WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 GMC Yukon XL, 2003 GMC Yukon, 2003 Chevrolet Tahoe, 2003 Chevrolet Suburban, and 2003 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
- Install the checkballs (1-7) into the valve body.
- Install the valve body to the transmission case while simultaneously connecting the manual valve link to the manual valve.
- Verify that the manual valve link (3) is installed properly to the inside detent lever (1) and the manual valve (2).
- Install one bolt (M6 X 1.0 X 47.5) hand tight in the center (1) of the valve body to hold it in place.

Important: When installing bolts throughout this procedure, be sure to use the correct bolt size and length in the correct location as specified.
- Do not install the transmission fluid indicator stop bracket and bolt at this time.
Install but do not tighten the valve body bolts which retain only the valve body directly.
Each numbered bolt location corresponds to a specific bolt size and length, as indicated by the following:
- M6 X 1.0 X 65.0 (1)
- M6 X 1.0 X 54.4 (2)
- M6 X 1.0 X 47.5 (3)
- M6 X 1.0 X 35.0 (4)
- M8 X 1.0 X 20.0 (5)
- M6 X 1.0 X 12.0 (6)
- M6 X 1.0 X 18.0 (7)
- Install the manual detent spring.
- Install but do not tighten the manual detent spring bolt.
- Install the transmission fluid pressure switch.
- Install but do not tighten the valve body bolts which retain the transmission fluid pressure switch to the valve body.
NOTE: Refer to FASTENER NOTICE in Cautions and Notices.NOTE: Torque valve body bolts in a spiral pattern starting from the center. If the bolts are torqued at random, valve bores may be distorted and inhibit valve operation.
- Tighten the valve body bolts in a spiral pattern starting from the center, as indicated by the arrows.
Tighten
Tighten the bolts in the sequence shown to 11 N.m (97 lb in).
- Ensure that the manual detent spring is aligned properly with the detent lever.
Tighten
Tighten the bolt to 11 N.m (97 lb in).
- Install the TCC solenoid with a NEW O-ring seal to the valve body.
- Install the TCC solenoid bolts.
Tighten
Tighten the bolts to 11 N.m (97 lb in).
- Install the internal wiring harness to the valve body. The internal wiring harness has a tab (1) on the edge of the conduit.
- Place the tab between the valve body and the pressure switch in the location shown (2). Press the harness into position on the valve body bolt bosses (1,3).
- Install the TCC PWM solenoid (1) to the valve body.
- Install the TCC PWM solenoid retainer (2).
- Install the transmission fluid indicator stop bracket (1) and bolt (2).
Tighten
Tighten the bolt to 11 N.m (97 lb in).
- Connect the internal wiring harness electrical connectors to the following components:
- The transmission fluid pressure manual valve position switch (1)
- The 1-2 shift solenoid (2)
- The 2-3 shift solenoid (3)
- The pressure control solenoid (4)
- The TCC PWM solenoid (5)
- The 3-2 shift solenoid (6)
- Install the transmission filter. Refer to AUTOMATIC TRANSMISSION FLUID/FILTER REPLACEMENT .
