REMOVAL AND INSTALLATION
Removal
1. Disconnect the battery negative terminal.
2. Remove engine under cover and fender protector (LH). Refer to EI-26, "
Removal and Installation".
3. Drain the A/T fluid. Refer to AT- 1 7
.
4. Remove oil pan and oil pan gasket.
5. Check for foreign materials in oil pan to help determine cause of malfunction. If the ATF is very dark, smell burned or contains for-
eign particles, friction material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish build up. Varnish can cause valves, servo, and clutches to
stick and can inhibit pump pressure.
•If ATF contains frictional ma terial (clutch, bands, etc.),
replace radiator and flush cool er line using cleaning sol-
vent and compressed air after repair of A/T. Refer to CO-
40.
6. Remove magnets from oil pan.

• When replacing an engine or transmission you must make sure any dowels are installed correctly during re-assembly.
• Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drive
train components.
• Do not reuse O-rings and copper washers. Refer to "COMPONENTS".
• When turning crankshaft, turn it clockwise as viewed from the front of the engine.
• When tightening the bolts for th e torque converter while securing the crankshaft pulley bolt, be sure
to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-159
.
• After converter is installed to drive plate, ro tate crankshaft several turns to check that transaxle
rotates freely without binding.
• When installing the torque converter to the transaxle measure dis- tance A.
• Check the fitting of the dowel pins when installing the transaxle assembly and the engine assembly.
: Dowel pin
• When installing the transaxle to the engine, align the matching mark on the drive plate with the matching mark on the torque converter.
• When securing the transaxle to the engine, attach the bolts in accordance with the following standard.
HR16DE engine models
(A): A/T to engine
(B): Engine to A/T
• When installing the transaxle to the engine, align the matching mark on the drive plate with the matching mark on the torque converter.
• When securing the transaxle to the engine, attach the bolts in accordance with the following standard. Dimension A: 14.4 mm (0.567 in) or more
