Transmission fails to engage when vehicle is cold. We wait a moment for the transmission fluid to build more pressure and then it seems okay. No official remedy yet... at 223k it may be sent to the boneyard rather than the shop. LOL. Great van!

My van has problems engaging in first gear when starting from park. Once its been on the highway and warms up it does fine.
