There should be a vent tube just above the in and out oil fittings on trans. It may be hard to see if trans is installed in vehicle.
There's only one type of 400 turbo.
i need an exploded view of a turbo 400 transmission? there is a site with trans schematics tcsproducts.com
the 400 turbo is made for more pulling that's whats in my 85 gmc 2500 its just a heavy very expensive transmission.
the older style turbo 400 has a point on one side of the pan in back of the transmission
The 350 turbo is a good transmission but the 400 turbo will take more abuse.
Trans must have excess pressure built up inside. Is the vent working?
yea u can,
That should be a 400 TURBO.
175 without converter
no
Turbo 300, Turbo 350, Turbo 400 and 700R4 are the first ones that came to mind.
If the transmission pan is square in shape then it is a 400 Turbo. If the pan has 1 corner that is in an angle and not square then it will be the 350 turbo.
