Gaurav Posted May 23, 2020 Report Share Posted May 23, 2020 Transfer case shifting from LO to HI without stopping happened today and transfer case got stuck in neutral. Here are the steps needed to bring back Hi/Lo selector back in its place. Mitsubishi issued the TSB back in 2001 for the same. MITSUBISHI MOTORS TECHNICAL INFORMATION TECHNICAL SERVICE BULLETIN SUBJECT: No: TSB-01 -23-002 TRANSFER LEVER STUCK IN 4H DATE: February 2001 On 4-wheel-drive models, shifting from 4L to 4H should only be done with the vehicle stopped and the transmission in Neutral. If the driver forces the transfer lever from 4L to 4H while the vehicle is moving, the lever may become stuck in 4H. If the transfer lever goes from the H-L shift fork to the 2-4WD shift fork while the vehicle is moving, the clutch sleeve is forced to return to the low speed gear when it hits the chamfer of the input gear. As a result, the lever is in 4H, but the gear is engaged in 4L. This bulletin describes how to adjust the transfer shift forks to eliminate this condition. AFFECTED VEHICLES 1997-2001 Montero Sport models equipped with 4-wheel-drive FILE UNDER: Group 23 Automatic Transmission in the Dealer Service Information Binder (2239) This bulletin supercedes TSB- 00-23-004, issued May, 2000, to correct affected vehicles, shift lever bolt identification, and shift fork positioning Corrections are indicated by ‘b." BOOT TRANSFER LEVER TRANSFER SHIFT LEVER TRANSFER LEVER BRACKET TSB-01 -23-002 PROCEDURE Remove the transfer lever shift knob. Remove the center console. Remove the transfer lever bracket (6 bolts). Lift the boot up and remove the shill lever (4 bolts). Disconnect the vent line from the shift boot. Check the location of the H-L shift fork. If it is not in the H position, use a brass punch to push the shift fork toward the front of the vehicle. Check the location of the 2-4WD shift fork. If it is not in 2WD, use a brass punch to push the shift fork toward the front of the vehicle. If necessary, adjust the return spring so it can be set with the 2-4WD shift fork. IMPORTANT: Do not place the return spring in the gap between the H-L shift fork and the 2-4WD shift fork. Remove the old sealant adhesive from the transfer lever and housing contact surfaces. Apply Mitsubishi Silicone Gasket Sealant TSB1 215 (p/n A99OZC1 X02) or equivalent to the transfer lever and housing contact surfaces. Place the end of the transfer lever in the 2-4WD shift fork and reinstall the lever into the housing. Set the return spring. Confirm that the transfer lever can be moved smoothly. Tighten the bolts securing the lever to 15-22 Nm (11-16 ft/lbs). Reinstall the transfer lever boot bracket. Reinstall the center console. Reinstall the transfer lever shift knob. Advise the owner of proper transfer lever operation: Shift from 4L to 4H only with the vehicle stopped and the transmission in Neutral.

Barry Posted May 24, 2020 Report Share Posted May 24, 2020 @Gaurav didn’t this happen to you before also? I remember reading an article about a plastic bush that fails on the linkage that causes this. 2 Link to comment Share on other sites More sharing options...

I remember reading an article about a plastic bush that fails on the linkage that causes this. Yes it did, and it wasn't a plastic bush, it was a metal nut fallen into the gear oil. Luckily nothing happen. Yesterday it happened again and transfer case went to neutral, as I pulled from LO to Hi without looking down as I was under the impression that I'm in HI and wanted to shift to 2WD from 4WD, without stopping (which is normal). I hope Mitsubishi sorted this in newer Pajero by installing some fail safe mechanism to prevent driver making such horrible mistakes. 8 hours ago, Frederic said: Fantastic write-up and very helpful in case it ever happens to me 😅 Never ever switch to Hi - Lo or vice versa without stopping. 2WD - 4WD and even 4HLC you can do without stopping, with just drive gear in neutral. 2 Let's root for each other & watch each other grow.

Shiju Manuel Posted May 24, 2020 Report Share Posted May 24, 2020 very informative, once i do this mistake in one of the drive, i shifted the gear from 4H to 4LLc with out changing the gear to neutral and the gear did not engage 4LLc in dash board i could see the light was just blinking. some time what i did is while the car is moving i shifted to neutral and change the gear 2WD to 4WD and 4HLC. I don't know is it any harmful to the gear box. Mine is 2015 model Pajero. 2 Link to comment Share on other sites More sharing options...

That means Mitsubishi have done some fail safe in new Pajero's. Please dont do that gain. Always stop before you shift from LO-HI and vice versa, also make sure you are in Neutral gear and not in D or Parking. 2 Let's root for each other & watch each other grow.

The difference between a mechanical 4x4 shifting (Gen 2) vs the electronic 4x4 shifting (Gen 3) onwards. The computers don't allow it to engage unless you have to come to a complete halt and are in Neutral. In my XJ which is also a mechanical shift, the 4x4 doesn't allow under normal pressure to go-to 4Lo when the car is in motion or in gear. I think overall it would be a good or safe practice to always shift the 4x4 transfer case while it's stationary, even if it's from 2wd to 4wd 3 2 Link to comment Share on other sites More sharing options...

Has happened to me on my manual Land Cruiser on the washboard gatch tracks of Hatta. The gear was left in 3rd and the lever totally free. Had to drive all the way from Hatta to Ghusais in 3rd. Luckily here also it just fell to the bottom and did not grind in any of the gears. Had to fish it out with a long magnet. 3 Link to comment Share on other sites More sharing options...
