gracias por colaboracion Vmalejandro, efectivamente hemos realizado esa prueba y el problema solo lo hace en algunas oportunidades.
da la sensaciòn de que desde la 3a a la D a veces quedara como en neutro entre un cambio y otro es decir; suelta la 3ra y queda en neutro, da unos tirones y luego entra la D.
como si algùn sensor o algo impidiera al paso suave. ahora despues de la D, cuando empieza a desacelerar todo lo hace bien y suave.
la caja no patina de N a R la toma inmediatamete y con fuerza, asi tambièn de N a D, el bajar un cambio cuando uno quiere adelantar y pisa a fondo el acelerador, tambien lo hace bien y con fuerza, en D levanta hasta los 180 km/hora sin problemas.
El nivel del aceite esta ok, nunca se enciende la temperatura del aceite y no existe ningun còdigo de falla (check engine).
el scanner a la caja de cambio en la mitsubishi no arrojo ningun còdigo de falla, asi tampoco la ECU del motor, por lo tanto la falla es aleatoria.
la hace con el motor frio o en caliente; se revisaron los conectores y las lineas del cableado de la caja y todo esta OK.
entonces que Chu...... podra ser. ya qyue en la Mitsubishi no cahan mucho y quieren que les dejemos el montero para seguir buscando algo que no saben ademàs de cobrar quien sabe cuanto $$$$, por lo que mejor lo retiramos y continuamos el viaje con cuidado.
Saludos,,, y se agradece toda colaboraciòn.

En nivel de aceite en caliente quedó bien?, lo otro es que hagas el re-learn" de la Ecu, para el del 98 en adelante indica lo siguiente (pero debe ser parecido)
PLEASE READ THIS FIRST *
The following general procedures are to be used if driveability problems are encountered after power loss or battery has been disconnected. These procedures may provide an aid in eliminating these problems.
To reduce the possibility of complaints, after any service which requires battery power to be disconnected, vehicle should be road tested.
COMPUTER RELEARN PROCEDURES
Vehicles equipped with engine or transmission computers may require a relearn procedure after vehicle battery is disconnected. Many vehicle computers memorize and store vehicle operation patterns for optimum driveability and performance. When vehicle battery is disconnected, this memory is lost. The computer will use default data until new data from each key start is stored. As computer memorizes vehicle operation for each new key start, driveability is restored. Vehicle computers may memorize vehicles operation patterns for 40 of more key starts.
Customers often complain of driveability problems during relearn stage because vehicle acts differently then before being serviced. Depending on type and make of vehicle and how it is equipped, the following complaints (driveability problems) may exist:
* Harsh Or Poor Shift Quality * Rough Or Unstable Idle * Hesitation Or Stumble * Rich Or Lean Running
* Poor Fuel Mileage
These symptoms and complaints should disappear after a number of drive cycles have been memorized. To reduce the possibility of complaints, after any service which requires battery power to be disconnected, vehicle should be road tested. If a specific relearn procedure is not available, the following procedure may be used:
Automatic Transmission
* Set parking brake, start engine in "P" or "N" position. Warm-up vehicle to normal operating temperature or until cooling fan cycles.
* Allow vehicle to idle for one minute in "N" position. Select "D" and allow engine to idle for one minute.
* Accelerate at normal throttle position (20-50%) until vehicle shifts into top gear.
* Cruise at light to medium throttle. * Decelerate to a stop, allowing vehicle to downshift, and use
brakes normally. * Process may be repeated as necessary.
Manual Transmission
* Place transmission in Neutral position. * Ensure emergency brake has been set and all accessories
are turned off. * Start engine and bring to normal operating temperature. * Allow vehicle to idle in Neutral for one minute. * Initial relearn is complete: process will be completed during
normal driving.
