What is the torque spec for the transmission drain plug?

10 - 20 N·m (1.0 - 2.0 kg-m, 7 - 14 ft-lb), with sealant applied to the thread of the bolt.

What torque is specified for the position switch retainer bolt?

2.5 - 3.9 N·m (0.25 - 0.4 kg-m, 1.8 - 2.9 ft-lb), with sealant applied to the thread of the bolt.

Which parts must always be replaced during a case component overhaul?

Parts marked with an asterisk (*) must always be replaced — the diagram marks the oil seals with this symbol.

Where is sealant applied when assembling the case?

To the mating surface at the welch plugs, to the mating surface of the clutch housing and transmission case, to the drain plug threads, and to the position switch retainer bolt threads.

This is a scanned page (MT-4) from a factory service manual's manual transmission (MT) section, titled 'Major Overhaul – Case Component.' It presents an exploded-view diagram of the transaxle case assembly, identifying the clutch housing, transmission case, input shaft bearing retainer, speedometer pinion and its adapter, oil seals (marked with an asterisk indicating they must always be replaced), welch plugs, oil channel (with a note to pay attention to the direction of the oil groove), straight pin, O-ring, position switch and switch retainer, drain plug, and boot. Torque specifications are given in N·m (kg-m, ft-lb): 16–21 N·m (1.6–2.1 kg-m, 12–15 ft-lb) for the input shaft bearing retainer and case bolts; 10–20 N·m (1.0–2.0 kg-m, 7–14 ft-lb) for the drain plug; and 2.5–3.9 N·m (0.25–0.4 kg-m, 1.8–2.9 ft-lb) for the position switch retainer bolt, with sealant to be applied to the bolt threads. Sealant application points are indicated for welch plugs and the mating surface between clutch housing and transmission case. The figure reference is SMT879. No specific year, model, or engine is stated on this page.
