Anyone have any idea?

If you feel the truck lurch forward in drive and backwards in reverse, I would suspect stuck brakes or the parking brake is stuck on due to a bad cable or something. If it doesn't lurch, try giving it some gas and see if it feels like it wants to go back or forward. If no movement at all, i would check the transmission fluid (Remember that you check this while the engine is idling). If the fluid level is in the cold range, i would suspect a failed transmission pump or a failed torque converter. If this is 4x4- check to make sure that the transfer case is in 2hi and not in neutral.

Sounds like your transfer case in neutral. You have to engage the transfer case back into gear then shift selector to drive or reverse. When your transfer is in neutral the transmission will not operate. Good luck.

If it is a four wheel drive check your tail shaft or drive line by securing the vehicles front wheels jack up the rear tires and in park try to rotate the drive line if you can hear the transmission sound like it is going into gear the transfer case could be damaged! If not a four wheel drive pull the transmission dipstick and look to see if the fluid is dark red or metallic grayish color if so then you're clutch disks inside the tyranny have been worn out and it needs to be rebuilt!

it sounds like the transfer case is in neutral good test start truck place trans in reverse slowly try to place back in park if it makes any noise then the output shaft of transmission is turning then problem is in transfer case move that lever back & forth several times this might get it working again

run fault codes and look for faulty TCM and reverse servo .

It sounds like you may have a brake caliper sticking (if the issue is really coming from the front). Does it pull in one direction? One way to check is to jack the front end up and try to spin each tire by hand. They should turn relatively freely. Another possibility, and more likely from your description, is that the rear emergency / parking brake may be frozen. Drum brakes, by nature, do a better job of holding the vehicle from rolling forward. If your emergency / parking brake is engaged, either frozen or inadvertently left on, I would expect the symptoms you describe- moving in reverse, but not forward. You can check this the same way- jack up the rear end of the vehicle, put it in neutral, and try spinning the rear tires by hand.

Assuming your vehicle is a 4x4, a less likely scenario is that something's gone awry in the transfer case, front differential, axles, hubs.

Good luck.

4l60e or 4l80e transmission?

i would say the fine grinding was when you put it in park the output shaft was turning and the parking paw was trying to engage into park then the paw engaged into park but you say it rolled i am thinking that your problem is in the transfercase

As far as I know the procedure should go something like this...

Stop the vehicle, engage the parking brake and if applicable, get out and turn the hubs on the front wheels from Free, to Lock.(You may not have these on a Suzuki, they may be auto-lockers)

Get back in the vehicle and put the transmission shift selector into Neutral.

If you have a manual transfer case, move the selector-shaft to 4x4-High, or 4x4-Low -- whichever is desired. Now, putting the vehicle in gear with the transfer case is sometimes somewhat difficult. As long as the vehicle's transmission is in neutral, don't worry, the gears inside the transfer case are big and beefy -- Don't be afraid to be rough -- Again as long as the transmission is in neutral. You may also have to disengage the parking brake and slightly let the vehicle roll forward or back with your foot-brake to get the Transfer case to lock into place.

Once 4x4 of the selected High, Or Low range is selected, usually indicated by the vehicle jerking slightly with a slightly loud clank/thud. Move the Transmission selector out of neutral into your desired gear (Drive if Automatic, if Manual, whichever gear you pull out from). and voila! You should now be in 4-Wheel-Drive.

To disengage 4-Wheel-Drive. Just reverse the steps.
