Yesterday, I had my transmission fluid changed. Found were black powdery stuff from the pan. My mechanic told me I need a trans rebuild.

I just got the car last November and the PO does not remember changing it in his 3 years of ownership.

I am experiencing flaring at 2-3 shifts when cold. Shifting is fine under operating temp. Also flares 2-3 at WOT. No shifting issues other than that.

VCV input from vac pump is 22" and VCV output after green damper is 10". My vac reading at idle is 10" to the transmission from a T after the green damper from the blue disk. It goes down to 0" at wot.

Do you really think I need a rebuild?

Would a K1 spring kit solve this?

How can I adjust the VCV output to 12" to put it up to spec?

Thanks for your time.
