To check the fluid level on the Ultramatic trans in the 55 Packard should the level be checked with the engine off or,warmed up with engine running and trans in neutral or park? Old timer said off and cold. Posted on: 2017/10/19 0:42

The service manual describes what to do, packardinfo.com/xoops/html/downloads/servicemanual5556/Sect07_TwinUltra.pdf Posted on: 2017/10/19 7:50

Shop manual says warm engine at curb idle, selector in "N". Posted on: 2017/10/19 7:51
