ASE lists the Medium/Heavy Truck Drive Train (T3) test as a 50-question test (40 scored plus 10 unscored research questions) with a 60-minute time limit, delivered by Prometric. Scoring is criterion-referenced, meaning a passing score is set by ASE against a defined competency standard rather than a fixed percentage. The official content areas are Clutch (28), Transmission (33), Driveshaft & Universal Joint (18), and Drive Axle (23). Certification requires two years of relevant work experience (training can substitute for up to one year), each T-series test is taken individually, and T3 is part of the Master Medium/Heavy Truck Technician path. This free practice bank provides 100 selected-response items across all four official content areas.

Frequently Asked Questions
How many questions are on the ASE T3 Drive Train test?
ASE lists the Medium/Heavy Truck Drive Train (T3) test with 50 total questions, of which 40 are scored and 10 are unscored research questions that do not count toward your result. This free practice bank provides 100 selected-response items so you can drill every content area more deeply than the live test length.
How much time do I get and how is ASE T3 scored?
ASE allots 60 minutes for the T3 test, delivered through Prometric. ASE scoring is criterion-referenced, which means a passing result is determined against a defined competency standard set by ASE rather than a fixed percentage or a curve against other test-takers.
What does ASE T3 cost and what are the eligibility requirements?
ASE registration for a single specialty test such as T3 is approximately $59; confirm the current amount when you register. To become certified you also need two years of relevant hands-on work experience, although an approved training program can substitute for up to one of those two years.
What are the official ASE T3 content areas and weights?
ASE T3 covers four areas: Clutch Diagnosis & Repair (about 28 questions), Transmission Diagnosis & Repair (about 33), Driveshaft & Universal Joint Diagnosis & Repair (about 18), and Drive Axle Diagnosis & Repair (about 23). Transmission and Clutch together make up the majority of the scored questions.
What content area should I study most for ASE T3?
Transmission Diagnosis & Repair is the largest area, followed by Clutch, then Drive Axle, then Driveshaft & U-Joint. Weight your study toward systematic diagnostic strategy on countershaft/range/splitter and AMT transmissions and on clutch release/adjustment, because most T3 questions test how you isolate a fault, not just part names.
Are there any 2026 changes to the ASE T3 test?
As of 2026 ASE continues to list the Medium/Heavy Truck T3 test under the standard T-series structure with a 60-minute limit, Prometric delivery, and criterion-referenced scoring. Always verify the live ASE test page and your myASE account for the current registration fee, scheduling, and any content-area updates before you test.
