TECHNICAL SERVICE BULLETIN
A/T VALVE BODY REPLACEMENT
Model(s): 1986-94 Acura Vehicles
Group: Transaxle
Bulletin No.: ASN 1293-09
Date: December, 1993
SERVICE INFORMATION
Whenever you replace a valve body in an automatic transmission, compare the new valve body with the old one, and inspect them both closely. First, be sure that the new valve body is identical to the old one. Then, make sure all the valves are installed in the new valve body. Not all valve bodies are sold as complete assemblies. For example, some main valve bodies don't come with an orifice control valve. Double-check the valve body the first time, and you may save yourself the time-consuming and frustrating experience of removing and disassembling the transmission a second time.
