I've been having this problem and have posted this before but I thought that someone else may have run into this issue since that time. Nobody seems to know WTF is going on. When I first start it in the morning, as soon as I let go of the key the whole damn truck lurchs and there is a metallic bang. Do the think that the starter solonoid (sp?) is sticking. 2 dealer's told me that they have never heard of this.[:@] It banged really bad this morning.

 

It almost sounds like the starter motor is loose on the bellhousing...It's just a guess, but I expereinced a simular sound when one was loose on an RX-7 I had once...More like a clunk as I remember

 

Sounds to me like it has to be something with the tranny[&:]

 

Let the dealer have it overnight so they can experience it for themselves. Does it only happen when it is cold, or does it do it when it is warmed up too?

 

it does it only when it's cold.
