The transaxle control module is a problem, once in a while the car jerks and im getting concerned that it runs a little bit loud and sometimes it feels like its shaking. when i went to autozone the code said that it was the transaxle control module. im scared that my car will break down and i need my car. will my car be ok if i get it fixed? and does it take along time once it put in the shop to get fixed?

Oh boy, this is a simple DIY job. You don;t need fancy tools as long as you are patient and clean. The Torque Converter Solenoid costs $70 at NAPA. The whole job for a novice takes about 2 hours. You'll have to remove the battery and battery plate to get enough room to disconnect the wire connector and remove three small bolts. Before you remove them, clean the entire area with Simple Green and an old toothbrush and wash it off with water. Remove the solenoid and then use a safety razor blade to scrape off any gasket material let on the polished face. Try to get as much off intact as you possibly can. Little bits will fall into the holes, so you'll need a long clear plastic tube to suck the oil up and empty each time from the gasket bits until they are as good as you can get them. Do all the holes! Place the new gasket on the new solenoid with the bolts holding it on and screw them in, reconnect the connector and then reinstall the battery. If you haven't done a ATF service, this is a good time to do it too. Costs $35 in parts and you'll need two oil drain pans to contain the ATF once you break the sump bolts. Scrape the gasket off, clean off the metal filings from the magnet inside and replace it, Simple Green works great inside to! Finally pop the old filter off and press the new one on... make sure the new one has an 'O' ring on it or reuse the old one. Refit the sump with new gasket and refill with 5 qts of Castrol ATF +4. Turn on the the engine and cycle through thr tranny and let the fluid warm up. Turn off the car and chekc the fluid level again and top it up to the warm or hot line on the dip stick. NEVER use anything but ATF+4 in this transmission or you're hosed. Lucas trannie medic Non-Slip is a ***** sentence to this transmission. ATF+4 pours like water... if anything is in there that is thicker, it been monkeyed with.

I know that the PT's, Neon's and Stratus's shake when in gear at a stop. It maybe possible that its time for a tune up aka Spark plugs and Plug wires.

SOURCE: 93 Chrysler Le Baron Dying

I'm not a mechanic, but your story sounded so familiar I thought I would reply. My Dad's 94 Dodge Spirit V6 (same car basically) behaved exactly the same as your LeBaron, to the extent that he was tired of being left stranded and no longer felt comfortable driving the car. The car was otherwise well-maintained and in great shape, so I was frustrated too. After a lot of digging and reading forums on the internet and chatting with a neighborhood mechanic, one suggestion that kept coming up was the pickup coil (Hall Effect sensor) located in the distributor. Apparently this was an occasional problem with these cars, and would not necessarily show up in a diagnostic.I priced one out at a parts store and recall it was a couple hundred bucks...too much for an iffy experiment. But, they were kind enough to print me a picture of it from their parts book. I went to a self-serve auto wrecker and snatched one from the distributor of another car (a 95 Acclaim with the same 3.0 V6). They charged me $5 for it. Anyway, I exchanged it with the one in my Dad's Spirit. That was a couple of years ago, and the car has never given him trouble since. If you are still fighting this problem you could always give this a try.

SOURCE: Trouble codes p0301 and p1684

It seems like P1684 is a com problem with the modules. As far as your cyl. #1 misfire try switching the coil, plug and see if the problem follows to the cyl. you swapped plug and coil with, this will help issolate the cause. Also look for oil accumulation in the plug hole, cracked coil, arcking through the plug boot.

Since yours is a forward engine car. The transaxle must be located in the front.

Where is the Output Shaft Speed Sensor located on a 2004 Mercury Sable Duratec 24-Valve DOHC

Did you have it checked for code's ?
P0720 OSS Insufficient input from OSS sensor. PCM detected a loss of OSS signal during operation. Harsh shifts, and abnormal shift schedule. (MIL on) Will display Check Transmission message. Go To Pinpoint Test G . P0721 OSS Output shaft speed sensor signal noisy. PCM has detected an erratic OSS signal. Harsh shifts, and abnormal shift schedule. Go To Pinpoint Test G . P0722 OSS Output shaft speed sensor signal intermittent. PCM has detected an erratic or no OSS signal. Will display Check Transmission message. Go To Pinpoint Test G . Hooking up a scan tool an checking DTC'S an viewing sensor input data to the computer is the correct way to diagnose , not guess OSS , an just replace parts . Your best bet , take it to a qualified repair shop.
SECTION 307-01: Automatic Transaxle/Transmission - 4F50N 2004 Taurus/Sable Workshop Manual DIAGNOSIS AND TESTING Procedure revision date: 07/02/2003 Transaxle Drive Cycle Test NOTE: Always drive the vehicle in a safe manner according to driving conditions and obey all traffic laws.
After carrying out the Quick Test, use the following Transaxle Drive Cycle Test for checking continuous codes:
NOTE: The Transaxle Drive Cycle Test must be followed exactly. Malfunctions must occur 4 times consecutively for shift error DTC code to be set, and five times consecutively for continuous torque converter clutch code to set.
NOTE: When carrying out the Transaxle Drive Cycle Test, see the solenoid operation chart for correct solenoid operation. Refer to Pinpoint Tests - Non OSC Equipped Vehicles in this section.
  1. Record and then erase Quick Test codes.
  1. Warm engine to normal operating temperature.
  1. Make sure transmission fluid level is correct.
  1. With transaxle in OVERDRIVE, moderately accelerate from stop to 80 km/h (50 mph). This allows the transaxle to shift into 4th gear. Hold speed and throttle opening steady for minimum of 15 seconds.
  1. With transaxle in 4th gear and maintaining steady speed and throttle opening, lightly apply and release brake (to operate stoplamps). Then hold speed and throttle steady for additional 5 seconds minimum.
  1. Brake to a stop and remain stopped for minimum of 20 seconds.
  1. Repeat Steps 4 through 6 at least 5 times.
  1. Carry out Quick Test and record continuous codes.
  • If DTCs are present, refer to Diagnostic Trouble Code (DTC) Charts in this section. Service all non-transaxle DTCs first as they can directly affect the operation of the transaxle. Repeat the Quick Test and Road Test to verify the correction. Erase DTCs, carry out drive cycle, and repeat the Quick Test after completing service on the DTCs.
  • If the continuous test passes (system pass) and a concern is still present, refer to Diagnosis By Symptom in this section check OASIS, and TSBs for diagnostic concern.
After On-Board Diagnostics
NOTE: The vehicle wiring harness, powertrain control module and non-transaxle sensors may affect transaxle operations. Service these concerns first.
After the On-Board Diagnostic procedures are completed, service all DTCs.
Begin with non-transaxle related DTCs, then service any transaxle related DTCs. Refer to the Diagnostic Trouble Code (DTC) Charts for information on Condition and Symptoms. This chart will be helpful in referring to the correct manual(s) and to aid in diagnosing internal transaxle concerns and external non-transaxle inputs. The pinpoint tests are used in diagnosing electrical concerns of the transaxle. Make sure that the vehicle wiring harness and the powertrain control module are diagnosed as well. Refer to the Powertrain Control/Emissions Diagnosis (PC/ED) manual for diagnosing non-transaxle electronic components. The diagnostic routine hydraulic/mechanical charts will help in diagnosing internal transaxle concerns and external non-transaxle inputs.
Before Pinpoint Tests
NOTE: Prior to entering pinpoint tests, check the powertrain control module (PCM) wiring harness for correct connections, bent or broken pins, corrosion, loose wires, correct routing, correct seals and their condition. Check the PCM, sensors and actuators for damage. Refer to the Powertrain Control/Emissions Diagnosis (PC/ED) manual.
NOTE: If a concern still exists after electrical diagnosis has been carried out, refer to Diagnosis By Symptom in this section.
If DTCs appear while carrying out the on-board diagnostics, refer to the Diagnostic Trouble Code (DTC) Charts in this section for the appropriate repair procedure. Prior to entering pinpoint tests, refer to any TSBs and OASIS messages for transaxle concerns.

I have a 1998 lincoln Continental, only 140k miles on her, front wheel drive,we had a storm like 2 months ago hard rain and thats when it started this. But when you go from park to reverse it doesnt go...

I wouldn't think transmission mechnical problem seeing how it's not shifting correctly . I would think electronic problem seeing how this trans has electronic shift control . Could be a wiring harness issue or shift solenoid , input data to the control module .
Diagnostic Strategy Troubleshooting an electronically controlled automatic transaxle is simplified by using the proven method of diagnosis. One of the most important things to remember is that there is a definite procedure to follow. DO NOT TAKE SHORT CUTS OR ASSUME THAT CRITICAL CHECKS OR ADJUSTMENTS HAVE ALREADY BEEN MADE. Follow the procedures as written to avoid missing critical components or steps.
To properly diagnose a concern, the technician should have the following publications available:
  • transaxle reference manual
  • Powertrain Control/Emissions Diagnosis Manual
  • OASIS messages
  • technical service bulletins (TSBs)
  • Electrical and Vacuum Troubleshooting Manual
Refer to the Electrical and Vacuum Troubleshooting Manual for the wire schematic and connector numbers cited in the pinpoint tests.
These publications provide the information required when diagnosing transaxle concerns.
Using the Diagnostic Flow Chart as a guide, follow the steps as indicated.

Preliminary Inspection
  • Know and understand the customer's concern.
  • Verify the concern by operating the vehicle.
  • Check fluid level and condition.
  • Check for NON-factory add-on items.
  • Check shift linkages for proper adjustment.
  • Check TSBs and OASIS messages for the concern.
Diagnostics
  • Perform on-board diagnostic procedures (KOEO, KOER).
  • Record all diagnostic trouble codes (DTCs).
  • Repair all NON-transaxle codes FIRST.
  • Repair all transaxle codes SECOND.
  • Erase all CONTINUOUS codes and attempt to repeat them.
  • Repair all continuous codes.
  • If ONLY PASS codes, proceed to Diagnosis by Symptom Chart for further information and diagnosis.
By following the diagnostic sequence, the service technician will be able to diagnose and repair the concern the first time.

Your best bet , take it to a qualified repair shop.

Why does my car jerk really bad when shifting from park to drive? sometimes while im driving it also does the same thing

Transaxle is most likely worn out & due to
be rebuilt

The hard shifting could be an electrical control problem

When you drive any vehicle, even 10 miles ,with any trans
problems, you basically ruin it & do so quickly

What happens is no one changes the fluid every 3 years

It breaks down from the heat & so goes the trans

Then thinking a fluid change will help & it won't do a thing
after years of neglect,the fluid is changed & nothing gets better
& sometimes the trans starts to slip.

What you need to do is have a trans or repair shop check for codes
& road test with you along & driving, to explain the issues

Not changing the fluid causes microscopic particles that normally
occur in side a trans as it wears the clutch material & bushings, to
become lodged in the solenoids

Finding the bad solenoid & even getting to them on a transaxle
verse a rear drive vehicle, is a problem & since your driving it
with the slamming & such from delayed shifts ,your pretty much done.

2004 vehicle is 11 years old & about 150,000 miles

Pull it & rebuild it or install a reman

If it were a rear drive such as my 2004 lincoln ,I would say
pull the pan & change the solenoid pack,not so on yours

Dtc 0700 jerks when shifting from reverse to drive

The transaxle Control Module (TCM) monitors the malfunction of sensors and actuators relating to transaxle control. When the TCM detects a malfunction with the control, a signal is send to the Engine Control Module (ECM) to trigger the Engine Light or Service Engine Soon light. The ECM stores the P0700 code and it means the TCM detected a malfunction with the transaxle controls.

My 2000 caravan jerks to the right when it shifts

I would have the transaxle mount on the driver side engine compartment checked. One way to get an idea if it may be shot is to start engine, apply park brake, put transaxle in reverse and with one foot on main brake pedal and other on gas give the gas a quick tap and see if you hear a loud thump which will be the transaxle flexing the trans mount. If the rubber insulator is shot then you'll hear it.
