In this video the solenoid body of the A604/41TE transmission in Stratus is disassembled, but it applies to other vehicles from 1989 to 2011 such as: Voyager, Neon, Avenger, Journey, Town Country, Cirrus, Eclipse, etc.
First, the disassembly and cleaning of the different parts of the solenoid body are carried out, such as the pressure sensors of the different applications such as: low/reverse, 2/4, overdrive application and underdrive application, reviewing the different parts. , the resistance of resistors, pressure diaphragms, oring rings and conductive plate, as well as measuring the resistance of the solenoid.
With this maintenance the condition of the solenoid body will be verified and its reconstruction will be possible.
Electrical diagrams of operation and resistance values shown in the transmission rebuild manual are presented.
The details of the disassembly and testing of the solenoid body and the solenoids, gaskets, springs, pressure switch capsules, diaphragm are presented, the solenoids are marked to prevent the position from being lost since two are normally open and two are normally closed.
Ultrasonic cleaning of all parts of the solenoid body is performed by immersing them in solvent and pulsing them.
The plane that sits in the transmission housing is rectified to reconstruct its flatness and the sealing of the joint is optimal, the resistor welds are verified so that there are no cold welds and their resistance is measured.
With the help of a high impedance meter, it is tested that the solenoids are not crossed or shorted, the use of the equipment is explained.
With the help of an adapter, a regulated source and a hook ammeter, the operation of each of the solenoids is identified, identifying whether it is open or closed, the position in the body, the application it powers and the current it consumes, to be able to document it since this information is not found in the service manuals and have references.
The cleaning of the pressure sensor plungers is presented and tests are carried out with air pressure to observe how they close and the assembly of the solenoid body begins, identification of the oring rings on the solenoids.
Verification tests are performed on the solenoid body, solenoid resistance, resistors and pressure switches.
