Ive heard that on cold mornings you want to put trans in N and let it idle like that. Does that really work and does it circulate fluid throughout?

 

Does circulate fluid........only good way to warm the tranny is to use it.

 

Agrees^^

The stock Valve body does not flow fluid in Park to certain areas of the transmission. If you put the tranny in N, the valve body will open ports, flow fuild, and warm up the tranny sooner.

 

hi
install a tfod -diesel vb kit from transgo and it will flow in park plus extend the life of your trans by a big margin !

 

Stomp the emergency brake and put the tranny in gear it will warm the WHOLE transmission.

My tranny guy told me that my TC was leaking back to the tranny and that I could put it in neutral for a few minutes after cranking to get the TC refilled.
I can tell the difference. In the past when I cranked and put it in R, the truck wouldn't hardly move. Now, I crank, put it in N, wait a minute or so, put it in R and it starts rolling back. Been doing that for over a year. Truck shifts real good towing or non-towing.
