General Repair Information: Transmission

• Do not run the engine and do not tow the vehicle if the transmission pan is removed or if there is no transmission fluid inside the transmission.
• Always clean the connection points and the area around them first, and then loosen them.
• When installing the transmission, make sure the alignment sleeves are correctly seated between the engine and transmission.
• Place removed parts on a clean surface and cover them so that they do not get dirty. Use foil, paper or a lint free cloth.
• Only install clean components: Remove the replacement parts from their packaging just prior to installing them.
• Carefully cover or seal unpacked components, if repairs cannot be performed immediately.
• With the transmission removed, secure the torque converter so that it cannot fall out.
• After installing, check the fluid level and fill, as necessary. Refer to AUTOMATIC TRANSMISSION FLUID LEVEL, CHECKING AND ADDING .
• Capacities. Refer to CAPACITIES .
