I checked the valvebody gaskets I had in the trans again and found that no hole in the seperator plate was covered, so that shouldn't be the fault.
I called the tech support of Transgo and the guy was very helpful.
I told him the results of the pressure test and he found them kind of strange.
He also said that the pressure valve has no effect on the problem that I have.
He wants me to do additional pressure tests at 1500 rpm in OD and D to see if the pressure rises.
I also called a GM dealer about a new pressure valve. They want over 60 bucks for it. I saw it online for 9$ somewhere. Crazy germans!

If anyone has ideas please share them.

Thanks, Alex

I am going to type this very slowly.

INSTALL THE PROPER GASKETS


When it says V that means valve body.
When it says C that means case.
Just because holes weren't covered doesn't mean diddly.
They may not correspond with passages either in the case or valve body.

stu, I understand you.

I'm glad I found this mistake and of course I will install the correct gaskets. Maybe that was the problem, hopefully. But I'm not quite convinced.

700R4 has two different sets of valvebody/case gaskets. The set you need must have the holes near the back of the case for the auxiliary valve body. If you installed two "V" gaskets, you will have many hydraulic problems.
I stand by my statement regarding the pressure regulator valve.
The trans will work with it ground off, but it will work fabulously better with the land intact.
Try contacting transmission shops for a distributor name for the parts Transtar sells. Then you can get the Sonnax valve.
Also Sonna has a 800 number. 800-843-2600.

Ok so you aren't convinced wrong gaskets will cause any problems.
If I am correct in my assumption. Why would manufacturers go to all the trouble of making different gaskets for the same transmission?
In fact why have any gaskets at all?
Why not just dig out the old tube of silicone and make your own?
Smear it all over. As long as no holes are covered, no sweat.
Why even a gasket on the pump, or pan?
Just like Brylcream. A little dab'll do ya.

Now, now; play nice.
This trans stuff is not so obvious to everyone....

[stu]

I am playing nice. He won't listen.

stu, like I said I'm glad I found this mistake and I will install them correctly.
Of course the mfgs make different gaskets not just for the fun of it.
You guys helped me a lot so far. Please don't misunderstand my saying of being not convinced.
I will see what happens when I put it together and make another test.
