Need Help: Problems with my tranny

[riceburner]

My tranny is doing funny things.

When the car is warm> No problem
When it is cold outside, and I start the car after it has sat for a while, when I move it from park into reverse or any gear for that matter, the car dies. It seems like it goes into the highest gear with no slippage.

When I do get it going, it quickly shifts into the highest gear. Imagine being in overdrive at 30. It even does it when I manually shift it into first. But as soon as it warms up, all the problems go away.

What is happening.

I was planning to get the tranny mod, but want to wait until I resolve this. or is the valve body screwing up and replacing it with the performance upgrade fix the problem. I kinda don't want to go to the dealership because the one near me is a "it doesn't work, we need to replace it."

Has anyone had a similar problem? Any suggestions would be greatly appreciated. Thanks.

Time to fall back on that lovely warrenty. Do you shift with the auto? or drop it into N? Do you mess with the O/D? If so, Your trans is flunked up. Hopefully you got a back up car. Cuz your's will bo out of comission for a while.

Peace.
