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,
no
175 without converter
That should be a 400 TURBO.
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.
