besides the cardboard in the front thing, is there another way to fix this so tranny front seal wont pop out again during extreme cold day, like -30ish/-40ish.

mine popped out and blew the front seal while i was travelling down highway. luckly warrenty covered it all and replaced tranny.

Thanks

Was the truck cold when this happened? Your tranny should run the same as any of ours do once it warms up. It's just the first few miles that are an issue.

 

It should not pop out in the extreme cold. A lot of these trucks are run at extreme cold temps and their seals don't pop out. Blocking the rad will not reduce the cold on start up. Your transmission might have a cooler bypass valve. When the transmission is cold it recirculates the oil back into the transmission bypassing the cooler. This warms up the fluid faster.

 

not that the extreme cold would cause them to pop out, but i wonder how much pressure is built up if the truck is driven 70 mph shortly after it is started on a -40* day.

 

Just for my own curiosity do you warm the truck up for 10 or 15 minutes when it is that cold out or do you subscribe to the 30 second warm up and drive away theory?
