TOYOTA VOLVO A40 SERIES (A40 A41-A43D A43DE AW70 AW71) transmissions – ATSG (Automatic Transmission Service Group)

TOYOTA/VOLVO A40 SERIES (A40/A41-A43D/A43DE AW70 AW71) transmissions – ATSG (Automatic Transmission Service Group). The A40 “Series”of transmissions are covered in this manual. In the teardown and assembly section we are using an A43D transmission. We refer to the different valve body configurations where applicable. Although the A40 and A41 do not have the overdrive unit, the assembly is very similar.

The A40 series transmissions are found in Toyota and Volvo vehicles. The units have minor differences and use different gaskets and seals. The Volvo unit may be refered to as the BW55, Not to be confused with the A55 (Tercel). We have illustrated the gaskets for the various valve bodies in a seperate section in this manual. This section also shows valve body disassembly.

There have been many gasket and seal changes on these models. We advise you to check the gaskets from the original unit, and compare them with the replacement gaskets to ensure that correct gaskets are installed.

When diagnosing the A40DE, be sure to determine whether it is an electrical complaint or a transmission mechanical complaint, or both. If the computer is not operating, the transmission should be able to shift manually.
