I've read around here that the P0715 error code that I have is for an input sensor, but I replaced that and it still doesn't work. I also tried the vehicle speed sensor as well and it didn't work.
I was with someone at AutoZone who pulled up a page here that said no I really needed to replace the transmission control module but I can't find that thread here.

I have a 2005 hyundia elantra, i just recently noticed mainly while I was driving on the freeway or at higher speeds when I let my foot off the pedal my vehicle would slightly jerk and quickly decrease speed for a second, I then noticed my engine light was on. I stopped at a free computer test auto shop (o' reiley's ) and the test stated trouble code p1505 code definition - idle charge actuator signal - low of coil 1.

its a 99 explorer xlt AWD 5.0l v8. It has the AODE/w tranny. When I take off with it (normal accelerating) it shifts fine from 1st to 2nd. But when it is suppose to change into 3rd gear the rpms will keep rising as i give it gas. When I let off the gas it goes into neutral. I plan on changing the fluid and filter in it. But need to know if there is anything to check in the valve body before putting new fluid back in? This problem has come at a bad time for me.

1997 Chevrolet Silverado 4x4 z71 transmission problems. 5 months ago I had it serviced and A/B shift solenoids changed along with filter and fluid. Now check engine is back on with P1860 code truck also has started shifting more firmly into second and at 65mph it gives a hard jerk.

I have a 2008 Sports Trac, with a 4.0 SOHC engine ... 165k miles. Last week my check engine (CE) light came on and the code is P0401 ... too little flow on the EGR system. I first tried cleaning the existing valve - but CE light still came on. So I replaced the old EGR valve, cleaned the SS tube from the exhaust manifold back to the EGR valve and the CE light is still on. I have not driven the truck since I replaced with the new valve ... only fired her up in the garage. Is this something that could possibly clear up given a couple of miles?

I just pulled error code B1944 from my 96 Explorer. It says
Crash sensor ground
Ckt 1, High res/open
I found the airbag diagnostic module (in passenger cowl area) and checked for loosed wire, nothing found. Where the loose ground wire is located? I checked under the seat (didn't do a through job, but looked).

I have a '97 XLT, 5.0 and the error code for the O2 sensors has popped up, when checking it shows there isn't voltage for the heater circuits. I see there are 3 different heater circuits, 1ea for the left & right O2 sensors and a common one for the catalytic converter O2 sensors, so I ordered another PCM.

My brother and father just finished with all of the small issues after throwing in both a "new" engine into the vehicle and a transmission..both have around 80K miles (chassis has around 180K). There were some issues with codes after both were installed, but then everything was diagnosed and fixed, vehicles codes were gone and vehicle was able to be registered, afterall.
Anyways, now the car threw a P0715 code and has issues with shifting. It appears that the Santa Fe is stuck in a single gear (appears to be a higher gear). The car won't shift properly, especially noticed at higher speeds in a main road. Using tiptronic does not seem to make a difference. After the car sits and is taken around the neighborhood, it seems to drive fine, until it is taken out into a main road...I'm guessing once it heats up?
So, what should be looked into? A sensor? Is it maybe because this "new" used trans was swapped in and all of the trans fluid was replaced with new fluid? What could the issue be? I guesss the car's been a headache but they're trying to get it finished to avoid any further codes/issues.

My daughters 2000 explorer has a PO172 code, tune it up,Replaced filters plugs & wires and rear O2 sensors that were damaged. Has 65 psi on fuel rail. Can not find any vacuum leaks. Not sure maybe injectors are dirty.
Also I replaced MAF, now it idles, But it's a rough Idle,Gets worse in gear. She say's on cold start up she can smell a whiff of gas ..

My Santa Fe indicated P0715 for input speed sensor problem. I purchased both sensors and based on forum input I removed the air box and battery to access senors. Output speed sensor is easy to see and access. I am having a problem locating the input sensor. I see wires going to a sensor under both the main wiring harness and shift cable. Is that the location of the input sensor? If so how do you move the wiring harness and shift cable to allow access? If not, where is the input speed sensor located? The Santa Fe is 2001 V6 2.7L.

The history: I have a 98 ford explorer 156k miles. V6 automatic AWD w/ 4WD. I recently took it in for a rebuild on the transmission due to 3rd gear slippage. When I picked it up (after business hours) the dashboard lit up like a christmas tree with code lights about 4wd & OD. It drove fine and I needed the vehicle so I took it and called the mechanic the next day. He advised me if they did something wrong they would fix it but he would have to run the codes to know what was going on. He told me if it drove fine it was ok to take my time about coming in. Since it was an hour drive (and time off work) I waited till the following week. They ran the codes and determined that they had forgot to "plug my 4wd in" and it was throwing every code possible for that system. Lol...
The problem: During the week I drove it I noticed a distinct grinding / chunking noise when I punched the gas hard at any speed in any gear. It happens about 85% of the time and is sometimes light noise and sometimes very bad.
I knew previously that I had bad ball joints so I figured it was that issue making a grinding noise based on the truck rocking back when I gassed it hard.
After about 2 weeks of hearing the grinding occasionally, it gets to bothering me so I go get the ball joints fixed. New ball joints and it still grinds... Now Im really worried it the transmission so I go back to the transmission mechanic yesterday (another half day off work and hour drive) and he test drives it. Tells me it is the transfer case going bad. Also tells me it wasnt like that when I picked it up because they 'test drive' every car after the work is complete (but somehow didnt notice the flashing codes on this test drive).
The question:
Is it possible while rebuilding the transmission or installing it, that they damaged the transfer case?
Are these systems connected directly to one another?
Is it possible that my 4WD being unplugged for a week or so of driving could have caused an issue in the transfer case?
Is it possible that if the 4WD was 'unplugged' the AWD may have also been disengaged and as a result caused an issue in the transfer case?
Is it likely that its just normal wear on two closely related systems and I should just suck it up and get it fixed?

This summer my power steering went out. I replaced the steering rack with a remanufactured rack, which failed. I got the replacement rack replaced by the remanufacturer and installed by a different shop. Same problem: SEVERE vibration when turning hard right followed by the PS error code, or just little twitchy motions when driving. I'm having the second shop take a look at it again this monday as I suspect that this is a data processing issue.

Last night while driving, my transmission made a pretty severe clunk, but then appeared to act normal. However, a check engine light came on so I pulled over immediately as I was literally at the entrance to a gas station.
I looked under the vehicle, under the hood, saw nothing leaking, nothing obviously broken etc. So got back in and started the engine, went to shift into reverse and the transmission clunks, same going from N into D.
I limped it home, but while driving noticed that it was not shifting but stuck in one gear.
This morning I scanned for codes and the only one showing is P0770 Shift Solenoid. I searched this forum though and get 0 results on that code, searching Google is also surprisingly vague. I believe (could be wrong though) that I have the 6R60 Transmission, it is a 2008 Explorer with the 4.6L V8.
Where to check first? When I get time I am going to check the fluid level, but could not last night as there is no dipstick!

I inherited this car from my grandmother when she passed. It has low miles, around 40k. Since I paid zero for it, I would like to keep it. Historically I have done all my repairs, but never trans work.
Here are the symptoms. The car has issues shifting into higher gears. I have to punch the gas and then it will switch gears. It then began to do this for reverse, and now now reverse does not work at all.
At first I thought it was a speed sensor problem, but when I took it in to be read, it came up with P0734. It could be electrical (Speed sensor?), low fluid (it's not low), or 4th gear.
Is this transmission worth me fixing or paying to have it repaired, or should I move on?
P.S. If I drop the pan and find shavings, I understand that to point to 4th gear and bearing (also what the computer code read as the issue). Do shavings mean it definitely is 4th/bearing, or could it be another blown part?

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

Damn car is stuck in 3rd gear! Hooked up scanner and the screen just says error! I have to keep the scanner in the vehicle, hooked up, just to drive the car. That's just so it'll shift as its supposed to! Now it's not letting me pull the code out, in order for me to erase it! It just keeps saying "error".
