Nedd help no drive or reverse

I have just brought a run down 01 Quad cab v6 auto TRD. 6" lift with 35 boggers. The rearend was cracked. So I fixed that and replaced it with a stock one . I gave it a power wash under the hood and chassis. Then I decided to chance it and drive about 30 mins away to pick up my kids. Driving there was no problems drove fine but on the way back I let go of the gas a little and went to reapply and all I got was the rpm going up but wasn't going anywhere . So I put it in n and back to d and nothing then I tried reverse and nothing then I tried to put it in park and it was grinding .so I then put it in neutral and put it in 4h and then in d and it went then I tried to put it back in regular drive and a no go so I then put it back in 4h and drove it the rest of the way home. When I reach home I tried playing around with it but no luck.. Yes the at light does come on. I have searched and found something about transfer case mispositing....but nothing specific .....need the help badly any info is appreciated..

Thanks

 

x2 or transfer case if the front wheels work

 

Did it shift through the gears in 4H? or was it stuck in a single gear?
or did you have to manually shift the gears in 4H?

Sounds like something is wrong with your transfer case.

If it drove in 4H..then the transmission obviously works.

 

It shifted perfectly fine in 4h without any problems it also goes into park without only problems...but in regular it will grind when I put it in park

 

did you pressure wash the engine? cause i had a buddy who did that and it totally messed it up

 

probably...he isn't exactly the brightest person ever

 

That is definitely a t case issue IMO.
Cheaper then a transmission.

 

Yeah I pressured was the engine bay but just skimmed the engine but mostly did around it...do I need to reposition the t case or replace it
