Question about 2002 Pontiac Grand Prix

2006 GTO manual transmission will not shift into any gear with engine running...diagnostic scan shows no trouble codes

After the dealer replaced a faulty ignition coil & wire on no. 6 cylinder, the transmission cannot be shifted into any gear with the engine running. It can be shifted into all gears when the engine is not running. No trouble codes are showing on the diagnostic scan, according to the dealer. Could a blown fuse cause the problem without showing a trouble code? What about a bad skip shift solenoid or shift lock solenoid or clutch position switch?

Check the fluid level on your clutch slave cylinder. Have someone depress the clutch while visually observing the movement of the levers under the hood. Could also be a bad throwout bearing.

This is most likely due to a bad solenoid pack in transmission. You could have tranny serviced and see if it helps. Poor fluid condition makes valves stick in those.

Does the clutch pedal engage? This sounds like a clutch problem to me.

I have a ford focus 2008 sedan automatic. I get a transmission malfunction message.

Diagnostic Procedure Before Repair
Step 1 - Clear all DTC's with a engine scan tool (diagnostic trouble codes.) Visit - Scan PCM
Step 2 - Start the engine and observe the MIL, if it does not illuminate continue to next step (service engine soon or check engine light.)
Step 3 - Drive the vehicle while trying to maintain a constant throttle position as it accelerates up through all four gears. If the transmission is shifting properly, it should be in 4th gear by the time you reach 45 to 50 mph on level ground. Repeat this procedure from a standing start 3 to 5 times. Rescan the PCM for trouble codes, if none appear the problem could have been a onetime occurrence. If a trouble code has returned repair as needed and recheck system. Hope This Helps !!!

2002 ford f150 4.6 motor when I drive it will not shift gears on its own it will shift if I manually do it my self I have no idea what's going here

Diagnostic starting point .
SECTION 307-01B: Automatic Transmission - 4R70W 2002 F-150 Workshop Manual DIAGNOSIS AND TESTING Procedure revision date: 06/20/2001 Diagnostic Strategy Troubleshooting an electronically controlled automatic transmission 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.
NOTE: Do not take any 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 have the following publications available:
  • Transmission Reference Manual.
  • Powertrain Control/Emissions Diagnosis (PC/ED) manual.
  • TSBs and OASIS Messages.
  • Wiring Diagram.
These publications provide the information required when diagnosing transmission concerns.
Use the Diagnostic Flow Chart as a guide and follow the steps as indicated.
Preliminary Inspection
  • Know and understand the customer's concern.
  • Verify the concern by operating the vehicle.
  • Check the fluid levels and condition.
  • Check for non-factory add-on items.
  • Check shift linkages for proper adjustment.
  • Check TSBs and OASIS messages regarding the concern.
  • Carry out on-board diagnostic procedures key on engine off (KOEO) and key on engine running (KOER).
  • Record all diagnostic trouble codes (DTCs).
  • Repair all non-transmission codes first.
  • Repair all transmission codes second.
  • Erase all continuous codes and attempt to repeat them.
  • Repair all continuous codes.
  • If only pass codes are obtained, refer to Diagnosis By Symptom for further information and diagnosis.
Follow the diagnostic sequence to diagnose and repair the concern the first time.
It's best if you take your vehicle to a qualified repair shop if your not familiar with any of thing's listed above .Need a scan tool to check for DTC'S .

I have a trouble codes p0717 and p0700 on a 2006 Cadillac cts 3.6 the car shifts crazy and while pushing on the brake it locks up anyone know what's going on please help

P0717 is for the transmission input speed sensor , which inturn will bring up the other code P0700 for the Trans Control Module , so i would suggest having the codes cleared and see if they come back as sometimes a glitch can occour , if codes reappear and so do the symptoms i would replace the input speed sensor , it reads the primary pulley speed and sends info to the TCM and as far as i know there are no diagnostic s to carry out as this sensor either works properly or fails so get it changed and hope its not the TCM as well, keep me posted if you wish

Both error codes you have are transmission related. P0736 is an error for reverse has wrong gear ratio. P0700 is a general transmission problem code

2006 BMW 750 Li My dynamic drive inactive light came on, then a generator fault light came on

BMW has been using electronically controlled automatic transmissions in most models since the late 80s. These transmission systems employ a transmission control unit which controls electrical solenoids to manipulate the various control and shift valves and functions in the transmission valve body. When the transmission control unit detects a problem that it thinks could be damaging to the transmission or engine, it goes into a fail-safe or limp mode. In this mode, the transmission will function in reverse normally, but in forward it will operate in only one gear (whether you have the shifter in D, or any of the lower gears). This will typically be 3rd or 4th gear, depending on the model. It will start in this gear and stay in this gear with no shifting. You would experience this as sluggish acceleration and higher than normal engine speed at about 40 mph and above.

If you must drive the vehicle when the transmission is in the fail safe mode, accelerate gently and keep the road speed lower than full highway speed.

Earlier models do not employ fault codes and must be diagnosed manually. Late models do employ fault codes and a diagnostic/scan machine can be used to check and read the faults to assist in diagnostics. Note that this is not your common OBDII engine management fault code tool. This is what A BMW dealer or a properly equipped independent shop would have for full vehicle system diagnostics and coding operations.

Ford trauras trouble code 732 - was told transmission code 732 was being produced, what does a code 732 say?

P0732 FORD - Incorrect Second Gear Ratio
Transmission in second gear and the ECM detected an incorrect gear ration. This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by Transmission Control Module (TCM) as follows:

Torque converter slip ratio = A x C/B

A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from Engine Control Module (ECM)
C: Gear ratio determined as gear position which TCM supposes

If the actual gear position is higher than the position (2nd) supposed by TCM, the slip ratio will be more than normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.

- Engine Light ON (or Service Engine Soon Warning Light)
- Incorrect transmission shifting

Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

Tech notes
Start by inspecting the transmission fluid level and condition, and change fluid if necessary.

Hope helps.

Was your issue the range selector switch (a.k.a. range sensor, prindle switch, park/neutral safety switch). Part # 37720-86z01?

It is located on the outside of the transmission on the front side (not between the transmission and the firewall). You can open the hood and put an eye on it.

Be VERY sure to alignment it properly AND to clear the code.

If this helps, please say so!

Electronic Transmission Error Indicator
The vehicle is equipped with a redundant electronic gearshift indicator. This character appears with the key in the RUN position and displays the same gear selection as shown on the selector lever floor console next to the range selector lever. If an "E" character flashes or remains on this indicates that a transmission malfunction has occurred.

Auto Transmission

Try shifting the trans manually through the gears and see what happens,doesnt cost anything so,possibility valves are sticking in the valvebody after sitting so long,and manually shifting the car will force some of them to stroke in their bores unless REALLY stuck.Could also be shift solenoids.Scan for diagnostic trouble codes.A bad solenoid will have set a trouble code.Just FYI,1991 was the first year Ford went to all electronic trans,i had a 91 Sable.
