Technical issues and repair guidelines

This Mitsubishi-Hyundai family of transmissions is frequently repaired. The distinction between F4A41 and F4A42 units lies in distinct quantity of frictions in packs, and consequently clutch drums of various capacity. The transmission reassembly commonly requires the kit of gaskets and seals, filters and complete kit of frictions. In old cars which went through the oil starvation, specialists change the entire kit of bushings together with usual procedures related to cleaning and reassembly.

In terms of design, the main soft spot of the F4A41 unit is the planetary gear Overdrive, where the needle bearer gets dyed when exposed to overloading. The rear planetary gear and a crown gear also get out of order. This planetary gear was repeatedly updated. In most cases, specialists replace burnt Overdrive package, frictions with steel and bearing discs. The valve body is one of the causes for burning of packages Underdrive and 2-nd Brake. The wearout and clogging of valves and solenoids leads to fluid shortages not only in these packs, but also in the TC unit. The valve body was repeatedly updated and now has modifications with 5 and 6 solenoids.
