904 Rebuild

I rebuild/refresh mine(my personal winter-beater trannys)for next to nothing. I have a stack of cores. No race trannys though. Just basic transportation with a TF2, and 2500ish TC. I reuse as much as possible.Call me sick, I dont care. That 904 is barely more complicated than a 4 course meal.Take it out in the AM, back in before supper.
At one time I had 4 spares ready to go.
