I recall reading in FAA Order 7110.65, that it is the responsibility
of the air traffic controller providing Radar Traffic Advisory Service
to VFR aircraft to coordinate transition through Class B, C, D and E
surface area airspace, but I can't find it now:

Perhaps I was thinking of this:

2-1-16. SURFACE AREAS

a. Coordinate with the appropriate nonapproach control tower on an
individual aircraft basis before issuing a clearance which would
require flight within a surface area for which the tower has
responsibility unless otherwise specified in a letter of agreement.

REFERENCE-
FAAO 7210.3, Letters of Agreement, Para 4-3-1.
14 CFR Section 91.127, Operating on or in the Vicinity of an Airport
in Class E Airspace.
P/CG Term- Surface Area.

b. Coordinate with the appropriate control tower for transit
authorization when you are providing radar traffic advisory service to
an aircraft that will enter another facility's airspace.

NOTE-
The pilot is not expected to obtain his/her own authorization through
each area when in contact with a radar facility.


Yes, you were thinking of that, and erroneously expanding it to include
Class B and C airspace. Coordination of a flight through a Class D surface
area by the overlying radar facility is appropriate because the airspace is
small, the flight through it will take only a few minutes, it is typically
surrounded by airspace being worked by the same controller, and the tower
has no responsibility for separation of airborne traffic. Class B and C
airspace is probably at least sixty miles across and may be well over a
hundred, separation of VFR aircraft is required, and the controller at the
point of exit is probably a different person and may be in a different
facility.
