700r4 fluid level I have a 700r4 behind a 4.8 lr4.
shifts good however I can’t get the fluid level correct. Cold shows way up the dipstick. Crank it up and nothing shows.if I put more fluid in it just leaks out. Eyeballed everything and I only see a slight pan gasket leak.
i do have a trans cooler mounted in front with braided lines to and from. No leaks there.
What is going on?????

Crank what up? ...The engine?
Okay, I am now assuming that you do not know the procedure for checking the ATF level for a THM700-R4 Transmission.
The one and ONLY way that the level can be accurately checked is the following:
-The Engine must be running.
-The Transmission must be in Park.
-The Engine and Transmission must be fully warmed-up to operating temperature.
-The Transmission Dip-Stick must be pulled out of the tube and wiped clean.
-The Dip-Stick must be re-inserted fully into the tube, and remain there for a few seconds.
-The Dip-Stick must be removed again, but making certain that the handle is always up and the bottom tip is always down.
-Then you may look at the ATF level on the Dip-Stick.
This will give you a relatively close "Full" measurement (this is because the Dip-Sticks are often slightly Off in terms of where the Full mark is located).
If you wish to find out how to make certain that the Full mark is accurate...
Please use the search feature of this forum, and you will find the instructions.
Good luck.

Looks like there will be no free advice from me today.
It's not my fault that you were checking the ATF level with the engine off and cold...
Then starting the engine ("crank it up") and wondering why the ATF level changed.
I politely gave you sound advice on how to stop checking the ATF level incorrectly.
If you feel intellectually inferior, and wish to be a baby about it...
You are out of luck and will not get much help here.
If you apologize for being rude (for no reason that I fashioned) and behave in a civil and polite manor...
Then I would be happy to continue trying to help you further.
If not, and you wish to be a jerk; attempting to show intellectual dominance over myself...
You are going to lose, and leave crying.

Perhaps I misstated the issue. I k ow exactly how to check the transmission fluid. That’s why this is such an issue.
I stated the cold level just indicate there’s plenty of fluid.
Once it’s running and warm there is no fluid showing on the dipstick.
if I fill it all I get is a huge leak but upon inspection there are no obvious leaks showing all around the tranny.

You have not said what type of vehicle, that you are referring to.
What is the year, make, and model?
If the vehicle is a four wheel drive Truck...
Then the Transmission fluid may be going into the Transfer-Case.
If the vehicle is a car...
Then the ATF may be going into the engine coolant.
(This may also be happening if the vehicle is four wheel drive Truck).
Inspect the other fluid levels.

Vorteciroc is a Former GM Power-Train Engineer and Delphi Automotive Connection Systems Engineer, so implying that he is unintelligent makes you come across very poorly. I understand that you are frustrated but insulting one of the most respected posters in this forum is not the best way to get help from anyone. My advice is to start over and not be so disrespectful with people who are trying to help you.

Okay, so not a Truck/ no Transfer-Case...
and no ATF cooler being used in the radiator.
So, by process of elimination and your statement that you only see a small leak from the Transmission Oil-Pan gasket...
There are only a few possibilities remaining.
Quite possibly, this is simply the issue at hand (Oil-Pan Gasket).
In order for the Dip-Stick to read "Full" or above (for most Dip-Sticks)...
The ATF level needs to be just above the Oil-Pan gasket level or higher.
Also if the Transmission Vent is restricted or blocked by debris; ATF will leak out with ease.
I would next inspect the vent and change the Oil-Pan gasket (make certain that the Oil-Pan mounting surface is in good condition to seal properly).
Then refill and recheck the ATF level by following the instructions in my first Post in this Thread.

Leaking because it is overfilled!!! Overfill and it will leak from the breather or vent - too much fluid!!!!

Thinking it’s a pinched vent tube I had an aftermarket dip stick and changed it out to stock one that came with the tranny.
The transmission is a remanufactured one now with only around 70 miles on it.
The next issue is how to get to the vent. Gonna be a very tight fit.
that’s what you get from sticking that drive train in that car. But why else would I be here.....

Found the leak!! Well the pan gasket and the vent tube are okay.
the leak is coming from the TV cable. Tightened it and it got worse. Lesson learned!!!.
Should I just replace the seal or change out the whole cable? Do the braided steel cables seal better than the plastic?
don’t want to have to deal with this again.
Thanks

Usually the Boot/ Seal in the Transmission case is all that is needed.
However if the plastic housing of the TV cable is cracked/ damaged/ broken/ Etc...
That can cause a leak and require the TV cable to be changed.
If not, then just change the seal.
