No vacuum modulator on this transmission. It is instead electronically controlled.
I strongly recommend a good electronic transmission diagnosis - this will help determine if your problem is electrical and can be fixed without too much trouble, or if it is an internal mechanical concern.
It's not burning transmission fluid, I put Lucas in it but haven't really run it enough to go through, any ideas I am leaving for Wisconsin Tuesday, would like to go up there and have it fixed if possible. Just wondering what you think about it making it.
