Car needs warm up?

[Addicks]

Hi tgc, I have a 2001 gtz that won't move by itself unless I have to warm it up to a certain temp. Any ideas? Thank you.

Yes i have, and its pink. i have a hunch its the whole transmission itself thats the problem, but i want to know if theres any other reasons that could be.
