4r100 DIY rebuild

If you have your ATSG manual, there are some 'air checks' you can do with minimal air pressure that will let you know if things are sealing properly.

You can use a pressure gauge in the test port to check for leaks.

I did have and used a pressure gauge and it did not indicate any leaks all the pressures were with in specs listed in the ATSG manual. After installing the rebuilt accumulator valve body I must have added too much oil back in to the system. I really do not know how much oil it takes since I'm not using the radiator or stock cooler. The dip stick is not easy to see when to much oil is in the system.

On to the good news. Apparently that was the problem this last go round. After draining almost 2 quarts of extra oil I have not had any shift delays or errors show up in the system. 450 miles driven in all types of driving.

Once again thank you every one that had any advise it all helped.
