Transmission & Clutch Repair
Transmission problems can stop a truck or machine completely. Mondak diagnoses and repairs slipping, delayed or harsh shifts, units that won't move, clutch engagement problems, leaks and control faults. We work on manual and automated truck transmissions, Allison automatics, and powershift and hydrostatic drives in equipment from manufacturers such as Funk and ZF. Diagnosis includes fault codes, fluid condition, pressure checks and road testing.

THE MONDAK APPROACH
Diagnose first. Repair with purpose.
We check fluid level and condition, read codes and test pressures before recommending repair. Clutch problems are checked for adjustment and linkage issues first.
Some control and linkage repairs can be done in the field. Transmission rebuilds and clutch replacement happen in the shop.
