my transmission shifts real hard especially the first time It's not the fluid but I was told it may be a vacuum line. the problem is I dont know which vacuum line is for the transmission I recently put this motor in a 84 mustang so I may have something backwards and cant figure it out PLEASE HELP!!!

rec.autos.makers.ford.mustang

On the newgroups at

The transmission modulator needs adjusting,try a transmission shop.
It shouldn't cost more than $20.00

The vacuum modulator is located on the rear passenger side of the tranny. You should see a vacuum line there, and it will be hooked to a steel line which runs up the top of the tranny to the rear of the intake manifold. It should be hooked to the vacuum tree, or somewhere up there where it can get manifold vacuum.
