Transmission wont engage I have had no recent problems

Truck listed above 1500 was submerged in water. Changed filter and canister filter, new fluid and a bottle of sea foam transmission conditioner. Cleaned all the plugs and dried them. Reset the TCM, but the truck will not go into any gear.

Shift lever seems to go into Park position, but idiot light on dashboard shows Reverse, and engine will shut off and act as if it is in park. But the truck will not start unless placed into neutral. Transmission does not actually shift into any gear at all. Seems to be stuck in Neutral. Even though shift lever on column goes to the park position the Park light never comes on just Reverse and truck will only start in Neutral, it does stop in the R with the column shift vlever in the appearant park position. There were No warning signs at all that I noticed. I just pulled into my drive way to park after driving home from work and driving around town running errands Yesterday. The truck drove fine all day it has been rnning rough in idle and at slow speeds, like it is due for a tune up which is past due really. (The dealer want's $600.00 for a Dealer so called "Full Service Tune-up" on this thing) but no obvious warning signs that I noticed until this problem happenned. I did try to shift it into and out of 4X4 and it does seem to shift into and out of 4X4 but with a lot of hard clunking of the drive train or axle and efforft to get it to go into and out of 4X4, still does not move in any drive position selected.

Had sort of same problem drove home put it in park went to put it in reverse nothing turned out the snap ring broke and took out my reverse no warning signs at all. Drop your tranny pan and see if you have anything siitting in it that should not be there

Well I was on the highway coming home and started going up a hill and when my truck down shifted it made a loud noise and then there was nothing couldn't go forward or backwards I put it in drive it starts rolling backwards put it in revers nothing the only gear that works is park other then that there is nothing fluid is good I don't have a clue on what could be wrong can u help me? Please

Truck has had a problem sometimes starting in drive for a while now not a big deal just start it in neutral! Well now I went to start my truck had no problem, pulled it out of the garage put it into park, let it run for like 5 minutes get back in it and Now it won't engage into any gear, tried to put it back into park while running and it grinds/clicks put it into park with it off and it still will roll I have the tranny pan off and the linkage looks fine and everything moves as it should! Why won't my transmission engage? No codes either! Btw trans fluid was perfect and absolutely no metal shavings on the magnet in the tranny pan! Solenoid? If so which one? Please help! Thankyou, Luke.

Alright this is the farthest ive gotten! 4x4 is in nutral however when this all happend I put it in 4x4 to see what would happen while running and it didnt chatter as I put it in park however it didnt engage either?Its just so confusing this all happend two days go. Just a little bit ago I went out there tranny pan still off I turned the key shifted it and it engaged into park.(Wont roll as it did) so im assuming its gonna work now? But there was or still is something wrong would the transfercase need to be replaced? Also the problem starting in park sometimes but never a problem starting in nutral. Is this gonna be the nutral saftey switch? I appreciate all ur help and also if you keep helping me I dont have any problem donating more money>. Thanks, luke

Alright thanks again for ur help! Back to my engaging problem though? U had metioned the transfer case? I'm gonna put it back together tomorrow and if it does work, great but who's to say it's not gonna happen again? So what would need to be done? And thanks again for helping me, when I make well a (tip) is it gonna get to u again?

Please help! I am having the same problem, but have tried all of the above. Also, it starts in ANY gear and still rolls even in park! Linkage adjustment was done and then still starts with both connections to trans unplugged? Wow confused.

Transmission will not engage in drive but will in reverse, second and first. Made sure transfer case is in two wheel drive.

My truck was driving just fine and suddenly it just stopped going. It won't go into any gear at all. It feels like it shifts I to gear but does not go at all.

In line at drive thru, put in park, then moved on in drive, put pack in park, tried to move into drive, nothing, except car now goes backwards, tried to put it in any other gear, no luck, still going backwards. After a while of flipping thru gears and nothing except backwards going, I turned the engine off and two guys helped push car out of drive thru. Now, since truck is in reverse stuck, it won't start because it's not in park or neutral. I didn't have nay problems before with the tranny shifting not smoothly. Could it be the gear shifter in the steering wheel or tranny? Any other ideas? What am I looking at spending approximately?
