C6 fluid leak
Hey all,
I have a question about a tranny fluid leak. How high can you mount your oil cooler, if you mount it too high can it cause the transmission to lose fluid out of the overflow?
I have my cooler mounted in front of the radiator towards the top. I am still running the cooler in the radiator in line with the Aux. cooler. I lose fluid but it comes out of the overflow.
any suggestion, appreciated.

What are you referring to "out of the overflow?" Radiator engine coolant overflow tank? What year truck?
You should be able to mount it as high as you want - even on the roof if you really wanted to. As long as there are no leaky connections, the oil will stay in the cooler. The converter circuit has a check-valve to prevent fluid drain back.

The overflow on top of the trans. is where the fluid comes out.
I thought since the trans holds about 11 quarts and the remote cooler is sitting so high that some fluid would creep back into tranny and cause it to run out of the overflow.
If that is not it, then could I be overheating the fluid and causing this condition?
It is approx. the same amount of fluid everytime. I will refill it then drive, next morning same amount of fluid again.
Any help......thanks.

I've never seen an auxiliary cooler thah held more than a quart or so. There is plenty of room for that in the transmission housing, even if it were to drain back. Check the band servo housing cover. If it's leaking, it will leak the same amount every time you stop for a while. Also a leak in this area will look like it's coming from the vent.
