2001 Impala doesn't go into park, when I put it into park it registers as reverse & have to put gearshift in neutral position to start it with turning the key to the ACC setting . Tranny has already been rebuilt less than 2 years ago, I don't shift the car while it's still moving so I'm not sure why this has happened again. Is there a simple fix for this?

Re: Impala doesn't go into park
I suspect that there is a simple fix.
Under the car.... at the point where the shift lever rod connects to the transmission shift lever(s)...... loosen the nut on the Park transmission shift lever... and place the lever all the way into the park position.... You can confirm by attempting to start the car....
Once you are sure that it is in "Park", you can tighten the shift lever nut....
a 6ya expert can help you resolve that issue over the phone in a minute or two.

P=park gear position (no gear selected)
R=reverse gear position
N=neutral gear position (no gear selected)
2=fixed highest gear (used for speed when climbing an average incline and to control speed on decent)
1=fixed lowest gear (used for climbing steep incline or descending slowly)
Note-: Never engage Reverse gear when traveling forwards and never put into Park when moving forward or backwards, also towing most autos should be done no more than 10mph, fast towing can damage the gearbox, also make sure gear is in Neutral when towing.
The circuit on newer cars with automatic transmissions has a neutral safety, or neutral start switch installed between the ignition switch and the starter. The ignition switch cannot operate the starter motor unless the transmission is in park or neutral.
Late model vehicles with manual transmissions have a starter/clutch interlock switch that requires the clutch to be depressed to the floor. Neutral Safety Switch
Normal operations of a neutral safety switch provides a quick check for the adjustment of the gear selector linkage.
To do this, move the selector slowly until it clicks into the PARK position.
Turn the ignition key to the START position.
If the starter operates, the PARK position is correct.
After checking the PARK position, move the lever slowly toward the NEUTRAL position until the lever drops at the end of the NEUTRAL stop in the selector gate.
If the starter also operates at this point, the gearshift linkage is properly adjusted.
This quick test also tests the adjustment of the neutral safety switch.
If the engine does not start in either or both of these positions, the neutral safety switch or the gear selector linkage needs adjustment or repair.
CAUTION Since you must work under the vehicle to adjust most shift linkages make sure you properly raise and support the vehicle before working under it. Also, wear safety glasses or goggles while working under the vehicle.
A voltmeter can be used to check the switch for voltage when the ignition key is turned to the START position with the shift lever in PARK or NEUTRAL. If there is no voltage, the switch should be adjusted or replaced.
I went to get in my car tonight to leave and my console gear shift would not shift out of park. The gear shift button will not press in. Absolutely nothing! I have a 2007 Chevrolet Impala. Anyone know of this problem and what is the solution?
Check 1 The Park/Neutral/Back-up light switch has a black colored insulator and is located at the lower left hand side of the transaxle near the oil pan. The switch inhibits starter motor engagement unless the gearshift lever is in the PARK or NEUTRAL position and completes the back-up light circuit when the gearshift lever is placed in REVERSE. 2 Prior to checking the switch, first make sure the shift cable is adjusted properly (see Section 4). 3 Raise the vehicle and support it securely on jackstands. Extract the 2 push-in fasteners and remove the transaxle splash shield. 4 Disconnect the electrical connector from the Park/Neutral/Back-up light switch. 5 Using an ohmmeter, check for continuity between the center terminal of the switch and the switch body. Continuity should only be present with the gearshift lever in PARK and NEUTRAL. If continuity is detected with the gearshift lever in any other position, replace the switch. 6 Next, check for continuity between the t wo outer terminals. Continuity should only exist with the gearshift lever in the Reverse position. Check the for continuity between each of the outer terminals and the switch body. No continuity should be present. Replace the switch if it fails any of these checks. 7 Install the transaxle splash shield and secure it with the 2 push-in fasteners. Lower the vehicle. Replacement Refer to illustration 6.10 8 Raise the vehicle and support it securely on jackstands. Extract the 2 push-in fasteners and remove the transaxle splash shield. 9 Working under the vehicle, disconnect the electrical connector from the switch. Place a drain container under the transaxle as some fluid loss will occur. 10 Unscrew the switch from the transaxle using a box-end wrench (see illustration). Discard the switch seal. 11 Look into the switch opening in the transaxle. Have an assistant shift the transaxle from PARK to NEUTRAL. Check that the internal operating fingers are centered in the switch opening. 12 Install the new switch and seal into the transaxle and tighten the switch to the torque li sted in this Chapter's Specification Section. 13 Recheck the switch operation (see Steps 1 through 6). 14 Attach the switch electrical connector, install the transaxle splash shield and lower the vehicle. 15 Check the transaxle fluid level and add more, if necessary (see Chapter 1).
it sounds like your gearshift cable is broken..if you can jack up vehicle and support it safely,get someone to move shifter and look on driver's side of transmission and see if linkage is moving on trans..linkage is up near top of trans..i have seen this problem before
The gear range switch on the back of the transmission is either bad or out of adjustment. To adjust, try removing the switch and put it in the neutral position (it should click into this spot). Then put the transmission in neutral and reinstall the switch being careful not to let the switch turn at all during re-install. There is a few degrees of adjustment available by turning the switch in either direction as well if it is still off. The car should only start in park or neutral and the reverse lights should only come on when in reverse.
Digital Transmission Range Sensor
The digital transmission range (TR) sensor is located on the outside of the transmission at the manual lever. The digital TR sensor completes the start circuit in Park and Neutral, the back-up lamp circuit in Reverse and the neutral sense circuit (4x4 only) in Neutral. The digital TR sensor also opens and closes a set of four switches that are monitored by the PCM to determine the position of the manual lever (P, R, N, D, 2, 1).
I'm not sure what you mean by "neutral safety switch". I have the shop manual for this car (I also have a 2001) and there is nothing listed under "neutral" or "safety" or "switch" in the index that looks like it.
