SOURCE: 97 gmc pickup with automatic transmission trouble

1st thing to do is test the system for codes, the problem is most likely a failed or stuck shift solenoid indside the trans, have you ever serviced the trans, sometimes a fluid and filter cahnge will cure these kinds of issues.

need more info i had a 1984 chevy half ton and first, second, and third worked fine but lock up didnt work. the problem was there was no vacum at a switch under the hood on the fire wall also your shift linkage could be out of adjustment. try driving down the road and raise up a little on the shifter.

your transmission has possibly been rebuilt with stronger springs put in. No worries. have been running mine for along while without any problems. Better this than slipping, but it is a bit annoying.

Check the linkage at the transmission. Have somebody move the selector while you watch the linkage move. It might be out of adjustment for reverse, or be binding up.

06 buick lucerne wonr crank key wont turn to off position shifter stuck in park


Define won't crank ? I'am assuming the key will turn to the start position ! When doing so does the starter spin the engine or not ? Trying to define your problem of won't crank . If when you turn the key to start position an the starter spins the engine over but doesn't start an run , this is a cranks no start condition . If nothing happens when you turn the key to start , this is a no crank no start condition . Your vehicle has a safety system , shift interlock , won't let it shift out of park if the brake pedal isn't pressed . Won't let the key turn off either . Electronics involved , locking solenoid's etc.... Floor or column shift ?
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)/powertrain control module (PCM). The shift lock solenoid is located within the floor shift control assembly with vehicles equipped with floor shift.
• The BCM controls the voltage supply circuit of the shift lock control solenoid. The following conditions must be before the BCM will supply voltage to the shift lock control solenoid.
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 supply voltage to the shift lock solenoid:
• The ignition is in the ON position.
• The ECM/PCM 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 unlocking the shift lever allowing the driver to move the shift lever out of the PARK position as the solenoid energizes. When the brake pedal is not 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 mechanically locks the shift lever in the PARK position.
During remote start operation, the BCM will de-energize the shift lock control circuit, locking the shift lever in the PARK position.

Plus the reverse lock out !
The reverse lockout system is a safety feature which prevents an inadvertent shift into reverse at speeds above 5 km/h (3 mph). The system consists of the following components:
• The engine control module (ECM)/powertrain control module (PCM)
• The reverse lockout solenoid
With the ignition ON, battery voltage is supplied directly to reverse lockout solenoid. At forward speeds above 5 km/h (3 mph), the ECM/PCM commands the reverse lockout solenoid ON by grounding the control circuit of the solenoid. This energizes the solenoid and mechanically prevents the shift lever from being moved into the REVERSE position. At forward speeds below 5 km/h (3 mph), the ECM/PCM commands the reverse lockout solenoid OFF, de-energizing the solenoid, which allows the shift lever to move into the REVERSE position.

Power Mode Master
This vehicles BCM functions as the power mode master (PMM). The ignition switch is a low current switch with multiple discrete ignition switch signals to the PMM for determination the power mode that will be sent over the serial data circuits to the other modules that need this information, and so the PMM will activate relays and other direct outputs of the PMM as needed. Refer to Power Mode Description and Operation for a complete description of power mode functions.
You have no clue of the electronics in your vehicle , your best bet have it towed to the Buick dealer .

Shifter is locked in park on a 2002 bravada that sayes on dash its in reverse


PRND321 Display
The instrument panel cluster (IPC) displays the selected gear position as determined by the engine control module (ECM). The IPC - instrument panel cluster receives a serial data message from the ECM indicating the gear position. The PRND321 display blanks if:
?€¢
The ECM detects a malfunction in the transmission range switch circuit.


?€¢
The IPC detects a loss of serial data communications with the ECM. 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 automatic transmission shift lock control switch

With the ignition in the ON position, voltage is supplied to automatic transmission shift lock control switch. Voltage flows through the normally closed contacts of the automatic transmission shift lock control switch to the automatic transmission shift lock control solenoid. The automatic transmission shift lock control solenoid is permanently grounded. This energizes the automatic transmission shift lock control solenoid causing the transmission shift lever to be physically locked in the PARK position. When the brake pedal is pressed the contacts in the automatic transmission shift lock control switch open, de-energizing the automatic transmission shift lock control solenoid. This allows the shift lever to be move out of the PARK position.
The transmission range (TR) switch is part of the park/neutral position (PNP) and backup lamp switch assembly, which is externally mounted on the transmission manual shaft. The TR switch contains four internal switches that indicate the transmission gear range selector lever position. The PCM supplies ignition voltage to each switch circuit. As the gear range selector lever is moved, the state of each switch may change, causing the circuit to open or close. An open circuit or switch indicates a high voltage signal. A closed circuit or switch indicates a low voltage signal. The PCM detects the selected gear range by deciphering the combination of the voltage signals. The PCM compares the actual voltage combination of the switch signals to a TR switch combination chart stored in memory.
You need a Tech2 scan tool to diagnose this problem ! possible range sensor !

With 1991 f-150 truck running the auomatic transmission will shift into reverse but notthing else


Rule out the easy stuff first...
Does it have the correct type and amount of fluid in the transmission? There should be a dipstick you can check.
After that, the problem could be with the linkage at the shifter, or the linkage at the transmission, or internal to the unit.

Why do the reverse lights remain lit when the ignition is switched on and the suv is running. This happens in all gears. I removed the center console to look for the reverse light switch, and it seem


You may be looking in the wrong place. It is on the transmission. The switch must be pretty wimpy because it doesn't directly drive the reverse lights, but connects to a reverse light relay in the smart junction box. The relay could be stuck. Unplug the two wire connector at the transmission then turn the key to RUN and see if the reverse lights are still on. If they are on then the relay is stuck and needs to be replaced. If they are not on then the switch in the transmission is bad.

1997 Carolla- engine dies when shift to reverse or drive, starts again when put in park. Is this a transmission problem or starter/ignition problem?


There is a switch that only only allows you to start the engine in Park or Neutral. It sounds as if yours is faulty or has a bad connection. Finding it will be the problem.

Shifter physically won't move into reverse position


To isolate the problem as either an internal transmission problem,or external to the transmission,(shifter or cable malfunction),the shifter cables should be disconnected from the transmission.On the transmission are two levers,if you have a 5 speed trans.One is the neutral gate lever,and the other is actual gear shift lever.Manipulating the levers manually,see if the transmission will engage into Reverse gear.If the transmission engages into Reverse gear,then the problem is either in the shifter mechanism itself,or the shift cables.If the transmission will not engage into Reverse gear,then the problem is either an internal problem,or possibly a switch seized up,like the reverse gear indicator switch.At this point,i would have an assistant sit in the car,engine off,and run through all the gear selections with the shifter,while watching and looking for a cable not operating to its full stroke.Take the console apart to access the shifter mechanism and visually inspect the assembly.Disconnect the cables and operate them manually,one at a time,while an assistant watches them underhood.Visually inspect the shifter and it's mechanism for a broken,cracked,or damaged component.At this point,the problem should be identified and repaired as either cable or shifter malfunction.
