5R55E Question
Have an 04 Sport Trac with the 5R55E in her. Looks like pan gasket is leaking and also looks like the output shaft seal is leaking.
Going to attempt a drain and fill and replace the filter. Sticking with the OEM Motorcraft filter. While replacing the gasket…and possible the seal too. Also, getting a new pan with a drain bolt build in.
Wanted to see if anyone wanted to share opinions on fluid? Think I should stick to Motorcraft Mercon V or think any kind of Mercon V should technically do since it meets spec. Lastly, any suggestions for an additive just to help keep it going? I know that’s prolly a loaded question lol, but figured I’d ask. She has 210K on her. No issues/drivability concerns as far as I can tell.
Thanks for your time, Reddit fam!
