97 Silhouette (Venture)

Morning sickeness, its pregnent. Ok it's not with child, but the symtom is called morning sickness. There are two causes I have found. One the filter is partially blocked andthe fluid old and nasty. fluid thins out as it warms up andthen flows easier. Fluid change. Second cause: There is an internal leak in the tranny that is allowing the fluid to drain out of the torque convertor over night and it takes a few for it to refill when engine started. One way to check is check fluid level a few minutes after you turn the engine off. It should register about an 1-2" over the full mark. The check it first thing in the morning. If it is a lot higher on the stick you found the problem

Awesome info! I decided to a fluid/filter change. There was some metal chunks in the bottom of the pan and everything was covered with a black like film. I am hoping the drain valve your talking about was just gummed up, allowing the torque converter fluid to drain out overnight, since it would only happen in the morning. That combined with a dirty filter and fluid, maybe its fixed. Kinda concerned with the metal chunks though!?! I'll let you know in the next couple of days if this improved it.

Metal chunks or flakes? There is a big difference. If chunks start planning on replacing the box, or scrape the car.
