Transmission

[321countryboy]

I have a 1988 chevy k1500. With a 700r4 and it has been sitting for awhile and I tried to move the truck and it wouldn't move. You can see the chassis move when you put the truck in reverse. But it won't move. I also tried to shift it into 4wd and I can't move the shifter it's almost liked the gears are locked up in the tcase. And I just replaced the tranny filter and put new fluid in it.

brakes frozen up ?

seen this a lot over the years . sitting around the pads can rust to the rotors and also shoes bind in the drums.

jack up the wheels and try to spin them by hand and see what happens.

as to the tcase bindup not sure unless its related to the bound up driveline.

Brakes or rear end seized more than likely. Put the transmission in neutral, engine off, and try to turn the rear driveshaft by hand.

If you can wiggle it back and forth, odds are its the brakes. If its seized tight, then more than likely the rear end.

If you did not mention the chassis trying to move, I would have said seized transfer case.

Nope brakes wernt frozen up. I'm thinking gears might be rusted in the tcase cause I drained it an water came out

I think you might have found it.
You can get away with that sort of thing if you keep driving the truck. My old Jeep would have about a pint to a quart of water in the front and rear ends after every hunting season.

In wet years, the transfer case and transmission had some too. But in over 15 years, it never hurt anything.

Because I kept the gears turning and the mix stirred up.
If it sits for a while, the water settles to the bottom, and starts rusting things.

Its still not good for the bearings and gears, because its not as good a lube, but its amazing what they will handle.

Yeah I'm gonna pull the tcase down is there anyway I can maybe get the rust off or loosen up the gears or am I pretty much done

Just depends on the damage. Slightly pitted gears will work with some noise. Shifters can be freed up.
But any rust on a bearing is fatal.

However, lots of companies sell rebuild kits which have the bearings and seals, so it may be salvageable.

BTW, the water in the transmission I spoke of does not pertain to automatics. I found out the hard way.
I was used to water in everything from crossing streams bogs during hunting season.
So, when I got my '79 F150, I never gave a thought to deep water.

After a wet year, I drained all the fluids, including the C6 automatic transmission.

Saw some water in there also. Did not really think about it.
Pretty soon, it started slipping.
I knew a guy who owned a transmission shop, and asked him about it. He said that the water would soak into the brake band liners. Then, when they got hot, it would flash to steam and cause the lining to peel off.

Took a rebuild to get me going again.
