Code p0700 what is the cause.

Automatic transaxle fault code P0700 is a code that indicates that the transmission control module (TCM) has requested the powertrain control module (PCM) to turn on the check engine light to alert the driver that a problem has occurred in the automatic transmission. You now need to have the TCM scanned for fault codes to see what is going on and why the check engine light was requested. Reading the TCM codes requires a special scanner that all dealers have as well as transmission repair shops..

My 2009 Hyundai Sonata quit accelerating while driving in town. The ESC and check engine light came on. I was able to turn the car off and back on and the ESC light went off and acceleration worked...

This may not be your problem but it does bring the vehicle in fail safe you may have a warranty
Number 09-AT-016
Date AUGUST, 2009


An improperly functioning input speed sensor or output speed sensor may result in the following conditions:
^ "Check Engine" light on
^ Harsh P-R or P-D engagement shock
^ Transaxle in 3rd gear fail-safe
^ Diagnostic trouble codes 1. Using a GDS, check for DTCs in both the "Engine" and "Automatic Transaxle" menus. Record the DTC and description.
2. From the GDS, select:
^ Vehicle
^ "Auto Transaxle" menu
^ "Current Data"
^ "Input speed sensor" and "output speed sensor". Drive the vehicle and monitor the input and output speed sensors. If the sensors show:
^ Continuous output, the wiring currently has no open/shorts. Go to Step 6.
^ No output, go to Step 3
3. Check the wiring harness visually for an open circuit or short circuit to ground. Check for a pinched harness at the PCM/TCM attachment bolts.
4. Disconnect the connectors at the input and output speed sensor and PCM/TCM. Check for bent pins or pins not fully inserted into the connector.
5. If a harness open/short is found, repair or replace the ECM control harness between the PCM/TCM and transaxle and go to Step 8. If not, go to Step 6.

My 2009 chev aveo has a hold button. the hold light on the dash is flashing. the book says take it in to fix. what can it be?

I have a 2009 Chevy Aveo. The hold light has come on two times since I have owned the vehicle. The first time at about 37,000 (just out of warranty)the vehicle started running very poorly. the check engine light came on as well as the hold light blinking. At first I thought it was a transmission problem, It was NOT. The problem with this gem of a car is that the spark plugs need to be replaced by 35,000 miles. The check engine light was due to the ignition coil pack being bad (cylinder 3) All four need to be replaced at once. After replacing the coil pack and plugs the check engine light went out and the hold light went out. This was an extremely easy repair. I walked my 13 year old daughter through the repair.

The second time the hold light went on was about a week ago. I now have about 52,000 miles. The light came on for no apparent reason. The only unusual thing that happened was that i accidentally spun the tires in the rain just before the light came on. The owners manual will tell you to bring it in asap because there could be serious problems. I couldn't believe i was having another major problem (there was no check engine light on this time) My guess was that the spinning of the tires could have had something to do with causing the hold light to go on and blink. What i did was disconnect the battery over night in an attempt to reset the light. It worked, i have not seen the light come back on in over a week. I drive about 50 miles a day on the highway as well as stop and go traffic. Ill call that a win.

These lights come on for a reason, if the light comes back on i will be planning on taking it in to a transmission specialist. I am not trying to say you should ignore your lights but sometimes a little effort before taking it into your mechanic can save you a bunch of money. I just wanted to share what i did with you all. Also you can have your check engine codes read my many auto part stores usually at no charge.

I would never buy another Aveo or recommend one to anyone. In my opinion they are poorly manufactured vehicles. I guess i should have guessed that any vehicle with a 3 year 36k mile warranty has such a short warranty for a reason! I hope i could help someone with my experience.

Error P0700. What is the cause? How to repair it?

P0700 JEEP - Transaxle Control System Malfunction
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.

- Engine Light ON (or Service Engine Soon Warning Light)
- Driveability problems
- Transaxle shifting problems

Possible causes
- Shorted or open circuit within transmission control module (TCM)
- Failure of transaxle control module

Tech notes: Since the P0700 is just and informative code, check the TCM for more codes to resolve the problem. So you'll have to have the dealer or another qualified shop/technician pull the transaxle codes from the TCM and go from there.

Good luck (remember to rate this answer)

Where is the dipstick to check the transmission fluid?

LEVEL CHECK Check the automatic transaxle fluid level at least every 15,000 miles or 12 months. The dipstick can be found on the left (driver) side of the engine compartment. The fluid level should be checked only when the transaxle is hot (normal operating temperature). The transaxle is considered hot after about 20 miles of highway driving.
  1. Start the engine, set the parking brake, and put the transaxle selector lever in the P position.
  2. Move the selector lever through all the positions and return to the PARK position. DO NOT TURN OFF THE ENGINE DURING THE FLUID LEVEL CHECK.
  3. Remove the dipstick, wipe it clean and then reinsert it firmly. Be sure that it has been pushed all the way in. Remove the dipstick again and check the fluid level while holding it horizontally. With the engine running, the fluid level should be in the cross-hatched area.
  4. If the fluid level is below the crosshatched area (engine hot), add MERCON® III automatic transaxle fluid through the dipstick tube. This is easily done with the aid of a funnel. Check the level often as you are filling the transaxle. Be extremely careful not to overfill it. Overfilling will cause slippage, seal damage and overheating. Approximately 1 pint of ATF will raise the fluid level into the cross-hatched area. The fluid on the dipstick should always be a bright red color. If it is discolored (brown or black), or smells burnt, serious transaxle troubles, probably due to overheating, should be suspected. A qualified technician should inspect the transaxle to determine the cause of the burnt fluid. Fig. 1: Automatic Transmission dipstick location - Continentals 93141p13.jpg
    Fig. 2: The dipstick is easy to read and well marked. Do not add if level is in the crosshatch area 93141p12.jpg

AT Warning light and Check engine light both turned on

Unfortunately Mazda didn't have the best transaxles out there. First you have to find out what the code is. If the shift solenoid acts up, it will turn the "check engine" light on and well as the AT light. Take it to a shop that is able to scan the codes and let you know what it is. If it's a shift solenoid code, in which that's what I'm expecting, check all the connections to the trans. at the plugs. Look for any frayed wires, burnt or dirty plugs, and any pins that may have lost contact with the sensors on the trans. If all of them look good, take it to a trans. shop for further tests.
