So we finally dump tranny oil in my bro's buggy and it takes about 4 qts and starts dripping between the TH350 and the 203 adapter plate. Major bummer since dropping the 203/205 isn't just a bolt in with this chassis. When we took it apart, it turns out the back face of the trans was really warped and the adapter plate wasn't very flat either. This thing never really had a chance of sealing up. Don't take this stuff for granted, throwing a straight edge on the mating surfaces would have told us all about this before we even put the gears in the boxes. Now the adapter is turned flat and the trans is hand filed flat and it's all good so far.
