Hi friends. Can someone give me some light about the transmission secondary pump? Does this pump is only active when the engine is turned off and is use only for towing? Will this pump can become engaged (active) at any moment when the engine is RUNNING, as an auxilliary pump. Thank you in advance. By the way the transmission is a 722.361, and I am still curious about a spring I found in one of the port of the secondary pump. If you have any information about the origin of this spring, please let me know.

Thanks!

Darrel
