TRE uses the highest quality of parts available. We don’t cut corners or use cheaper parts like some shops in an attempt to boost profits. Those cheaper aftermarket parts just aren’t as high of quality as the genuine parts from Mitsubishi. There are cheaper seals, synchros, hub & sleeves and bearings but you won’t find them being used in the transmissions that we build. We know better and we want your transmission to function at its best.
