What you need is a "revolution sensor" I had the same exact problem. Replaced the sensor and everything is fine

Transmission model is AX4N.The reason that the car/trans only acts up after long drives is the heat.As metal components heat up,tolerances and clearances that were marginal or borderline before with moderate heat,become excessive clearances when really hot.More than likely there are internal transmission components with excessive wear.Many problematic areas inside the AX4N trans is the pump,where the oil pump driveshaft bearing wears out,the seal is torn,and hydraulic pressure falls off,common failure point in these units.The other areas are typical to all automatic transmissions,the clutch packs and bands wear and lose well as some of the bushings inside the unit.I just rebuilt recently a trans exactly identical to your car,V8...4.6Ltr Lincoln,and it had minimal damage inside,but enough to throw the check engine light on with a Torque Convertor Clutch trouble code.The TCC was slipping excessively,and the vehicle computer recognized this,and illuminated the CEL.Chances are good that the damage inside your trans will be minimal,but now is the time to consider rebuilding it and restoring all the hydraulic circuits integrity,and resetting all the clutch pack and band clearances with new clutches,steels,and bands.A remanufactured torque convertor should also be installed along with rebuilding the trans.Be careful as to who does the work on the trans should you decide to rebuild it,as some people's definition of a rebuild doesn't quite qualify as anything more than a patch/repair job.A complete rebuild consists of tearing the trans completely down,loading it into a parts cleaner,and thoroughly cleaning it.From this point,the rebuild begins,including a banner overhaul kit,new steels,bands,seals,thrust washers as required,Electronic Pressure Control solenoid,all new bushings,set clutch pack clearances to factory specifications,along with setting unit endplay,and a remanufactured torque convertor.Good luck.

I had the same thing! It was a computer issue. It only cost me about $35.00.

SOURCE: p0740 code on 2000 Honda Odyssey

Code p0740 is a problem in lock up control solenoid assembly, Check whether scan tool indicates another code. Does the scan tool indicate another code? YES - Perform the Troubleshooting Flowchart for the indicated Code(s). Do not continue with this troubleshooting until the causes of any other DTCs have been corrected. Measure the line pressure. Is the line pressure within the service limit? Repair the hydraulic system as necessary. Replace the Lock-up Control Solenoid Assembly set lock-up control solenoid valve/shift control solenoid valve A assembly and the A/T clutch pressure control solenoid valve A/B assembly. Turn the ignition switch OFF, and reset the PCM memory by removing the BACK UP fuse in the passenger's under-dash fuse/relay box for more than 10 seconds . Using the scan tool, check to be sure that the engine coolant temperature is 176°F (80°C) or above . Drive the vehicle at 55 mph (88 km/h) for more than one minute . Recheck for code P0740. Does the OBD II scan tool indicate code P0740? YES - Remove the torque converter and inspect for a missing torque converter O-ring. If the O-ring is damaged or missing, replace the transmission and torque converter. NO - The system is OK at this time.

When driving past 20 mph engine sounds like a small jet engine and gets louder when driving on highway

Do this on a deserted straight road. Drive at 25mph and cut the engine. Remember you will have NO brake assist, and NO power steering. Does the noise stop? If is does, it is the engine, if it doesn't, then it is wheel bearings or Transmission noise. You can only check if it transmission on a manual gearbox vehicle by slipping into neutral, or of you can shift into Neutral on an automatic. Make sure you avoid Reverse!

How i fix the p0730 and p0735 in range rover 2006

Possible causes of OBD code P0730
- Low transmission fluid level - Dirty transmission fluid - Shift solenoids - Shift solenoids harness or connectors - Transmission mechanical problems - Transmission hydraulic control circuit The Error code is generally activated on detection of the following conditions: The TCM has detected that the transmission is trying to mechanically shift to a lower gear than intended

Possible causes of OBD code P0735
- Low transmission fluid level - Dirty transmission fluid - Shift solenoids - Transmission mechanical problems - Transmission hydraulic control circuit The Error code is generally activated on detection of the following conditions: P0735 is detected when A/T cannot be shifted to the 5th gear position even if electrical circuit is good.

Hey I have a ford explorer 2006 and it keep saying trans code p0735 what that means ?

code p0735 refers to gear 5 --incorrect ratio.===causes --wiring---TR sensor / switch---shift solenoids--transmission mechanical fault. I would be replacing the TR sensor/ switch first. IF it looks like a transmission mechanical fault Have pressure test done first and check the bands and clutch adjustments before considering a replacement/ over haul. I feel confident it is a electronic fault

Transmission slip mainly at highway speeds

This does not sound good. It is possibly your O/D direct clutch or O/D brake slipping in the transmission. Seek a couple of specialist opinions.

My parents have a 2002 jaguar x type the gearbox fault light has come on for about 2 weeks. Then while driving and not having any problems they were going around a curve at 5-10 miles an hour and the car...

The Gearbox fault light can come on for many reasons and many times you will not feel a problem, this however doesn't mean a fault hasn't occurred, one has, it either is a real problem or a problem caused by one of the many sensors inside the transmission sending an erroneous signal to the control module (TCM) the TCM (transmission control module) determines when to shift based on load and many other factors based on sensor input. In order to determine what fault has occurred you must have the TCM scanned with a special electronic tool, it will read the code and give a preliminary location of the problem part or system.

My 2005 Kia Amanti. While driving at highway speeds, the car suddenly shutters for a second or two as if the transmission is slipping or there is a problem with constant velocity joints if this has them....

If your automatic car is jerking while changing gears, you have a maintenance rather than an operation problem. Check the transmission fluid levels. If that doesn't help, something could wrong with your transmission itself.
First I suggest scanned the PCM and TCM to know if some fault code is stored there. Your mechanic could diagnose the specific problem, and, with this code number we could give you additional tips or details to fixed.

Transmission Component Slipping (TCC Stuck off)

code p 1870 refers to transmission component slipping
That can be from dirty oil or a clutch pack or band slipping or low oil pump pressure in the transmission
you say that it occurs on highway driving after 2 hours and that slipping will add friction heat to the transmission oil bringing on the oil temp light
take it to an accredited transmission professional service center that works on your make of vehicle , have the oil changed which require the pan removal
at the same time that will allow the adjustments to be done
when reassembled and refilled , have a pump pressure test done
