Hey guys, I just had my trans blow and dropped it to go get rebuilt. While it was out I was blowing out the Trans fluid lines and can only get air and cleaner to go 1 way. Is there a valve inside the heat exchange that only let's fluid go 1 direction?
Any info is appreciated.

 

If it is still working, there is a check valve in the lines to prevent TC fluid drainback.

 

Perfect exactly what I needed to know. It acted like there was but just wanted to make sure
Thanks so much!

 

LOL, N/P, I think yours is the lone check valve still functioning correctly..........

 

Apparently it's working in some way, it's having a problem though that makes it lock the tc when I drop it in gear in the morning, killings the truck! Ugh, going in on Monday for it. Gonna see if I can't swap for a low stall tc cause I'm hating my medium stall.
