MEC3130 Automatic Transmissions

Advanced · 1 credit · TMT - Trades, Manufacturing and Transportation

Description: Students develop knowledge of automatic transmissions and transaxles and skills in diagnosing and executing minor automatic transmission and transaxle repair requirements.
Prerequisite: MEC1110: Pneumatics & Hydraulics
Parameters: Access to automatic transmission diagnostic tools and support resources. Note: Customer work must be supervised and checked by a certified technician.
Supporting courses: MEC2140: Transmissions/Transaxles

Outcomes The student will:

1 demonstrate established safety and care procedures when working with automatic transmissions and transaxles
- 1.1 demonstrate knowledge of and follow established laboratory procedures
2 identify the parts of a torque converter and automatic transmission or transaxle, and determine the path of power and the shifting control operation in each gear setting
- 2.1 describe the operation of a torque converter
- 2.2 compare the internal structure of a lock-up converter and nonlock-up converter
- 2.3 identify the parts of a transmission assembly by naming pieces on a diagram or parts of a disassembled unit
- 2.4 using a hydraulic flow diagram, explain the unit engaged and shift process for each gear position
- 2.5 interpret shifting characteristics resulting from differentiated inputs; e.g., high road speed, pulling heavy loads, throttle valve position
3 inspect, diagnose, service and complete a minor repair to an automatic transmission and transaxle assembly
- 3.1 use the service manual and a road test to determine probable causes of noted conditions
- 3.2 complete diagnostic procedures developed from service inquiry, which may include linkage adjustments, pressure testing and further road testing as well as partial disassembly of the transmission
- 3.3 perform a stall test according to manufacturer’s specifications
- 3.4 list parts for required repairs
- 3.5 inspect transmission/transaxle oil level and develop an assessment of its odour and colour
- 3.6 change transmission fluid and filter as described in the appropriate service manual
- 3.7 check unit for oil leakage and determine a cause for loss of oil
- 3.8 repair a fluid leak
- 3.9 evaluate the condition and adjustment of linkage
- 3.10 locate and correct a transmission linkage or band adjustment, where required
- 3.11 remove, clean and reinstall a transmission valve body assembly
4 perform a service and repair procedure on an automatic transmission
- 4.1 remove, repair or replace an automatic transmission assembly
5 demonstrate basic competencies
- 5.1 demonstrate fundamental skills to:
  - 5.1.1 communicate
  - 5.1.2 manage information
  - 5.1.3 use numbers
  - 5.1.4 think and solve problems
- 5.2 demonstrate personal management skills to:

  - 5.2.2 be responsible
  - 5.2.3 be adaptable
  - 5.2.4 learn continuously
  - 5.2.5 work safely
- 5.3 demonstrate teamwork skills to:
  - 5.3.1 work with others
  - 5.3.2 participate in projects and tasks
6 create a transitional strategy to accommodate personal changes and build personal values
- 6.1 identify short-term and long-term goals
- 6.2 identify steps to achieve goals
