Check your cap and rotor button on the distributor and check you plugs and wires also to make shure nothing is cracked or burnt out.

SOURCE: 46RH transmission, no second gear.

Does it shift into 3rd at the right speed? If 2nd is just missing, try adjusting the kickdown band. (front band). The adjustment screw is on the outside of the case.

I am far from a trans. specialist but this sounds like a foreign body (dirt maybe) got in the valve body.

Can the input speed sensor on a 2009 GMC Acadia be changed without having to remove the transmission

Did you do the diagnostic's that go to that code ?
DTC P0717: Input Speed Sensor Circuit Low Voltage
Diagnostic Fault Information

Open/High Resistance
Short to Voltage
Signal Performance
Input Speed Sensor Supply Voltage
Input Speed Sensor Signal
P0716, P0717
P0716, P0717
P0716, P0717
Circuit/System Description
The input speed sensor (ISS) is a hall-effect type sensor. The sensor faces the 1-2-3-4 and 3-5-R clutch housing machined teeth surface. The sensor receives 8.3-9.3 volts on the input/output speed sensor (ISS/OSS) supply voltage circuit from the transmission control module (TCM). As the 1-2-3-4 and 3-5-R clutch housing rotates, the sensor produces a signal frequency based on the machined surface of the 1-2-3-4 and 3-5-R clutch housing. This signal is transmitted through the ISS signal circuit to the control solenoid (w/body and TCM) valve assembly. The control solenoid (w/body and TCM) valve assembly uses the ISS signal to determine line pressure, transmission shift patterns, torque converter clutch (TCC) slip speed and gear ratio.

Circuit/System Verification
Engine idling, observe the scan tool Transmission ISS parameter while varying the engine speed. The Transmission ISS parameter should change with the engine speed and not drop out.
Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.

Ignition OFF, remove the control valve body cover. Refer to Control Valve Body Cover Replacement.
Connect the TCM harness connector.
Disconnect the input speed sensor (ISS) from the control solenoid (w/body and TCM) valve assembly.
Connect the J 38522 between the supply voltage terminal B and ISS signal terminal A at the control solenoid (w/body and TCM) valve assembly. Refer to Control Solenoid Valve and Transmission Control Module Assembly Input Shaft Speed/Output Shaft Speed Input Test for further instructions.
Set the J 38522 signal to 8 volts, the frequency to 120 and the percent duty cycle to 50.
Ignition ON, observe the scan tool Transmission ISS parameter. The scan tool Transmission ISS parameter should be between 100-400 RPM.
? If not within the specified range, replace the control solenoid (w/body and TCM) valve assembly.
If all circuits test normal, test or replace the input speed sensor.

Control Valve Body Cover Replacement

Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection.
Remove the air cleaner assembly. Refer to Air Cleaner Assembly Replacement.
Remove the oil cooler inlet hose (1) from the retainer on the control valve body cover.
Remove the oil cooler outlet hose retainer nut (5) from the control valve body cover.
Remove the oil cooler outlet hose (4) from the retainer on the control valve body cover.
Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.
Remove the left engine splash shield. Refer to Engine Splash Shield Replacement.
Drain the transmission. Refer to Transmission Fluid Replacement.

you don't need to pull thr trans .

P1111 code on Nissan TIIDA 2007 Sedan was Diagnosed loosing power when driving.I was told about changing oil and cleaning the Intake Selonade valve.How do i clean it.

Try changing oil first. Intake Valve Timing Control solenoid is located on passenger side of engine bay, with an electrical connection on one end. It's held in by one 10mm bolt. It is inside the cover that goes over the camshaft pulleys. Don't use any oil additives, they can gum up the solenoid as it uses oil pressure to adjust your valve timing. If you remove solenoid, it can be cleaned with throttle body cleaner.

Where is transmission range sensor for 99 plymouth?

The TRS is a speed sensor located in the valved body, attached to the transaxle. It has a connector on one side, and the other side is a bolt holding it to the transaxle, and a rod plugged into the valve body. The transmission range sensor is located within the transaxle.To replace it or to check if the part fits you need to take apart the oil pan and valve body.

Here summary procedure:

Take off the battery negative cable.
Bleed oil.
Remove air cleaner assembly.
Put lever in first gear.
Disconnect the gear shift cable from lever.
Remove the manual valve lever from the shaft.
Disconnect the cable from TRS connector.
Raise vehicle on hoist.
Remove all the transmission oil pan bolts
Take off the transmission oil pan .
Remove the transmission oil filter
Undo the valve body-to-transaxle case bolts.
Remove the park rods from the guide bracket and pull off the valve body from transaxle.
Put the valve body on a work bench
Undo the t-25 torx screw holding the TRS.
Do operations in reverse order, when refitting torque the valve body bolts to 105 in lbs.

I hope this helps you,Ken.

Can the idle air control be tested

Idle Air Control Valve



The Idle Air Control (IAC) valve adjusts the engine idle speed. The valve is located on the side of the throttle body. The valve is controlled by a duty cycle signal from the PCM and allows air to bypass the throttle plate in order to maintain the proper idle speed.
Do not attempt to clean the IAC valve. Carburetor tune-up cleaners or any type of solvent cleaners will damage the internal components of the valve.


See Figure 1

0900c152801e4967.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 1: The IAC can be monitored with an appropriate and Data-stream capable scan tool

  1. Turn the ignition switch to the OFF position.
  2. Disconnect the wiring harness from the IAC valve.
  3. Measure the resistance between the terminals of the valve.

Due to the diode in the solenoid, place the ohmmeter positive lead on the VPWR terminal and the negative lead on the ISC terminal.
  1. Resistance should be 6-13 ohms.
  2. If resistance is not within specification, the valve may be faulty.


  1. Disconnect the negative battery cable.
  2. Detach the IAC solenoid connector.
  3. Remove the 2 retaining bolts and remove the IAC solenoid and gasket from the throttle body.
  4. Installation is the reverse of the removal procedure. Use a new gasket and tighten the retaining bolts to 71-97 inch lbs. (8-11 Nm).

If scraping is necessary to remove old gasket material, be careful not to damage the IAC solenoid or the throttle body gasket surfaces or drop material into the throttle body.
See Figure 2

I was wondering where the pressure control solenoid for my ford explorer was located.. Code P0775

Hi there,

Code P0775 = Pressure Solenoid "B"

This solenoid is responsible for feeding the correct transmision fluid 'pressure' through the valve body. The valve body is located inside your transmission and contains multiple valves & shifting solenoids, responsible for the correct shifting behaviour of your gears etc.

To gain access to the valve body/sole, you will need to drain transmission fluid, then undo the transmission cover.

You will need to check the resistance of each solenoid, to confirm they are within factory spec.

Some transmission designs will provide access to the solenoids once you remove the trans cover (this design allows you to easily test/replace the solenoids), but if your design requires the removal of the valve body first, then you should leave this job to an experienced FORD transmission specialist, as the valve body is a very delicate piece of machinery with many minute parts. The valve body can be very easily damaged, if not treated with care.

Good luck....
