The Stovebolt Site Forums The Shop Area Engine Shop trans question

I put a 700 r4 in my truck last winter and when the truck sits for more than a couple of weeks it takes a little cranking to get it primed up. Whenever it gets that way the trans will always spit trans fluid out of the top of the dip stick on to my engine when it fires up. It only does it when it takes some cranking to get it running. Its not really a big deal other than the mess. It does have the original dip stick from the trans which is bent down some but I don't think thats the problem. Has anyone over seen this before?

You're experiencing "converter drainback" where the torque converter partially empties itself into the transmission case. This raises the fluid level far above normal. When it starts, regardless of the length of time cranking, the movement of the gears inside splashes fluid out of the dipstick tube. Have a transmission shop check the valve body to see if the converter "anti-drainback" valve is not seating properly.
