Appears I have the Torque Converter flow back in my C-4 that others have talked about and fluid runs out of my overflow tube after sitting a week or so. What have others done to modify/lengthen the tube to deal with this. Pictures would be great.
Thanks.

The reason your C-4 pukes fluid after a week or 2 of sitting is because of a faulty check valve in the tranny. The only way to replace the check valve is a COMPLETE dismantle.I just put up with it.

Extending the vent tube is an idea. Ford Explorers (for example) have their vents at the very rear of the transmission. The tube for them goes all the way up to the topmost bellhousing bolt and then loops back down and stops just above the transmission shifter.
Obviously Ford's intent was to vent the transmission while not allowing water to get in it if the vehicle was driven into deep water off-road. But no reason you couldn't loop your own vent tube similarly. I don't have a C4 handy and don't remember the vent design but I suspect attaching a hose to it might be a little tricky.
