A2 Automatic Transmission/Transaxle Practice Tests

A2 Automatic Transmission and Transaxle – What the Test Covers

The A2 test is 45 scored questions in 75 minutes, and well over half of it is diagnosis. ASE wants to know whether you can find the fault before the unit comes out, which is why pressure testing, scan data and road-test interpretation carry more weight here than teardown procedure.

Content areas and their weighting below come straight from the 2026 Official ASE Study Guide task list. Every question on this site was written against one of these tasks, and the four tests in this subject are weighted to match.

Content Areas on the A1 Test:

• Transmission/Transaxle Diagnosis58% OF TEST
  26 questions — by far the biggest single area on any A-series test. Identifying the unit type (torque converter automatic, dual-clutch, CVT, hybrid or electric drive), verifying the concern, fluid type, level and condition, diagnosis with a DMM, scan tool or oscilloscope, OBD II enable criteria and monitor status, road testing for mechanical and hydraulic faults, noise, vibration, harshness and shift quality, hydraulic pressure testing, torque converter stator and one-way clutch failure, lock-up converter testing, and electronic control diagnosis including sensors, solenoids, modules and bus communication.
• In-Vehicle Transmission/Transaxle Maintenance and Repair27% OF TEST
  12 questions. Shift linkage, cables, bushings and range sensors, external seals and gaskets, driveshaft yokes and axle joints, pans and covers, cooler and warmer circuits including thermostats and flushing, valve body service — mating surfaces, solenoids, bores, valves, springs and retainers — and torquing valve body fasteners in the proper sequence, accumulator and servo bores and pistons, electrical and electronic components, control module inputs and outputs, powertrain mounts, and fluid and filter service with correct type and level.
• Transmission/Transaxle Removal, Inspection, and Installation15% OF TEST
  7 questions. Removal and installation with inspection of core plugs, rear main seal and dowel pins, flex plate condition and indexing, torque converter installation and correct pump engagement, cooler flushing and replacement, mounts, brackets, harnesses and heat shields, scan tool calibration and solenoid or valve body software updates, then disassembly and inspection: fluid pump and drive components, differential bearing preload, input and output shaft end play, shafts, splines and journals, bushings, thrust washers and bearings, planetary gear assemblies, and case bores, passages and vents.
