Nissan Micra Automatic Transaxle Assembly - Torque Converter Install (AT-54)
AT-54 final assembly; inspect converter hub for groove/seal damage, pour approx 2 liters (2-1/8 US qt) ATF into converter housing, install inhibitor switch.
This is a single page (AT-54) from a factory service manual's Automatic Transaxle (AT) section, covering the final steps (41-48) of the transaxle assembly procedure. It instructs the technician to inspect the torque converter for damage, checking the converter hub for grooves from hardened seals and the bushing contact area (step 41); lubricate the oil pump lip seal and converter neck before installation (step 42); and pour approximately 2 liters (2-1/8 US qt, 1-3/4 Imp qt) of automatic transmission fluid into the converter housing (step 43), illustrated by figure SAT672. Step 44 covers installing the torque converter into the converter housing, with a bolded caution not to scratch the front cover oil seal. Remaining steps direct applying sealant to the drain plug threads and installing it (45), installing the inhibitor switch to the transaxle case (46), adjusting the inhibitor switch per On-vehicle Service (47), and verifying that the manual lever operates smoothly (48), illustrated by figure SAT406. The page was uploaded to a 1990 Nissan Micra gallery and is consistent with a Nissan service manual format, though no year, model, or engine applicability is stated on the page itself.
