The ASE A2 Automatic Transmission/Transaxle test has 45 scored questions in three content areas, plus 10 unscored questions, and you get 75 minutes for all 55. Diagnosis dominates: transmission/transaxle diagnosis is 26 questions (57.8%), more than half the test. In-vehicle maintenance and repair is 12 questions (26.7%), and unit removal, inspection and installation is 7 questions (15.6%). The diagnosis area covers torque converter automatics, dual-clutch units, CVTs and hybrid drives, and a large share of its tasks are electronic: scan data, circuits, control modules and OBD II code rules. Questions are four-option multiple choice, including Technician A / Technician B items, symptom-to-cause items and items built on a wiring diagram or an apply chart. A pass plus documented work experience certifies you for 5 years, and A2 is one of the eight tests for Master Automobile Technician.
01The test specification
The ASE test specification for ASE A2 Automatic Transmission/Transaxle splits the 45 scored questions across three content areas. ASE adds 10 unscored questions for research, and you have 75 minutes for all of them. Each area links to five free questions.
| Area | Content area | Scored questions |
|---|---|---|
| A | Transmission/Transaxle Diagnosis | 26 (57.8%) |
| B | In-Vehicle Transmission/Transaxle Maintenance and Repair | 12 (26.7%) |
| C | Transmission/Transaxle Unit Removal, Inspection, and Installation | 7 (15.6%) |
| Total | 45 |
02What is the ASE A2 Automatic Transmission/Transaxle test?
The ASE A2 Automatic Transmission/Transaxle test is one of ASE's certification tests for cars and light trucks. It covers automatic transmissions and transaxles of every current kind, including torque converter units, dual-clutch units, continuously variable transmissions and hybrid or electrified drives, from diagnosis through in-car service to removal, overhaul and reinstallation.
It has 45 scored questions and 10 unscored ones, 55 in all, and you get 75 minutes. Every question is multiple choice with four options, (A) to (D). The unscored questions are there so ASE can gather statistics for future tests, and you cannot tell which ones they are, so treat every question as if it counts.
Passing is one half of certification. ASE also asks you to document relevant work experience, and its study guide says suitable vocational training can be credited toward it; the details are at workexp.ase.com. The study guide does not publish a passing score. Once certified, you hold the certification for 5 years, and you renew it with a shorter recertification test, which for A2 is 23 questions in 30 minutes.
A2 is one of the eight tests, A1 to A8, that ASE lists for recognition as a Master Automobile Technician. The full picture is in how Master Technician status works.
03What does each content area cover?
Area A: Transmission/Transaxle Diagnosis (26 questions)
The task list splits this area into three groups. The general group starts with identifying what kind of transmission you are working on, confirming the concern, checking service history and bulletins, and checking fluid type and level. It also covers the OBD II rules: what has to happen before a trouble code sets or clears (permanent codes included), how the malfunction lamp behaves, and running the monitors to prove a repair.
The mechanical and hydraulic group is road testing, noise, vibration and shift feel, fluid loss and fluid condition, line pressure testing, the torque converter's stator one-way clutch and its lock-up clutch, working from hydraulic diagrams and flow charts, and the auxiliary pumps or accumulators fitted to transmissions on stop/start engines.
The electronic group is the largest, with 13 of the area's 28 tasks. It covers electronic pressure control, electrical tests of the lock-up clutch, circuit and network faults, the charging system and battery as they affect the transmission, telling a transmission fault from one in the engine, transfer case, ABS or driver-assist systems, scan data and bidirectional tests, programming and setting up control modules, meter tests on sensors and solenoids, and electronic shift selectors and indicators.
Area B: In-Vehicle Transmission/Transaxle Maintenance and Repair (12 questions)
These twelve tasks are the work you can do with the transmission still in the car. They cover shift linkage and cables and the range sensor, external seals and gaskets, the driveshaft yoke and drive axle joints, pans, and the cooler and warmer circuit with its thermostats, bypass valves and lines. Inside the pan you inspect the valve body, torque its bolts in the correct order, and check accumulator and servo bores. Electrically you test solenoids, sensors, connectors and control module inputs and outputs. The list ends with powertrain mounts and changing fluid and filters, including units with no dipstick.
Area C: Transmission/Transaxle Unit Removal, Inspection, and Installation (7 questions)
This area has 23 tasks for seven questions, in three groups. Removal and installation covers the checks while the unit is out (rear main seal, dowels, flexplate, converter bolts and pilot, crankshaft end play), seating the converter fully into the pump, flushing or replacing the cooler, routing everything correctly on reassembly, and updating software and running relearns afterward. Disassembly and assembly covers the pump, differential bearing preload, shaft end play, bushings and thrust washers, planetary gear sets, the case, the valve body, chains, belts and pulleys (as in a CVT), and the final drive. Friction and reaction units covers clutch packs and their clearance, air testing clutches and servos, one-way clutches, and bands and drums.
04What kind of questions are on it?
ASE's A2 study guide has eight sample questions, and they lean hard on diagnosis. Several start from a complaint and ask what could cause it: weak acceleration from a stop that is normal at higher speed, slipping only when cold, harsh upshifts, or fluid that overheats while the shifts stay normal. Each answer depends on knowing which component is active in that condition.
Two samples hand you a document to work from. One is a wiring diagram for a CVT's control solenoids with lettered points, and you pick the fault location that explains the symptom. Another is a clutch and band apply chart for a five-speed unit, and you work out which component explains a missing gear. Practice reading apply charts until you can say, for any gear, what is holding and what is driving.
There is also a procedure question (how stored codes should be cleared after a repair) and a Technician A / Technician B item about checking fluid level on a transmission with no dipstick. In A / B items, each statement is judged on its own, and both can be right. The method is in how to answer Technician A / B questions.
Reading traps
The A2 samples have no EXCEPT question, but ASE uses the format elsewhere and flags it with a warning line. Watch the conditions in the stem: cold versus hot, from a stop versus at speed, one gear versus all gears. A cause that would affect every gear cannot explain a fault in only one.
05Where should your study time go?
Area A is 26 of 45 questions (57.8%), so more than half your study time belongs to diagnosis. Areas A and B together are 38 of 45 (84.4%). Area C has 23 tasks but only 7 questions (15.6%), so treat overhaul as breadth: know what each measurement (end play, clutch pack clearance, bearing preload) is for and what a bad reading means.
Inside area A, the electronic group carries the most tasks. Be comfortable with scan tool data and bidirectional tests, voltage drop and resistance readings on solenoid and sensor circuits, and the OBD II code-setting rules. On the hydraulic side, know what line pressure tests and lock-up tests tell you, and how a stator one-way clutch failure shows up.
Use the task list as a checklist: mark each task you could explain, then study the rest. ASE says every question represents one or more tasks. Pace: 55 questions in 75 minutes is about 1 minute 22 seconds each, and chart or diagram questions take longer, so do not linger on the short ones.
06Registering, retesting and recertifying
You register and pay through ase.com. ASE charges a $34 registration fee per order plus $62 for each test, so A2 on its own comes to $96. Each extra test in the same order adds $62, not another $96. ASE sets the registration and scheduling dates, so check ase.com for the current dates and fees before you book. The full breakdown is in ASE test fees and registration.
The test is delivered on screen. ASE offers a free demo of its testing platform at ase.com/free-test-drive, and the study guide notes two language aids: a Leer en español button that shows each question and its options side by side in Spanish and English, with no separate registration, and a Spanish/English pop-up glossary available during all ASE tests. More on the format: how ASE tests work.
If you do not pass, ASE makes you wait 30 days before you can take the test again. Spend the month on area A first, since it is more than half the scored questions.
After you pass, the certification runs for 5 years. To renew it you take the A2 recertification test, 23 questions in 30 minutes; you are eligible for it only after passing the full certification test once.
