92 240sx automatic transmission shifting problems

My trouble started almost overnight following some routine service (new plugs and brake service). The transmission use to shift smoothly, now it doesn't shift until the engine revs high. Could what you told -hedied4me7- that a vacuum hose from the intake manifold to the transmission modulator valve have something to do with it?

I have the same car too and i would check the fluid level on the tranny while on, located passenger side behind engine(yellow dipstick). Then as someone else had told you to check all vaccum lines. Check for tears of cuts or disconnected. Also maybe the torque converter is bad. I also feel like something internal may have gotten damaged from some unnessesary high reving. Not recommended for never serivced trannys but if you've been on top of ur fluid service get one now and see if that might help. Also is the original tranny and how many miles does it have on it. Age is always a factor.

My 2009 Pontiac G5 started doing this about 3 months ago. On startup, the door locks make noise and it takes a while to shift out of park


Have the vehicle checked for DTC'S diagnostic trouble codes stored in the BCM - body control module . Everything is electroniclly controlled .
Automatic Transmission Shift Lock Control Description and Operation
The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components:
• The automatic transmission shift lock solenoid (serviced as the automatic transmission shift lock actuator), as well as the body control module (BCM) and the engine control module (ECM). The shift lock solenoid is located within the floor shift control assembly with vehicles equipped with floor shift.
• The BCM controls the voltage to the shift lock control solenoid through the shift lock control solenoid controlled voltage circuit. The following conditions must be met before the BCM will remove voltage from the shift lock solenoid:
- The ignition is in the ON position.
- The engine control module (ECM) sends an input via GMLAN serial data to the BCM indicating the transmission is in the PARK position.
- The BCM determines the brake pedal is applied according the brake pedal position.
Since the shift lock control solenoid is permanently grounded, the BCM supplies voltage to the automatic transmission shift lock control solenoid, mechanically locking the shift lever in the PARK position as the solenoid energizes. When the brake pedal is applied, the BCM turns the control voltage output of the shift lock control solenoid OFF, de-energizing the shift lock control solenoid. The de-energized solenoid releases the mechanical lock allowing the driver to move the shift lever out of the PARK position. When the transmission is out of the PARK position, the shift lock control solenoid remains de-energized.
During remote start operation, the BCM will energize the shift lock control circuit, locking the shift lever in the PARK position.

The BCM supplies and monitors a reference voltage to the door lock switch through the door lock switch lock/unlock signal circuit. The door lock switch also receives a constant ground source. If a door lock switch is placed in the lock position, the reference voltage is taken directly to ground and the BCM senses 0.0 volts on the signal circuit. If a door lock switch is placed in the unlock position, the reference voltage is taken to ground through a 15k ohm resister that is internal to the door lock switches and senses approximately 2.9 volts on the signal circuit. This is how the BCM determines what portion of the door lock switch was activated.

Circuit/System Description
The body control module (BCM) controls the shift lock solenoid by providing battery voltage to the shift lock control solenoid. The BCM utilizes a smart driver to control the voltage supplied to the shift lock solenoid. The smart driver monitors the voltage and current flow of the control circuit.
Diagnostic Aids
• Use a scan tool to verify there are no brake pedal position sensor and/or transmission internal mode switch (IMS) DTCs set that could cause the BCM not to provide battery voltage to the A/T shift lock solenoid.
• If the automatic transmission shift lock control circuit is shorted to battery positive voltage, the A/T shift lock solenoid will be inoperative. The vehicle will shift out of PARK without depressing the brake pedal.

Automatic Transmission Shift Lock Control System
The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the ignition is ON. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components:
?€¢
The automatic transmission shift lock control solenoid


?€¢

?€¢
The brake to shift relay


?€¢
The rear integration module (RIM)

With the ignition in the ON position, battery positive voltage is supplied to the brake to shift relay coil. When the RIM energizes the brake to shift relay, the brake to shift relay switch contacts close suppling battery voltage to the automatic transmission shift lock control switch. The circuit continues through the normally --closed switch to the automatic transmission shift lock control solenoid. The permanently grounded solenoid is energized. This locks the shift linkage in the PARK position. When the driver presses the brake pedal, the contacts in the automatic transmission shift lock control switch open. This causes the automatic transmission shift lock control solenoid to release. This allows the shift lever to move from the PARK position.

IMO it's more likely that you have the wrong grade of ATF. It's very important to have the correct grade. The following site shows this:
http://www.nairaland.com/1364064/automatic-gearbox-problems
each car manufacturer has recommended grades of Automatic Transmission Fluid, BMW is no exception. the following website for BMWs may bring you more accurate data:
http://www.nairaland.com/1364064/automatic-gearbox-problems
Apparently CTSC is the supplier for BMWs via the web.
Generally auto gearboxes have drain plugs and filler plugs to enable oil change in routine maintenance. But I would definately go back to the garage where you had the last service and ask politely about the grade of ATF used, before considering an 'oil change'.
Good Luck

04 CTS Ignition Key Stuck, but I can remove the key and restart after a battery disconnect


The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components.
• The automatic transmission shift lock control solenoid
• The brake switch
• The rear integration module (RIM)
• The transmission control module (TCM) or powertrain control module (PCM)
With the ignition ON, battery positive voltage is supplied to the automatic transmission shift lock control solenoid from the ignition 3 relay. The automatic transmission shift lock control solenoid is controlled by the rear integration module. When the rear integration module (RIM) receives a class 2 serial data message from the transmission control module (TCM) or powertrain control module (PCM) indicating that the shift lever is in the PARK position the rear integration module (RIM) grounds the automatic transmission shift lock control solenoid control circuit. This causes the solenoid to energize mechanically locking the shift lever in the PARK position. When the driver presses the brake pedal the rear integration module receives the brake applied signal and turns off the ground to the automatic transmission shift lock control solenoid control circuit. This allows the shift lever to be moved out of the PARK position.
