GM 4L60E Transmission Valve Body Separator Plate 1993-94. NEW Transgo separator plate for the 1993-1994 4L60E, (46-PLT-94) The stock plates wear out very quickly in these vehicle, even after 20,000-30,000 miles you'll notice excessive wear from the check balls. Once these plates start wearing you will slowly start to lose shift quality, this can eventually lead to transmission failure. This new Transgo plate is made from tougher metal and is also zinc plated, to make it a very durable item. This plate fits all 4L60E's from 1993-94. Please look at my other items more great deals on shift kits, torque converters and other transmission parts.
