AUTOMATIC TRANSMISSION TEST DEVICE PROVIDED WITH AUTOMATIC TRANSMISSION FLUID SWITCHING MECHANISM, AND AUTOMATIC TRANSMISSION TEST METHOD.

摘要

The automatic transmission test devices of the prior art, wherein a changeover valve is used in an automatic transmission fluid (ATF) switching mechanism, reduce oil performance due to mixing ATFs. An ATF switching mechanism (16) of this automatic transmission test device is provided with: a first supply-side coupler (17) disposed at the leading end of a first oil supply pipe (14) of one oil tank (10); a second supply-side coupler (18) disposed at the leading end of the other oil tank (11); a supplied-side coupler (19) that is disposed on a pallet (2) on which an automatic transmission (1) is mounted, and joins the supply-side couplers (17, 18); an oil supply pipe (34) that links the automatic transmission (1) mounted on the pallet (2) with a third coupler (19); and a coupler-linking mechanism (20) that moves the first coupler (17) or the second coupler (18) to the position of the third coupler (19), thereby joining the first coupler (17) or the second coupler (18) with the third coupler (19).
