Sounds like you have lost the transmission. There are bands that clamp down to lock the transmission into the gear you want. They are controlled by a hydrolic unit located in the trans. The first thing I would do is have a shop pull the trans oil pan and see if it is full of chips of metal. If so you definately have a problem. At the same time they can look at the bands and see if one of them is broken. another cause would be that metal has gotten into the hydrolic valve body and frozen the drive band portion so it will not function. You may also get lucky and have it be an internal adjustment of the drive band. Good Luck, RAC

the tcm may be faulty or has a loose ground, try swaping in another if you can get one borrowed or a cheap used one from a salvage unit

This sounds as if the input and output speed sensors may be having an issue. If you are putting a used tcm in it will have been powered down and basically reset to it's defaults.Would completely disconnect the battery and hold the cable ends together this will force a hard reset of the tcm and ecm which will return all adaptives to the factory presets.When started it may run very poorly for a few minutes until it relearns. You then should be able to drive it and it will continue it's adaptive learning curve.

Every time I start my 06 equinox the 10 amp backup fuse blows. When I try to restart the car its no crank no start. When I replace fuse it starts fine again. Why is 10amp backup fuse blowing?


A short circuit in the wiring . Do you you know how to test automotive electrical circuits ?
10 amp backup fuse ?????? back up lights ? Video's on youtube showing how to find an fix a short . Park neutral safety switch
The transaxle control module (TCM) primarily controls shift points and lockup engagement.
The transaxle is controlled by an electronic shift system. The TCM processes input signals. From the information received, the TCM controls the transaxle hydraulic system.
The electronic shift system consists of the following components:
• TCM
• Shift Solenoid (SS1 and SS2)
• Pressure Control Solenoid (PSC)
• Lockup Solenoid
• Input Shaft Speed (ISS) Sensor
• Output Shaft Speed (OSS) Sensor
• Transmission Fluid Temperature (TFT) Sensor
• Park/Neutral Position (PNP) Switch

Have the vehicle checked for DTC'S - diagnostic trouble codes
When the TCM detects an invalid combination of TR switch signals, then DTC P0705 sets. DTC P0705 is a type A DTC.

BACKUP Fuse
10A
PNP Switch



The transmission range (TR) switch is part of the park/neutral position and back-up lamp switch assembly and is mounted on the transmission manual shaft. The TR switch is a multi-signal switch. The transmission control module (TCM) supplies voltage to the TR switch. Each gear selector lever position grounds one or more of the signal circuits in a unique pattern. In order to determine the gear range selected by the driver, the TCM compares the voltage combination on the signal circuits to a TR switch combination table stored in memory. Refer to Transmission Range Switch Logic .

Tip

I get code p0700 after an OBDII scan.


P0700 Transmition Control system is the transmission control module.
The transmission control module is a separate computer module, you need to read codes stored on transmission control module.

If there are no transmission code stored, then there is a bad Transmission Control Module (TCM) ground circuit or a bad TCM. In that case the ground to TCM must be tested, and TCM eventually replaced.

Faults that can cause troubles when shifting from first to second gear are : transmission fluid, speed sensor, TPS, transmission shift solenoid, gear box problem, TCM, neutral switch, torque converter problem.

The best thing to do is scanning TCM codes.

Manual transmission. What are the probable causes of DTC P0851?


code p 0851 refers to park/neutral switch (PNP)--input circuit low===causes ---wiring---short to ground---PNP switch---ECM/TCM
with the manual transmission there may be a pnp switch that prevents an engine start unless it is in neutral and in some scars the foot brake also has to be applied
check /replace the neutral switch and check the wiring and connections for corrosion

What does diagnostic code PO0706 and PO700 mean?


OBD II Fault Code
  • OBD II P0706
Fault Code Definition
  • Transmission Range Sensor Circuit Range/Performance
The purpose of the automatic transmission is to match the engine's optimum power and torque characteristics to the driver's desired rate of acceleration and speed by auto-selecting different gear ratios or 'speeds' to power the wheels. The Transmission Range Sensor (also referred to as the PRNDL input and/or neutral safety switch) tells the transmission control module (TCM) and the powertrain control module (PCM) that the transmission is in park, reverse, neutral, drive, low, 2nd, 3rd etc. It is attached directly to the manual valve of transmission, so when the shift lever is moved say from park to drive, the Transmission Range Sensor communicates this critical information to the above mentioned vehicle computer systems.

P0700
Many vehicles have a control module for the automatic transmission called a transmission control module (TCM). The engine control module (ECM) communicates with the TCM to monitor the automatic transmission for faults. If the TCM detects a fault in the automatic transmission and sets a transmission related fault code, the ECM is informed of this also and sets a P0700 in the ECM memory.

1996 Pathfinder Auto. Wont start. Turn ignition key , all lights on dash, headlights OK, hear a click. Spoke to mechanic who said to hold ignition on whilst moving auto lever. Did this and car eventually...


You need to adjust the park neutral saftey switch. the problem you are having is the truck thinks the it is not in Park so the truck will not start unless it is all the way in park. Take the keu turn half way and move shifter to neutral and see if it starts. Then I cam tell you how to adjust it.

I have a 01 ford taurus whit p0705 transmission code and i have no idea what this mean


Code P0705 - Transmisson Range Sensor Circuit (PRNDL Input)
The transmission range switch detects the selector lever position and sends a signal to the TCM.

The park/neutral position (PNP) switch includes a transmission range switch. The transmission range switch detects the selector lever position when the shift lever is in the N or P shift position and sends a signal to the Transmission Control Module (TCM).

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes
- Open or short park/neutral position switch circuit
- Poor park/neutral position switch circuit connection
- Misadjusted park/neutral position switch
- Park/neutral position switch may be faulty

Keep us updated (remember to rate thsi answer).

THERE MUST BE SOME FAULT CODES STORED IN TCM..WHEN A FAULT OCCURS,THE TCM SHUTS THE POWER FEED OFF TO THE SHIFT SOLENOIDS IN THE SOLENOID PACK SO ALL YOU HAVE IS SECOND GEAR(LIMP MODE)..IS YOUR SPEEDOMETER WORKING?IF NOT IT MAY BE THE OUTPUT SPEED SENSOR IS BAD..YOU SHOULD GET TCM SCANNED FOR FAULT CODES..I HOPE THIS HELPS
