95 TSI Dies In Reverse

When i shift into reverse (auto tranny) from a stop , my rpms shoot way down to about 500 or less. Sometimes the rpms will dive really low and then shut off. This sometimes happens on a hard stop after a turn while in drive. (like goin into a parking spot.) My check engine light is on. Does anyone have any Idea whats goin on here?

Thanks

Travis

did you check the code on the engine light

maybe torque converter??¿
