Hang in there, nobody is shooting at you, and this can be fixed.
Whining to me, sounds like air in hydraulics.
Does it sound like a power steering does when it gets low on fluid?

Does it whine in Park?

I know you have done this, but have you checked the fluid level after you drove it?

Somebody here with more TH400 experience than me let us know if there are any band adjustments.

Not the same as a hydro pump whine...I have that right now too, while steering and when I hit the brakes because of the hydro-boost. Power steering pump is on its way out.

I can tell its coming from the trans, it's obvious. Does not whine in park. Fluid level is fine. I wish I had a gauge to check pressures with....
 
The tranny pump whines like any other pump when its ****ed. I don't think there's anything else that whines in there. You won't ever hear clutches slipping.

Do you have crankshaft endplay?

Where I'm going with this, is during the jack and slash install might have not seated the pump and converter tangs right. And bolted up to the engine loads the pump and crank. It will take the tranny pump out first, then the thrust bearings on the crank, then the crank.

Need to check those things more asap than the main line pressure.

As my father used to say when I crawled in muddy up to the eyeballs, having pulled up a half dozen trees with my winch because I was too stupid to look for solid pull points before driving into a hole.
Then, after partially digging out, making a deadman pull, getting through the bog, discovering that the road did not go though, getting stuck again going back, arriving home about 2 in the morning, he would look at me and grin.

And say: "But look at all the fun you had"
I swear, if it had been anyone but him, I would have shot him dead on the spot.

Strange part is, I was having fun. I just could not see it. Today, I wish I could do it again.

This transmission problem is going to turn out the same way.
You pulled out the tranny and rebuilt it.
Finally got it installed, and it ate its self.

Now, you are going to have to pull it again and start over.
Thats the bad news.
What little good news is, that all the bolts will come out easier, almost all the dirt and grease is gone so it will be a clean removal, you know just what to do this time to get it out, and you will find exactly what went wrong.
That has got to be bugging you right now.
I know its bugging me.......

But, you will find out, you will fix it, and you will get it back in.

And, you know what? Something else might go wrong!!

But, look at all the fun you will have.........!

And when you finally get it going, and its shifting great, you can do like I have done a few times in my life when something fought me for a long time, and it took 5 or 6 tries to get all the bugs out.

You can walk up next to it, make sure no one is around, get real close, grin at it, and say: " I beat you, you bastard!"
Maybe its just a chunk of metal, and does not know you said it, but you'll know, and that is what counts.
 
Bummer man, check your PMs for ideas. Also, demon has a good thing to check too, make sure you have a 1/16" - 3/16" gap before you bolt your converter up to the flexplate. If not the converter isn't seated all the way, or something isn't assembled right.

You'll figure it out, and you'll learn more because of it.
 
The torque converter was mounted/seated properly, that was one thing I made sure of. Gap was right where it should be. Ill be working on the rest as soon as I'm not too pissed off to look at it.
 
I don't blame you, I can't stand doing something twice. Which is why I am so slow doing it the first time. Make sure you figure out not only what happened, but why it happened, so you don't have to pull the tranny a 3rd time. But make sure you pull the pan first to check, although if it was something else it may be too late if your oil is like glitter. Sorry man.
 
After googling th400 pump whine, I'm almost certain I know what it is. A dumb ass brain fart on my part. Which makes this 1000x's worse. When I pulled the pump halves apart, I didn't take it to a trans shop to have it properly aligned with the band clamp thing to go back together. I read about doing that, knew I was supposed to...but still didn't do it. I had thought about just getting a new pump too...bleh.

New pump is $170 at Summit. :doah:
 
Two tricks to align the pump halves at home.

1 - before you put the forward clutch drum in the tranny, just drop the the pump into the case upside down (with no seal). It will align itself that way so you can torque the pump cover bolts. It's easy and free if the trans is out and vertical. Be careful prying out out of the case though.

2- buy a couple huge hose clamps, like a two 6" hose clamps or something. Then screw them too each other. You can tighten them around the pump to align the halves before you torque the pump cover bolts. Super cheap, maybe $4 total?
 
Dude, that is impressive. Given the number of miles, that is an amazing amount of metal.

Of course, the military has always been known for its ability to break things.

The good news, if there is any, is that you will be able to see what was wrong fairly easily.
That much wear should show right up.
Like you said, I'm betting on the pump. Whatever it was had to start grinding right from the start.
A slipping clutch or even a bearing would not produce that much that quick.
Only something that was turning as long as the engine was running would be likely to do that.
 
You remembered to blow out the coolant lines right?
Could there have possibly have been residual funk in the tranny cooler and lines reeking havock on the new tranny?
I'm sure you did, but it came to mind.
 
damn. i just found this thread and read all 10 pages of it. sucks about the trans man, had me thinking for a min there about rebuilding my own TH400 here at home. after the last page though, the $600 for a local shop to do it and warranty it sounds pretty good.
 
Don't let my failure discourage you from giving it a shot. TH400 is fairly simple, buy the book, take your time and it's doable.

If I had my own covered shop/place to work and didn't have to worry so much about tying up a buddies driveway or yard for weeks at a time, I'd probably have pulled it again and done it myself. I just got sick and tired of fuuckin with it to tell the truth. :haha:

i must have missed the thread but what ended up happening with the trans situation?

i thought i read in one thread you were looking at buying a complete aftermarket unit (b&m i think...)

I haven't done anything with it yet. I've just been driving it around on post....no 3rd gear keeps me at 45mph tops and an iffy reverse keeps me on my toes as far as parking. :haha:

I have a few options as far as fixing it. The B&M, but that's money- About $1600 or so. I can drive it the 15 miles on a 65mph highway to the shop at my 45mph top speed, pay them ~$1k to fix it, road test etc and have a warranty. Or I can pull it myself, again, and take it to them to fix pay ~$500 and get no warranty. This particular shop won't warranty unless they do the pull, rebuild, do the re-install and road test etc. I get that, no big deal.

The warranty doesn't mean much to me, because after January or so, the truck is never gonna be within 2800 miles of of Georgia again. I'm leaning towards taking the trans to them for a bench rebuild. I bought a forward drum with 34 element sprag already installed, from folkenheath. Per his recommendation, I'd like to get some Alto Red Eagle frictions as well as a torrington thrust bearing for the case. I could take all that stuff to the shop along with the trans and ask them to install it.

Whatever I do will have to wait till the beginning of December anyways. That's when the money comes in.
 
gotcha... how long after your out before you make a run for the west coast?

(i'm gonna assume about a week after the tranny gets finished)
