Question about 2000 GMC Safari

Open Question

The gear shift indicator light in the instrument cluster shows that the transmission is in 3rd gear at all times once the ignition switch is turned to the on/start position even when the transmission is actually in park or any other gear position. The transmission works as it should do when driving and shifts up and down the range as normal but the light on the cluster never moves from the 3rd gear position. I have changed the park/neutral switch but this did not fix the problem.

Sounds like you have a bad shift solenoid. Not sure if the Chevys are a solenoid pack, or seperate, but it will need to be replaced.

SOURCE: instrument cluster inoperative, transmission shifting problems

These vans have had issues with the PIN connections to the instrument clusters. With time the solder on the main PIN connection will begin to fail. The good news this may be repaired at home. First you'll need to remove the instruments. To do so remove the dash components from around the instruments then the (4) screws) that hold the instruments in place. Carefully detach the wire connection from the back of it; take to a well lit area. Look for a PIN with a failed solder joint (this will appear as a slight black or grey circle. If found apply heat and let solder begin to flow; the allow to cool and reassemble. If you look at my history you'll see I've helped others with this issue. The attached link may help: http://dodgeforum.com/forum/dodge-caravan/197192-99-grand-caravan-intermittent-dead-dashboard.html

As for the transmission I expect this a seperate issue, possibly the BCM but I'd like to review further.
Please let me know if this assisted you,
Tom

SOURCE: E40d trans will not shift into 3rd or 4th gear, only rev. 1+2

check or replace your thottle position sensor tps that trans needs to know where the throttle is to shift if it is bad it will do as you say wont shift to third
another telltale is it will act like it goes into lockup when shifting into reverse and stall the engine

The esp bas light is on my 2009 dodge 1500 and it won't start


An Electronic Stability Program (ESP)/Brake Assist System (BAS) indicator is standard equipment on all instrument clusters. The ESP/BAS indicator is serviced as a unit with the instrument cluster.
The ESP/BAS indicator gives an indication to the vehicle operator when the Electronic Stability Program (ESP)/Brake Assist System (BAS) has been activated. This indicator is controlled by a transistor on the instrument cluster circuit board based upon cluster programming and electronic messages received by the cluster from the Controller Antilock Brake (CAB) and the Transmission Control Module (TCM) over the Controller Area Network (CAN) data bus.
The ESP/BAS indicator Light Emitting Diode (LED) is completely controlled by the instrument cluster logic circuit, and that logic will only allow this indicator to operate when the instrument cluster receives a battery current input on the fused ignition switch output (run-start) circuit. Therefore, the LED will always be OFF when the ignition switch is in any position except ON or START. The LED only illuminates when it is provided a path to ground by the instrument cluster transistor. The instrument cluster will turn ON the ESP/BAS indicator for the following reasons:
  1. Bulb Test- Each time the ignition switch is turned to the ON position the ESP/BAS indicator is illuminated for about four seconds as a bulb test.
  2. ESP/BAS Indicator Lamp-On Message- Each time the cluster receives an electronic ESP/BAS indicator lamp-ON message from the CAB indicating that the ESP/BAS system has been activated, the ESP/BAS indicator will be illuminated. The indicator remains illuminated until the cluster receives a lamp-OFF message from the CAB, or until the ignition switch is turned to the OFF position, whichever occurs first.
  3. ESP Full Off Textual Message- Each time the cluster receives an electronic ESP Full OFF indicator lamp-ON message from the CAB indicating that the ESP/BAS system has been manually disabled, an ESP OFF textual message will appear within the cluster odometer display. The ESP OFF textual message remains displayed until the cluster receives a lamp-OFF message from the CAB, or until the ignition switch is turned to the OFF position, whichever occurs first.
  4. Actuator Test- Each time the cluster is put through the actuator test, the ESP/BAS indicator will be turned ON, then OFF again during the bulb check portion of the test to confirm the functionality of the LED and the cluster control circuitry.
The CAB continually monitors the ESP/BAS circuits and sensors to decide whether the system is in good operating condition and the proper outputs to the components of the system. The CAB then sends the proper lamp-ON or lamp-OFF message to the Electro Mechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN).
For proper diagnosis of the ESP/BAS system, the CAB, the TCM, the EMIC, the CAN data bus or the electronic communication related to the ESP/BAS indicator operation a diagnostic scan tool is required. Refer to the appropriate diagnostic information.

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 !

Gear shifting panel light


I am assuming that your shift lever is on the steering column. Either the bulb for indicator has burned out or the shift indicator switch on the transmission has failed. There are 3 different engine options for this truck and 3 different transmissions. I would need to know which engine and transmission your truck has, to give better info. FYI, you have to remove the instrument cluster to replace the bulb, assuming that is the problem.

Caravan won't start after shifter cable replaced


Make sure the transmission range selector switch is adjusted correctly it is the switch just below the shift cable post. Also try to start it in Neutral rather than park position.

1997 gmc 1500 went to start and tach and speed odometer not working and transmission shifts in hard and wont shift down stays in like high gear


Check transmission fuse its the one labeled PRNDL or similar.Use a test light when you check it by the way.If the fuse is good then its probaly your ignition switch failed.If that fuse is bad or the ignition switch is not suppling power to that fuse your tack,speedo,and gear indicator wont work, and your transmission will go into a safe mode.Safe mode is just the transmission staying in 3rd gear all the time until you fix this.

Plymouth grand voyager 1999 is not showing the readings on my dash for the fuel, speedometer, and has not passed emissions. What could be the problem?


Here is the procedure to check the gage connector on the back of the instrument cluster. The procedure is a lot longer if you have a mechanical PRNDL indicator in the cluster. I'm thinking you don't. You don't need to remove the cluster as the procedure says, because you're just going to check the connectors on the back. You just need to take the screws out and tilt it forward far enough to reach in and push the connectors in.

Dash indicates transmission is always in Drive. Transmission shifts through all gears but indicator does not change. Vehicle will not start.


You have a electronic Shift indicator switch on your transmission this is also called th NSBU switch. This is what tells your instrument cluster what gear you have selected. This may be your problem. or you may have a loose or bad connection. NSBU stands for neutral safety Back up switch.

97 Chevy truck cluster and transmission


I would say its your Ignition switch or the fuse for tranny is blown or the tranny is unplugged.My truck had a problem where it was stuck in third gear, the tach never moved,the gear indicator light went out.I left it at the tranny shop all day and nobody could find the problem.All you need to do is check your fuses with a test light.I looked at all my fuses and they were all good but when I used a test I found that some fuses didnt have power supplied to them from the ignition switch.Your fuses need power on both sides to complete that circiut.So I would say go get a test light because they are cheap and check your fuses before you go right back to the parts store for that ignition switch.Good Luck
