I have a 2003 chevy S-10 4x4 crew cab we are wanting to tow behind a motor home. I was wondering how you can put the transfer case into neutral, so we dont have to car dolly it everywhere?


Some customers may want to tow their vehicle behind another vehicle with all FOUR tires on the ground. This is referred to as "dinghy" towing.
Towing in this manner is acceptable only on the certain vehicles. The vehicle should be properly equipped and prepared as described below.
The passenger cars listed above are the vehicles that CAN be dinghy towed. Passenger cars not listed above are vehicles where dinghy towing is not permitted or recommended.
Certain 4WD trucks can be dinghy towed depending on the transfer case option. Rear wheel drive and AWD trucks should NOT be dinghy towed. Refer to the truck models and transfer case options below.
Please refer to the applicable vehicle Owner's Manual before towing.
Passenger Cars Notice: These vehicles must not be towed backwards or transmission damage may occur.

Important: The towing speed as stated in the Owner's Manual should not exceed 104 km/h (65 mph) for 1995-2005 vehicles.
In order to properly dinghy tow the vehicle, follow these steps:
  1. Firmly set the parking brake.
  2. Open the fuse panel and pull the fuse(s) indicated in the Owner's Manual section detailing towing your vehicle. This prevents the instrument panel (IP) and/or electronic PRNDL indicator from draining the battery.
  3. Securely attach the vehicle to the tow vehicle.
  4. Turn the ignition key to the OFF position, which is one position forward of LOCK. Unlocking the steering column allows for proper movement of the front wheels and tires during towing.
  5. For 1997-1999 Cutlass, 1997-2003 Malibu, 2004-2006 Chevrolet Classic and 1999-2004 Alero/Grand Am models, turn the ignition switch to the accessory (ACC) position, which is one position forward of OFF. This position unlocks the transaxle.
  6. Shift the transmission to Neutral (N).
  7. Notice: Use extra care whenever towing another vehicle. Do not exceed the towing vehicle's gross combination weight (GCW) by adding the weight of the dinghy towed vehicle or vehicle damage may result.
  8. When the vehicle being towed is firmly attached to the tow vehicle, release the parking brake.
  9. Replace the fuse(s) in the fuse panel when finished towing.

Turbo 400 transmision only goes in gear for i second then pops out


First thing to do is check your fluid level, which must be done with the engine running. If the level is low, fill to correct level and try again. If fluid level is ok, I suggest changing the trans filter. If that doesn't help, I suggest changing the transmission, or getting it rebuilt.

Some owners of the above models equipped with a Hydra-Matic 4T65-E transaxle with a Julian Date prior to 0045 may comment on a whine noise in PARK and/or NEUTRAL or a Service Engine Soon or Service Vehicle Soon lamp that is illuminated. Upon investigation, a DTC P0741 or P0742 may be found.

Cause:
The above condition may be due to drive sprocket support bearing fluting and/or bearing failure.

Correction:
Replace the drive sprocket support bearing. Inspect the channel plate and drive sprocket for any abnormal wear, Turbine shaft for cut seals and/or nicks, and chain for excessive play due to failed bearings.

Important:
When installing the new bearing, the part number MUST be visible (facing upward). Before installing the drive sprocket, lubricate the bearing assembly with J 36850 assembly lubricant.

Refer to the 4T65-E Unit Repair Section for the installation procedure.

Service Part Information:
Part Number: 24214158
Description: Drive Sprocket Support Bearing


Parts are currently available from GMSPO.


Its possible that you can use a voltmeter to test for power and ground at the TCC solenoid connector and also resistance across the solenoid. The scan tool is helpful in pulling the codes, commanding the TCC on and off and monitoring the state of command while driving.

Hope help with this (remem,ber comment and rated this).
