• Torque converter

• Main control assembly

• All 4 speed sensors (intermediate speed sensor A [ISSA], intermediate speed sensor B [ISSB], turbine shaft speed [TSS] and output shaft speed [OSS])

• Fluid pump

• Front support

Clutch and planetary assembly

3. Disassemble the clutch and planetary assembly. Perform only the necessary steps to remove the CDF clutch cylinder from the clutch and planetary assembly. Refer to WSM, Section 307-01 > Overhaul.

(1). It is only necessary to remove the following:

• A clutch assembly

• T3 thrust bearing and shim

Clutch and planetary container cylinder

• E clutch and input shaft assembly

• Number 3 planetary carrier and number 3 sun gear

• Number 3 sun gear shaft and number 2 ring gear assembly

4. Disassemble the C, D and F clutch assemblies from the CDF cylinder. Discard the CDF cylinder.

5. Assemble the C, D and F clutch assemblies into the new CDF clutch cylinder.

6. Perform the C, D and F clutch pack endplay measurements for proper clearance.

7. To reassemble the clutch and planetary assembly, reverse the removal procedure. Refer to WSM, Section 307-01 > Overhaul.

8. Perform the T3 thrust bearing measurement to set transmission front end clearance.

9. Reassemble the transmission starting at Step 299 in WSM, Section 307-01 > Overhaul.

11. Perform an adaptive learning drive cycle. Refer to WSM, Section 307-01.

NOTE: Advise the customer that this vehicle is equipped with an adaptive transmission shift strategy which allows the vehicle’s computer to learn the transmission’s unique parameters and improve shift quality. When the adaptive strategy is reset, the computer will begin a relearning process. This relearning process may result in firmer than normal upshifts and downshifts for several days.
