ASE A2 Automatic Transmission practice test
The A2 test spans road-test diagnosis, hydraulic and electronic controls, and off-vehicle rebuild work. Expect shift-quality scenarios, pressure-test logic, and converter questions — practiced here with an explanation after every answer.
When a TCM detects a serious electrical fault and enters failsafe (limp-in) mode, a typical strategy is:
How the A2 test works
45 scored questions
+ ~10 unscored research questions
75 minutes
computer-based, at a test center
$62 per test
plus one $34 registration fee per order
Valid 5 years
then a shorter recertification test
ASE does not publish a fixed passing percentage — scores are scaled. Around 65–70% correct is the commonly cited range; aim above 80% in practice so you walk in with margin. The certificate is issued once ASE verifies your required work experience.
What the A2 test covers
The official task list for A2 Automatic Transmission/Transaxle breaks down into these content areas — the practice bank above draws from all of them:
- General diagnosis — fluid condition, road-test symptoms, pressure tests, and noise isolation
- Hydraulic and electronic controls — valve body, solenoids, TCM inputs, and shift quality
- Torque converter and lockup clutch operation and diagnosis
- In-vehicle and off-vehicle repair — clutch packs, bands, planetary gearsets, seals, and endplay
- Maintenance — fluid and filter service and cooler flow
Frequently asked
- How many questions are on the ASE A2 test?
- The A2 test has 45 scored questions plus about 10 unscored research questions, with a 75-minute time limit.
- Does A2 cover CVTs and dual-clutch transmissions?
- The task list is built around conventional automatics, but electronic-control diagnosis concepts carry over. Check the current ASE study guide for exactly what the task list includes.
- What is the hardest part of A2?
- Most technicians point to hydraulic circuit logic — knowing what a pressure test result or a slipping range tells you about which circuit or clutch is at fault.
