ok so i was supposed to pull my trans today but instead my dad says to just put a couple quarts in it and go .
he says that a transmission man said that sittin in a cruise in like i was or haulin hay heats up the seals causing a leak .
the fix let it sit and cool off and refill
is this true or not.

 

Trucks aren't supposed to leak fluid at any time, cold or warm. Waiting for it to cool off everytime it leaks isn't a good idea. Besides, heat expands things and cold shrinks things, so it would be more likely to leak cold and stop leaking hot.

 

yea i tryed to tell my dad that but i cant get him to listen to me about it
he said as long as i can drive it its good so i guess im just gonna drive it till it fries the trans out and have him pay to fix instead of me

 

i do know that the trans pressure system is thrown off from leaks and will blow that thing up. its cheaper and easier to rebuild if not already blown up

 

When the oil is getting hot it starts to leak if the seal is worn out. Hot oil has a higher fluctuation, so the seal can't hold it inside anymore. This process is not related to "things getting bigger when they worm up" - difference between hot/cold temperatures is not that big to notice it.

 

well we put fluid in it and its not leaking yet
i really think we need to pull the trans and rebuild but he says it runs thats all that matters

ill prolly be back on this thread updatin that my trans smoked itself haha
