CAUTION

CAUTION: The pressure adjusting bracket is under spring tension by the pressure
regulator and switch valve springs.

g. Remove the center screw from the adjusting screw bracket. Temporarily remove
one of the long screws holding the three valve body castings together and install
it in place of the center screw (Figure 2). This will help to hold the bracket in
place when removing the upper and lower screws. Remove the upper and lower
bracket screws while holding the adjusting screw bracket. Remove the center
screw. Save the OE switch valve spring, line pressure screw and adjusting bracket
for reassembly. Discard the OE pressure regulator spring.

Ream Switch Valve Bore

NOTE: This bore requires the use of tool kit 22771A-TL13 (not included
in this kit). See page 8 for details on standard Sonnax bore preparation.
These piloted reamers do not require a reamer guide.

1. R
 eam bore with stepped reamer
22771A-RM13
a. Insert reamer into bore until chamfered cutting tip contacts
inner bore opening. Using a speed handle, ream bore clockwise at one to two turns per second. This reaming operation
should take approximately 1 minute.
b. With low air pressure and reamer still in bore, blow chips
out of bore.
c. Turning clockwise, remove the reamer from the bore.
Clean the remaining chips from the bore.

08-27-15 SC-48RE-IN
Page 2

Remove and save the OE retaining pin.
 OTE: It is recommended to use a Dremel® #194 drill bit or .120" diamN
eter drill bit to remove some of the swaged aluminum over the top of
the retaining pin. Damage could occur to the enclosed .096" drill bit if
used for material removal.

2. Ream Bore
a. Securely clamp the valve body to the bench.
b. Soak the bore and reamer with cutting fluid.
c. Insert the pilot on the self-guiding reamer into the retaining pin end of the detent bore until the cutting chamfer
contacts the face of the bore (Figure 3).
d. Use a speed handle to turn the reamer in the bore. The reaming action should be clockwise in a smooth and continuous
motion, 60-120 RPM.
e. Continue reaming until the reamer cutting chamfer passes
fully through the opposite end of the detent bore.
f. Using low air pressure, blow the chips free prior to removing
the reamer.
g. To remove the reamer, turn clockwise while slowly pulling
outward on the reamer.

3. Install Detent Sleeve & Pin (Figure 4)
NOTE: The Sonnax sleeve is designed as a slip fit, and is secured by
drilling through the sleeve with the tool kit drill bit and reinstalling the
OE retaining pin. However, it is highly recommended that Loctite® (or
equivalent) be used with the sleeve.

a. Secure the Sonnax sleeve in the detent bore using Loctite®
retaining compound per the manufacturer’s directions.
b. The sleeve should be pushed in until the face is flush with
the face of the ball end of the detent bore.
NOTE: Before drilling, it helps to use the retaining pin as a center punch
and make a slight indentation in the sleeve to hold the drill bit on-center
and prevent the drill bit from walking off and making the pinhole in the
casting larger.

IMPORTANT! This adjustment is critical on 2005-later models which use a
Transmission Throttle Valve Actuator (TTVA). The ECM needs to see the TTVA
CAUTION rotate a set number of degrees. At .627", the TV shaft will move 52°. Depending
on the tolerance in the software, this may set trouble codes if the adjustment is
out of range. After installing the valve body in the vehicle, reset the TTVA by performing a
Key On Engine Off cycle for 30 seconds. Turn ignition key off. Now the TTVA will be reset.

Generic F-Tool Bore Reaming Instructions
1. Bore & Reaming Preparation
a. Clean the bore thoroughly in a solvent tank.
b. Generously lubricate the bore and reamer with cutting fluid (i.e.
Mobilmet S-122, Lubegard® Bio-Tap, Tap Magic™, etc.). For
best results, provide a continuous flow of water-soluble cutting
fluid (i.e. Mobilmet S-122) during the reaming process.
c. The reamers should be turned using a low RPM, high-torque
air drill regulated to a maximum of 200 RPM.
d. Examine the bore after cleaning for surface finish, debris and
burrs. Flashing and burrs on the exit side of land and in bores
must be carefully removed. A small piece of Scotch-Brite™
material attached to a wire and powered with a drill motor
is ideal for the task. Scotch-Brite™ is a very abrasive material
and all residual debris must be cleaned to ensure particles do
not migrate or remain imbedded into the surface. Post cleaning
involves several progressive steps with solvent on a lint-free rag.

.)

CAUTIONS AND SUGGESTIONS:
•	 Turning the reamer backward will dull it prematurely.
•	 Pushing on the reamer will result in poor surface finish and
inadequate and sporadic material removal.
•	 Never use a crescent wrench, ratchet or pliers to turn the reamer.
•	 A dull reamer will cut a smaller hole. Reamers can be sharpened,
but should only be done by a professional tool sharpener. Actual
life of a Sonnax reamer before resharpening or replacing averages
50–70 bores.

2. Bore Reaming
Use the associated “F-Tool” kit and VB-FIX reaming fixture as illustrated below to ream the bore. See specific reaming instructions for
each bore on page 2 of this booklet.
NOTE: If more than one reaming procedure is needed, follow specific
instructions given with associated Sonnax part/kit to ensure correct reaming process is completed.
