Where is the neutral safety switch on a2004 chevy Malibu, 3.5 L engine


The transmission range (TR) switch is part of the park/neutral position (PNP) and back-up lamp switch assembly (1), 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. By grounding one or more of the switch circuits, the PCM detects the selected gear range by the state change of the switch input. Refer to Transmission Range Switch Logic . Switch input to the PCM is represented on the scan tool as HI and LOW. HI indicates an ignition voltage signal. LOW indicates a zero voltage signal. The four parameters represent transmission range switch signal A,B,C and Parity.

Look on transmission where the shifter cable hooks up !

How do I fix the transmission problem? The car is moving forward at neutral, drive and low gear, and switching to parking mode at reverse and parking. The car is not backing up at all.


Transmission may now be toast since you continued to drive it when maybe low on fluid or torque converter had failed. How long since last fluid and filter change? Ever?

Will the neutral safety switch keep it from shifting out of low gear?


The neutral safety switch should not affect the shifting of the transmission. The neutral safety switch is there just to make sure that you have the transmission in park or neutral when cranking the engine. It is just a safety mechanism to prevent cranking while in forward or reverse and having the car lurch forward or backward.

Precor error codes 53


Precor Error 53, Can't Read Target, Can't Find Home Switch Probable Cause 1. Blown F2 fuse.
2. Home switch wiring is damaged or has intermittent connection.
3. Gear (elevation/incline) motor wiring is damaged or has intermittent connection.
4. Home switch is bad.
5. Gear (elevation/incline) motor is bad.
6. Gear (elevation/incline) motor target is damaged.
7. Lower PCA is bad.
Corrective Action
  1. Disconnect power from the unit. Remove the F2 fuse from the lower PCA. Using an ohm meter, measure the fuse for 1 ohm or less. If the reading is considerably high, replace the fuse. If the fuse is blown, inspect further for the cause to avoid the fuse blowing again. Inspect for damaged gear motor wiring or a bad gear (elevation/incline) motor. Replace if necessary.
  2. Thoroughly inspect the home switch wiring for damage or intermittent connections. Repair or replace damaged wiring or poor connections as necessary.
  3. Thoroughly inspect the gear (elevation/incline) motor wiring for damage or intermittent connections. Repair or replace damaged wiring or poor connections as necessary.
  4. Ensure the moving arm is away from the home switch and disconnect power from the unit. Disconnect both wires from the home switch. Using an ohm meter, check for approximately 0 ohms. Continue to monitor the home switch resistance and activate the home switch by hand. The reading should change from approximately 0 ohms to open (infinite). If either reading is considerably incorrect, replace the home switch.
  5. With unit disconnected from power, disconnect both wires from the gear (elevation/incline) motor. Using an ohm meter, check for approximately 9 ohms through the gear (elevation/incline) motor wiring. If the reading is considerably high or low, replace the gear motor.
  6. Inspect the gear (elevation/incline) motor target for rips, tears, or bad scratches. If any of these are found, replace the target.
  7. During the start up sequence, check the voltage at the gear (elevation/incline) motor. Voltage should be approximately 12VDC. The voltage should only be present between the time the sequence was started and the error 53 occurred. If the voltage is considerably low or absent and the F2 fuse proved good, replace the lower PCA.

2001 Dodge Ram 1500 3.9 V6 Seems not to go into low gear anymore - also, won't kick down into low even at low rpm. Anyone got a fix?


You may have a leak in the vacuum line which tells the tranny to switch gears, or it may have an electrical sensor instead of a vacuum line, Most new trannys are controled by electrical signals from sensors

Stuck in low gear won't go in to hi gear


Just a suggestion...if you are talking about the two speed transfer case, the vehicle must be running and in neutral to switch between gear ranges. Neutral, running, foot on braks and then try switching gear ranges, Hope this is the answer you are looking for. If not, explain more what you are seeking.

1955 Ford Crwn Vic neutral switch will permit start in any gear not just neut or park. Is this a 2 or 3 speed auto transmission? will start in drive selection and only shift once witn no kickdown gear at...


A 1955 Ford would have a Ford-o-matic transmission which has three speeds forward. The transmission starts out in second gear unless you shift into low.
I am not aware of these transmissions having a neutral safety switch.
The 3 speed automatic transmissions that started in low and had a downshift to second under load were first used in the mid 1960s.

winter mode engages take of in 3rd gear. sounds like you have got a serious trans problem, mainly with lower gears. Can you manually select low or 1st gear and get it?
if you can then range selector switch could be faulty(neutral saftey switch) is the P,R,N,D,2,L lighting up in instrument cluster to display what gear your in? if its not working properly then range selection switch is faulty
