What you expect from the outside. When I received the item, it was clean and appeared to be in good condition. I. Couldn’t use it though because it was the wrong one

Le pondré 4 estrellas por el momento la verdad tenía un poco de dudas sobre el módulo pero llevó una semana con el y el carro se siente genial como nuevo no necesitas programar nada sólo es cuestión de conectar y listo. Espero dure mucho tiempo, los únicos detalles fueron que venía un poco dañado del gel disipador pero espero no afecte en nada (reubique el módulo en la pared de fuego para que aumente más la vida útil se los recomiendo) sólo queda esperar un tiempo y regresó con más comentarios esprero les sirva el mío es un mazda 3 2011 2.5 automático con módulo letra G y funcionó genial.

great service but the TCM was bad

WRONG PART DO NOT BUY
Either this part is Chinese garbage or is falsely advertised, but this part is not compatible with a 2010 Mazda 3 2.0L engine. Left with a permanent check engine light that cannot be cleared, so the car will not pass inspection. Unable to perform an adaptive relearn, so this part is junk. Supposed to come reflashed plug n play and it is not.

El módulo llegó bien embalado y sin detalles físicos. Lo instalamos y el coche encendió sin problemas. Todos los errores y testigos (AT y Check Engine) se apagaron. Ya no da jalones y las velocidades las da suaves. Lo recomiendo si buscas reemplazo directo para el TCM con letra G
