Still fighting the torqshift
I have been having non-stop issues with my tranny. After getting it rebuilt (by some BS shop my warranty company told me to go to) it is starting to leak when parked for more than a day. It generally pisses out about 1/2 to 1 qt overnight when this happens. I crawled under the truck and it looked like the fluid was coming from the pan gasket. Rather than taking it back to the mechanic that decided to take 3 months to fix it last time, I swapped out the gasket myself. This did not solve the problem, and now I am out of ideas. Where and why else could it be leaking from? It is not over filled, I have checked multiple times. Any suggestions would be helpful. I would prefer not to have to hand my truck back over to the incompetent 'mechanic' that 'fixed' it last time. Thanks in advance for any input yall may have.

Next time it's sat overnight check the ATF level before starting the engine. If it is grossly overfilled, and I suspect it might be, the problem is a leaky converter drainback valve. This valve is supposed to keep the torque converter from draining back into the pan.

I understand that you know what you are talking about with these things, but unless I have the wrong dipstick it is not overfilled. On that note, how does one go about troubleshooting a faulty drainback valve?

The way to troubleshoot a faulty drainback valve is to check the ATF level after the truck has sat overnight BEFORE starting the engine. If it is WAY overfilled you have a faulty drainback valve. If it isn't overfilled after sitting overnight BEFORE starting the engine the drainback valve is working fine.
I'm surprised you didn't know this. I told you this two posts ago.

I asked the wife to take a picture of the source of the leak (since I am out of town) and of course I get this in return. At least it gives you a sense of how much my trans will **** in one night.

Mark,
You were right, you did tell me a couple of posts ago... I just didn't catch on to it. I will have to look into that. If that is the case, where exactly would the trans be leaking from? would it be coming out of the vent tube? At this point, I am curious as to where it could be coming from as much as what the cause is.

If the level is high enough it can come out of the vent on top. It can also come out of several different gaskets or seals, depending on which one has failed. If you clean the trans the next time it leaks you can see where it comes from.

Sorry for the late reply. Apparently the military thought I had better things t do than work on my truck for a couple of weeks. I just got back and had a chance to look at where the fluid could possibly be coming from. However, on my quest for answers, I stumbled across something that didn't seem right. Is the vent tube on top of the trans supposed to be connected to anything? I know that it used to be open before my trans was rebuilt, but now there is a new, much longer, tube that is connected to my transfer case (right above the transfer case motor). This doesn't seem right to me, but I figured I would at least ask the question before I toss more fluid into my truck so that I can take it back to the shop that built and installed it.

I have been trying to locate some sort of diagram to show the mechanic where he went wrong so I can get it fixed without coming out of pocket. I would assume that would have some sort of detrimental effect on the tranny...not just whatever seal decided to fail due to it.

I have not been able to find anything regarding a blocked vent tube, much less one connected to the transfer case... Does anyone know the possible damage caused by this. Obviously developing leaks in one, but could there be anything more serious?

I wish you were closer, I would love to look at it for you.
The vent tube shouldn't be connected to the transfer case. Did you do what Mark asked, and the fluid level is correct both cold and hot?
