The valve body of the A604/41TE transmission in Stratus is disassembled, it also applies to vehicles from 1989 to 2011 such as: Voyager, Neon, Avenger, Journey, Town Country, Cirrus, Eclipse, etc.
The valve body is disassembled, checked and tested. Removed TR (transmission range) gear selector, described park position to remove transmission valve body, removed shifter spring, 2/4 accumulator, 2/4 coupling rubber , manual valve and screws to separate the transfer plate, contamination is observed.
Various parts are identified: separator plate, transfer plate, valve body, thermostat, overdrive check valve, filter, plastic check balls, marked as 2 underdrive, 3 low reverse, 4 reverse and the transfer plate cylinder 5 overdrive.
The valves are removed and identified (TCC throttle valve, low reverse switch valve, converter clutch control valve, converter clutch switch valve, solenoid switch valve and throttle valve) cleaning is done to be able to test, it is done a polishing on the surface as it presents marks due to pressure and dirt from the oil, it must be done with care not to scratch the cavities, the valves show damage due to oil contamination.
The flatness is tested with a calibrated 1.5 thousandths shim and ruler, observing that there is no deformation.
The valves are installed to the valve body lubricating with ATF (Automatic transmission fluid) automatic transmission oil, so that they do not run dry and to be able to do the tests, the care for the installation of the valves in the cavities is mentioned.
With a Sonnax vacuum pump and pressure gauge, the different valves are tested to check their tightness, with information from Sonnax, the procedure and precautions are described to avoid errors in measurements, it is verified that only one valve is in good condition, the others have leaks that prevent their operation, you have to get another valve body, which will be cleaned and the procedure described above to be able to test it.
The recovered valve body is shown, it is contaminated and the considerations that must be taken when a part is found in these conditions are mentioned, as well as the original valve body of the transmission is compared against the recovered one.
The measurement of the characteristics of all the springs is made and a table is made to document them, it is measured; spring length, diameter, wire diameter and number of turns.
The valve body is tested with the Sonnax equipment. It is verified that it is in good condition.
The valve body is assembled and the torque is given, with the data in the manual, with the precautions and the order, the 2/4 accumulator is assembled with the spring and Teflon ring from the Transgo shift kit, it is put the selector lever, TR, pawl of the lever together with the other accessories. The TR and the temperature sensor are tested

Hola buenos días. Soy Veracruz. Requiero ajustar el motor de una Town country 3.8 1999. Dónde creé que pueda conseguir el manual?
Muchas gracias por compartir información que es de mucho provecho para los que vemos su canal saludos y bendiciones

Excelente video, podria compartir por favor la ubicación de su taller
Buenas noches excelente videos perdón dónde se encuentra ubicado
Buenas noches. Buen contenido. Le falto la prueba de los pistones de la valvula interruptora de solenoides. Es muy importante para este tipo de cuerpos de valvulas . Podriamos desir que es la principan faya, de esta transmision o familia de transmisiones que cuentan con este tipo de valvula. Saludos.
Porque no le entrala reversa a trasmisión A604 de doge gran Caravan

@@Arturo_segura si es cierto lo vi tarde, aun no me puse a estudiar como funcionan las cajas automaticas. yo tengo una dosivac 60lt/s no se si alla existe esa marca. para refrigeracion . vos la usas para probar que no tenga fugas las valvulas
Espero me yuden
Buena noches. Cual es el costo de una reconstruccion completa de la transmision para una town country 2003 3.8. Costo en la transmision actual y costo enviando la transmision nueva
