OUR 4-STEP APPROACH TO RELIABLE TRANSMISSION REPAIR

Our process minimizes downtime and delivers long-term performance and reliability, ensuring your operation doesn’t miss a beat.

Diagnostic Testing

Every transmission undergoes comprehensive testing before teardown to confirm symptoms and failure points. When needed, HDT can also perform diagnostics while the transmission is still in the machine to reduce downtime.

Complete Disassembly & Inspection

After removal, all clutch packs, valve bodies, shafts, and internal components are disassembled, inspected, and measured for wear. Any failed parts are documented, and a full quote is provided before repairs begin.

OEM-Spec Repair & Reassembly

Worn or damaged components are replaced with OEM or OEM-grade parts. Valve body and pump assemblies are carefully repaired or replaced, and units are reassembled to strict torque specifications and cleanliness standards.

Final Quality Check & Customer Report

Every unit goes through a final QA review to ensure reliable performance. Customers receive a detailed report outlining the failure analysis, completed repairs, and post-repair test results.
