Information needed: valve body oil passage diagram for a 5R55E valve body.

[Castorized]

Hey folks. Some where out there, I hope, I can find a diagram/schematic for the fluid passage flows for my 5r55e valvebody.. I'm having an issue with mine. Cold I have proper shifting..although it has always been slow to go from park into gear, once in gear it shifts normally. OD light flashed the other day. But before I could pull the code, it went away. Now, when warm/hot it requires atleast 1000-1200 rpm to engage in gear. Any gear. All the same. But has huge shift flare 1-2. And slipping a little bit. Yes fluids are topped up and fresh. Any ideas? But still I am looking for this diagram for reference. Help(?)

Your thread was moved into the transmission section. Check the 5R55E valve body rebuilding diary sticky thread on the top of this section for more information. This photo was taken from Glacier991's photo gallery:

Oh PS: also too I had to do a system reset. It would not go into park (just rattled the parking pawl madly) and no gears whatsoever at that time. This issue has popped up a couple times sice I owned my baby. But this I belive is not the same issue.

That might be caused by a failing shift interlock mechanism. There is a TSB on that issue.

Thank yu much Brooklynbay for the quick reply, but moreso I am looking to trace where all the worm passages go to n fro. I would love to figure out if I'm crazy to think that somehow the pressure coming directly from the pump/tc is Geting leaked away when hot, before it reaches it's intended locations... Ya know what's I means? Thx for the help so far

The two main places where leaks occur are from the end plugs, and the valve body gaskets.

Could my pump be on the fritz?? It just occurred to me.... K.I.S.S

If you didn't reset the computer by disconnecting the battery or with a scan tool, the code is still stored in the computer. Restarting stops the OD light from flashing but the code is still stored and the OD light will flash again, may take a little time.
There is no oil flow chart that I know of. You need to do a line pressure test to check the pump.
