Upon disassembling your T5 gearbox, there are a few things you should look for. There are two versions of mainshafts used in the '85-'95 Mustang 5.0L: needle bearing ('85-'95 GT) and pocket bearing ('93-'95 Cobra). The needle bearing-style mainshaft, which features 15 individual needle bearings in the back of the input shaft, is the most common to pit (arrow) if the transmission is run low on fluid. Astro offers reconditioned needle bearing-style mainshafts at a significantly reduced cost.
