Connector for 4R70W and 4R75E, 1998-UpTranstar now has a replacement for the 4R70W and 4R75E connector. This product matches the fit, form, and function of the OE equivalent, which is no longer available. Other aftermarket connectors have too much clearance to the case, allowing fluid leakage. Look for the âTâ on the connector to denote this aftermarket alternative, available only from Transtar.
