211) After rebuild and reinstallation of an automatic transmission the technician may need to: OA. adjust the crankshaft position sensor angle. OB. adjust the throttle position sensor. C. perform a brake pedal posit the seam procedure. OD. perform a shift relearn procedure.

## Step 1<br />This problem is about the steps a technician might need to take after rebuilding and reinstalling an automatic transmission in a vehicle. The options provided are:<br />A. Adjust the crankshaft position sensor angle.<br />B. Adjust the throttle position sensor.<br />C. Perform a brake pedal position calibration procedure.<br />D. Perform a shift relearn procedure.<br /><br />## Step 2<br />Each of these options represents a different step that a technician might need to take after installing a new automatic transmission. However, the most common and necessary step after installing a new automatic transmission is to perform a shift relearn procedure.<br /><br />## Step 3<br />The shift relearn procedure is necessary because the transmission control module (TCM) needs to learn the new gear ratios and other parameters of the newly installed transmission. This process allows the TCM to accurately control the transmission's shifting.
