I have a 2001 Chevy 2500 HD With the duramax diesel and allison tranny. I am having issues with the truck shifting into 4x4. I pulled the actuator motor off the side of the transfer case and tested it. It turns just fine. I jacked the passenger side front tire off the ground and tried engaging the transfercase manually the tire wouldn't lock. I drained all the fluid from the transfer case and found no metal flakes. I am at a loss and debating on whether to pull the transfer case. Any Ideas

SOURCE: My 2002 2500HD 4x4 front axle not engaging

Try jacking up one side of the front and putting it on a jackstand. Then turn key on(but dont start it) and put it in 4hi. Try to spin the tire in the air. The drive shaft should not turn nor the wheel. If the wheel does then maybe the acuator is not moving in the axle. It worked when you pulled it out but it might be hanging up on something in the axle.

Will a transmission from 2003 duramax fit in a 2004 duramax?


They will deefinitely providing the 2 are the same model. In 2004 the Allison tranny was available in a 5 or a 6 speed. Before 2004 only the 5 speed was used. If one is changed for the other there will be shifting issues and codes set in both the ECM (engine control computer) and TCM (transmission control computer). Make sure you are putting in a 5 speed Allison tranny.

I own a 2006 Duramax Diesel 2500, with Allison Transmission and would like to know if I can tow this truck behind a Motorhome? Is there anything special I need to do?


Sounds like you should tow the motorhome with the 2500!!

seriously though, if it's a 4X4 make sure the front axle is not engaged, otherwise just make sure tranny is in neutral

just to be safe, check OM or nearest Allison warranty shop for advice

I'd be more worried about the motorhome drivetrain pulling that beast.....

4X4 inop on 2003 GMC Sierra 2500HD


I have found that when you are going to engauge 4x4 high, it is best to only be going about 3 miles an hour. Not faster, not stopped. It likes some movement to help it mesh. I've had perfect shifts since I started this. Hope it helps. Wade.
