So i had a little mishap a week ago and long story short my truck was submerged and now the transmission/clutch isn't working properly. I stupidly pressed the clutch while it was under water so that may be a problem. When i release the clutch in neutral everything is fine, but when i release it in any gear it just grinds and will catch every now and then and actually move forward some. Any help would be appreciated before is start tearing into it.

 

I would start by draining the fluid your trans is not water tight and you most likely have some in there. Water does not lubricate gears well lol.

 

Clutch hydraulics is a sealed system, so whether you pushed the clutch in or not wouldn't matter.

Because there is no "grinding" with clutch out in Neutral, the clutch is not your issue.
The clutch disengages the flywheel from the transmission's input shaft.
In neutral with clutch out the input shaft(in the transmission) is spinning at the same RPM as the engine, this is why you can't just push shifter into any gear without pushing in the clutch first, Neutral is a gear, and it spins like all the other gears, it just doesn't spin the output shaft(driveline).

Your issue reads like there is a problem with the output shaft/gears in the transmission.

I assume you have drained it and refilled it once since the flood?

 

Forgot to mention that the shifter can now be pushed into gear without having to use the clutch, but it still grinds and goes nowhere. Yes I drained and replaced the trans oil before i even tried to use it.

 

May need to be cleaned up.
Grease up the throw out bearing mounting area, the input shaft housing may need some.
As been said drain all the fluids, trans, t/c, diffs, none are water tight and if the truck was under water for any length go time all the hear fluids may be diluted.

Also, grease up the u-joints if you have grease fittings, if not watch them because they WILL rust up and seize up or fall apart.

How's the engine oil, did that get water in it too ?

 

lol, yes that would be an important symptom.

Clutch disc is not engaged to flywheel, could be clutch disc splines are stripped hopefully it is not the input shaft, pull transmission and redo clutch.

 

So in the process of taking the transmission off I was in the middle of removing the rear drive shaft when i noticed the front drive shaft spinning as well. I immediately face palmed myself because i realized that I left it in 4 wheel drive when we flat towed it home. So sure enough i remove the front drive shaft and play around with the yokes on the t-case and that's where the noise is coming from. Now my only struggle is getting the stubborn thing off. It's really stuck on there good, any tips of tricks?

 

So transfer case is/was in neutral or simulated neutral, ..............

No, can't help with a tip or trick

 

Ya transfer case is fried, i'm gonna head up to the junk yard and get a new one today. Couldn't get it off yesterday tho hopefully today i'll have better luck.

 

What's a reasonable price for a transfer case? The junkyard I'm at wants $200 for one that's already been pulled

 

Got a transfer case. still have to throw it in but i wanted to check if the 4wd module was even functioning. i ran the self diagnose test which i found therangerstation. LED on the module didnt blink at all which means its either dead or some wire is shorted out somewhere. Any advice?

 

The combination of water plus (and this is just a shot in the dark) an exposed wire or connecter and shorted it frying the module? The plugs are water resistant but not water tight its a long shot but a possibility maybe try a good used module and see if that helps?

 

it depends i mean if water got in there, maybe some dirt or mud did too. i don't know really know I've never heard of this happening but definitely drain the transmission
