Can i remove my transfer case on my 2006 Outlander 2.4 gls auto and drive without it, if so what mods are needed.

Question edited for clarity.
Question moved to model category.

Unfortunately there is no way to do that. The security system and engine immobilizer is there to stop exactly what you are trying to do, drive the car without the correct credentials. All this is controlled by two computers, a module and various sensors.

The trick is to get a new key when you lost key number 2 and was left with only one key left.

Now you need the dealership or an auto-locksmith. And by the sounds of it, a friend or a taxi. Good luck with your daughter.

This vehicle had option of three different transfer case ! Which one of these is the one in your vehicle ?
Transfer Case - NVG 120-NR9 Transfer Case - NVG 126-NP4 Transfer Case - NVG 226-NP8
The New Venture Gear model NVG 226 RPO NP8 transfer case is a two speed automatic, active, transfer case. The NVG 226 provides five modes, Auto 4WD, 4 HI, 4 LO, 2 HI and Neutral. The Auto 4WD position allows the capability of an active transfer case, which provides the benefits of on-demand torque biasing wet clutch and easy vehicle tuning through software calibrations. The software calibrations allow more features such as flexible adapt ready position and clutch preload torque levels. The technology allows for vehicle speed dependent clutch torque levels to enhance the performance of the system. For example, the system is calibrated to provide 0-5 lb ft of clutch torque during low speed, low engine torque operation, and predetermined higher torque for 32 km/h (20 mph) and greater. This prevents crow-hop and binding at low speeds and provides higher torque biases at higher vehicle speeds, to enhance stability.
The New Venture Gear model NVG 126 RPO NP4 transfer case is a one speed automatic, active, transfer case. The NVG 126 provides only one mode, Auto 4WD, and is transparent to the operator. The active transfer case provides the benefits of on-demand torque biasing, wet clutch and easy vehicle tuning through software calibrations. The software calibrations allow more features, such as flexible adapt ready position and clutch pre-load torque levels. The technology allows for vehicle speed dependent clutch torque levels to enhance the performance of the system. For example, the system is calibrated to provide 0-7 N?·m (0-62 lb in) of clutch torque during low speed, low engine torque operation, and predetermined higher torque for 32 km/h (20 mph) and greater. This prevents crow-hop and binding at low speeds, and provides higher torque biases at higher vehicle speeds, to enhance stability
The New Venture Gear (NVG) model NV120, RPO NR9 transfer case is a single speed, full-time, all wheel drive (AWD), transfer case that incorporates a front/rear drive differential carrier assembly.

this question sure depends on make and model car , rear drive cars can usually be done without removing the engine from car in less than a day , but most front wheel drive cars no way you can access it while engine is in car this makes it a two day event , I do question ? why you think you need a new oil pump ,U know if engine ran more than a few minutes without proper oil pressure , its sure to be well worn out internally , id sure be looking real carefull for metal bits in oil that's drained from car , coffee filters are perfect for this task , most times this requires a engine swap !!

check for worn loose "u" joints . check for loose drive shaft pinion. Check for worn suspension rubbers on rear end allowing the arms to move up and down

First of all, the noise is not coming from the rear. The noise is only happening in 4WD mode, that involves the transfer case and front differential.
When was the last time the transfer case fluid change, it is recommended that it be changed every 50K miles. It is possible that you have transfer case issues. It is not recommended to operate the drive system in Auto mode constantly, this will wear out the internal clutches.
If the road surface does not warrant 4 wheel drive, keep the selector in 2WD.

Vehicles: 2002 Chevrolet Trailblazer 4WD 4.2L SFI DOHC 6-cylinder

Your front 4WD Transfer case is low on Gear Oil.
On warm days, the Gear Oil expands slightly, and is less viscous, so the "Service 4WD" light stays off. On colder days/mornings the story changes.

The following paragraph has info applying to the manual differential only:
The 2002 Trailblazer (the first year Chevy made the Trailblazer) has a Front Differential using 1.11 (that's 1 and 1/9th) Quarts Gear Oil, and a Rear Differential with a capacity of 2.29 (thats 2 and 2/7ths) Quarts Gear Oil.
The Gear Oil needed is GM Part No.12345349 or GM Part No.1052931 (they're identical), also known as "GM Synchromesh"(R), which is a type of GLS (Gear Lubricant, Special), also known as "Manual Synchromesh Transmission Fluid 5W30". A synthetic version of which sells for $12.70/qt (USD) at
http://www.amsoil.com/storefront/mtf.aspx

This is not to be confused with 5W30 motor oil (which can be had for $3.00/qt (USD)).

The 2002 Trailblazer 4WD Transfer Case (NV126 Transfer Case) capacity is 0.8 Liters of GM Part No.12378508 (US), also known as "GM Auto Trak II"(R).
Note that one Quart (US) = 0.946 Liter, so 0.8 Liter = 27.06 ounces.

Red Line sells something that they say replaces both GM Synchromesh and GM Auto-Trak II for $12.14/Qt and $44.55/Gal (US) at

13 Manufacturer Recalls apply to the 2002 Chevrolet Trailblazer (model year 2002 was the first year Chevy offered the Trailblazer), and two recalls pertain to the 4WD Transfer Case. Note that one of the recalls applies to only 895 units, so your vehicle is unlikely to be affected by this Transfer Case recall.

It depends on what transfer case you have in your vehicle.There are 4 different types.The best way to tell is go into the glove box and on the bottom there is a small decal sticker about the size of a credit card it will have the info you need.Look for the NP codes i.e.NP8.NP1,NP2,NP3or NP8.I`ll give you the G.M.part numbers.NP1,NP2,and NP3, are the same 88861800.NP8 takes Auto-Trak 2 12378508.They take 2 quarts.Hope this helps.Good luck.

remove drive shafts remove cross member, and transfer case mount remove transfer case then remove tranny there are 6 bell housing bolts that hold tranny in 15 mm i think and 2 trany lines if its auto

possibles--chech and test 4wd / transfer case module --faulty switch --- transfer case failing

Oh lord, are you in for some work. First of all you will need a transmission jack, a must and a couple of strong guys if you don't have a lift. First things first. Disconnect neg. bat. cable. Raise up on jack stands. Disconnect drive shafts and tape bearings caps on drive shafts. Remove Starter. Disconnect wiring harness plugs from transmission and transfer case. The wiring harness connection on the shift linkage does not remove. There are 2 connectors and are glued at factory. Remove whole shift linkage unit from side of trans. Remove exhaust. Remove dust cover. Mark spot on flywheel and tourque converter, then remove bolts from flywheel. Support trans. with jack. Remove transfer case bolts from trans. Remove mount nuts from transfer case bolts. Remove bell housing bolts from motor to trans. Remove bolts from crossover support for transfer case mount from the main frame. Raise up transmission and remove crossover support. One guy now supports transfer case and other works transfer case loose. The transfer has to be jockeyed around until it drops out. It will not come straight out or down because of the tor. bar support frame. It has to be wiggled out and down. Guy supporting transfer case gets trans fluid bath and this is all muscle work. With transfer case out, put another jack under motor for support or risk breaking motor mounts and other things. Slide transmission back and lower down and its free, It is a very dirty, oily, nasty hard job. I just went through it. I wouldn't do it again. If you can afford it, take it to a pro. Well worth it. Remember once started, your pretty much commited. Reverse the whole thing to install. Good Luck
