Buenas, les cuento que hace un par de semanas cambie el aceite de la transmission a mi rexton rx290, este viene con la transmision BTR M74 Australiana., ademas de esto tenia una fugita de aceite entre la caja en si y un culito que se acopla al transfer.
Lo lleve donde un especialista en cajas y me dijo que comprara el gastek set($400 mas o menos) de la caja porque era imposible conseguir las juntas separadas., necesitaba la que va entre la caja y el culillo que se acopla al transfer y un retenedor que que va entre este culillo y el transfer.
me puse a buscar y las encontre en www.fourgreen.com me costaron $12 y $10, ademas compre el set de filtro $80.
al final lo que no pude conseguir fue el aceite tq95 de castrol, pero analizamos y pusimos el equivalente mas cercano de castrol segun las recomendaciones de un ingeniero de castrol en costa rica. eso si, se le hizo un lavado interno a la caja y con un modificador de fluido antes de poner el nuevo aceite y ademas se saco todo el viejo aceite.
hasta el momento todo quedo muy bien. esperemos que siga asi
adjunto imagenes del set del filtro que consta de la junta y el filtro
ademas venia una hojita con las indicaciones del cambio de aceite en ingles, le trate de tomar una foto pero quedo mal entonces trancribo el dato por si es de ayuda.

SERVICE PREPARATION
1.Clear area around transmission case to pan abutment face to ensure dirt does not enter the transmission.
2.Make sure the working area is clean and free froms dust.
3.The transmission should be warmed to normal operating temperature.
DRAINING THE TRANSMISSION
1. Lift vehicle on host or jack to free working height and support with safety stands.
2. Place countainer (at least nine litre capacity) under transmission to collect fluid.
3.to drain fluid, remove all except the front three pan bolts wich are then loosened graduality to allow the fluid to drain over the rear of the oil pan.
4. Remove the oil pan carefully and drain remaining fluid.
REMOVAL AND REPLACEMENT OF FILTER

REPLACE PAN AND REFILL
1. Assemble new rubber gasket on pan lip. Gasket should be free of any distortion when fited.
2. Fitl oil pan bolts to case and tighten to 4.5Nm (40lbs/ins).
3. Partially fill the transmission with oil. this typically requres approximately four litres if the torque converter is full. Start the vehicule in PARK with parking and foot brake applied and the engine idling, Cycle the transmission gear selector through all gear positions adding AFT until application is felt.
4. Add an additional 0.5 litres when gear application is felt in step three.
5. Fit and tighten fill plug to 30-35Nm.
6. Vehicule then is to be driven between 3.5-4.5 kilometres a light throttle so the engine does not exceed 2,500rpm. This will result in the transmission temperature being between 45=55 degrees celsius.
7. Ensure vehicle is level with engine stopped for at least three minutes. Remove filter plug. the correct level is reached when AFT is aligned with the botton of the fill hole. Top up as necessary.
9. Replace filter plug, clean all remnants of oil residue from the transmission and tighten plug to 30-35Nm.
