How you'll learn
Fully 100% online training on the SEIUM campus, with downloadable material, recorded classes and a dedicated technical tutor. No fixed timetable: students progress at their own pace within the intake, which makes it possible to combine study with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is ZF-Testman, Allison DOC, Jaltest, TEXA IDC5, Bosch ESI[tronic], in free, academic or evaluation versions. Tests are studied using real procedures for stall and line pressure tests, reading of parameters and fault codes, and road tests with data logging. Assessment is continuous per module plus the final integrative project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
Explain the hydraulic and electronic operation of an automatic gearbox.
Use diagnostic equipment to read fault codes and live parameters.
Carry out functional tests of pressure, stall and gear change.
Diagnose faults from operating symptoms.
Plan the intervention, repair and adaptation of the gearbox.

Frequently asked questions
The programme consists of 300 hours in total, spread over 3 to 5 months. That is between 10 and 15 hours per week on average, compatible with a full-time job.
You work with ZF-Testman, Allison DOC, Jaltest, TEXA IDC5, Bosch ESI[tronic]. Free, academic or evaluation versions are used, and the tutor indicates the free alternative where one exists.
An SEIUM own diploma upon passing the continuous assessment and the integrative project. It is in-house training, not an official qualification from the Ministry.
Yes. Modules passed in a course or postgraduate diploma in the same area are recognised towards the advanced programme. Check the recognition policy when you enrol.
