Hi, i'm in need of some advice. My transmission started leaking out of the front seal while my girlfriend was driving it. I would have just replaced the seal but she continued to drive it home. It would only go about five mph at open throttle so I know the transmission was very low if not empty. I would rather replace the transmission instead of rebuilding it due to cost. My question is would the aw4 be a direct swap for my tourque flight 904? I searched the forum but didnt find a deffinate answer or someone who had done it in the past. Thanks in advance.
