If I don't see fluid spewing out the cooler line after 2 mins I shut it off.

At this point I may throw in the towel, pull the trans and have a pro look at it

 

maybe it's been asked...are the pump gears in correctly?
how many quarts did you put in before it overflowed out the vent?
which cooler line are you pulling
are the pump halves torqued?
do you have the case to pump gasket in correctly not blocking any passages

to fill the case enough to flow out the vent, you should be like 20+ qts

 

I removed the pump gears and reassembled them exactly as they came out (dimples facing up). See pics above in thread



Cooler line is removed at the trans at the pressure (front) port, not squirting out there so that rules out a clogged cooler line



I torqued the pump halves to 18 ft lbs.



The gasket was in good shape and actually stuck to the pump, I left it as is (not covering any passages).



I will try the new filter out tonight and see if it makes a difference. If it doesn’t I’m pulling the damn thing out and dropping it off at a local performance trans shop to have it gone through.

 

For whatever reason, the pump is not picking up fluid out of the sump.

 

so...you're confirming you put 20+ qts in it?

 

Let's recap. I put 4 quarts in the converter and installed the converter into the trans, confirming it was fully seated by measuring. I put 4-5 quarts in the pan, started the engine, and put another 4 quarts in it right away. It then started to overflow. I am unsure of how much of the fluid in the converter made its way into the case when the engine was started.

Does that answer your question?

Trans is out and going to a local performance shop to be gone through next week. I suppose the silver lining is that I'm great at pulling this thing out now. 2 hours from a running vehicle to a trans on the floor.

 

so 12 total quarts on a fresh trans?

Keep us informed on what the shop finds

 

Wait...?

Did you ever get a gauge on the main-line tap?

You had the transmission removed, the pump assembly removed, and the the pump assembly separated.

Did you take any time to look at the valvetrain in the pump assembly?
Or at the very least (Most Importantly)... the pressure regulator valvetrain?

Should a DIYer like yourself suspect that the transmission is unable to create any fluid pressure or flow...
Whilst observing no filter through pump gear-set obstructions, with a gear-set that is at least unbroken (whether or not clearance is correct)...
The next VERY crucial component in this system that will ultimately factor if ATF will flow to the next scheduled destination (the Torque Converter via the rest of the pump valvetrain) or if the ATF will be exhausted.

The pump pressure regulator valve and spring!

While I do not expect this to actually be occurring... How easy of a time would it have been should only the pressure regulator spring be broken, or the pressure regulator valve be damaged?

We could have helped to guide you through this or direct you to an existing thread of benefit.
My question is: Did you look at the pump valvetrain?

I feel badly... you did the most difficult part of this job (For me anyway... maneuvering that heavy "F"ing unit out and back in the vehicle).
Then you gave up...

MaroonMonsterLS1 had just started to try and help you out.
He is one of the good people here that after working all day at his transmission business, he comes home and gives out FREE transmission information to people in our community that may not have another avenue to pursue before the $$$ starts disappearing.
Then he goes back to work the next day and charges people for that same information.

Sometimes I feel as if many of the people here do not have any idea that US BUILDERS on this website are actually doing "Just That"
"Just That" meaning... Providing Free information from experience and knowledge gained from how we make our livelihood
The very thing, that we need to survive in life and have an income... We just hand it out like candy on Halloween.

Please do not get me wrong. I am not mad.
I feel badly for you. You gave up too soon.
The information we give out here, is much more valuable than (I think) most of you realize... And we are happy to do it! So take it... and don't give up!

 

I do appreciate the help on here. There is no doubt that there are very talented and knowledgeable individuals here that are willing to help, and the fact that they do it for free is just the cherry on top. For that I am grateful as there have been more times than I could count where some info on this forum saved my ***.

However there comes a time when one has to weigh the options of continuing to dive into the problems, versus the value of my time. Based on my current workload and the schedule that I set for myself there is not a whole lot of value in tearing it apart while the summer goes by.

Once the transmission is back in the truck and working, I’ll be sure to post up on what the issue is so that this thread is of use to others down the road.

 

Update – it runs and drives! Currently NA with the charge piping off to shake it down, it’s a dog since I have the turbo timing (11-12 degrees) in it right now but I’m just happy it moves under its own power.

Picked up the trans from the shop with the Rav4 2500HD




















Immediately loaded it up with junk to take to the scrap yard



Turns out one of the valve body gaskets had shifted when I installed the HD2 kit and it was blocking some passages. The gasket had some impressions where check ***** had obviously pushing into the gasket material rather than the hole in the gasket, resulting in massive internal leakage. The shop confirmed that the pump looked fine and clutches looked good. Although it wasn’t fun to pull this thing out a couple times, I think it was worth it to have a pro go through this $200 80E and give it a clean bill of health.

 

First I'd like to thank all the pros who give out free information that is not vague and not meant to scare people into not touching their transmissions. I'm grateful because this is exactly what I used to build my 4l80E.

Of course there a some non professionals who won't work on transmissions themselves, but instead will hopefully seek out the pros that provide good, clear, free information to build the transmissions for them. I hope you pros continue to provide free candy and you get customers back in return.

Oh and thanks again for the Halloween candy that I personally have enjoyed so much. This candy made me thinner and my wallet fatter. Hopefully your businesses and wallet will grow as well.
