Re: Transmission Part Identification

Hey look!
A vacuum modulator!

The pipe is the dip stick. Shows you the fluid level in the trans.
If your helper is talking about a small metal tube (1/4 inch) that runs close to the red one, that would be the vacuum line from the intake. Modulator needs full time manifold vacuum.

Look on the other truck again. The modulator might be on the back pointing rearward. It’s a turbo 350 if it is.
The trans in your pic is a turbo 400.
