i have a 1985 rx7 that i just got running good, it has auto tranny.well after i got engine running i was excited.but when i filled up the tranny fluid it was all good till i went down the road and it started smoking like a bonfire,well then i turned around and went home and the tranny fluid which i just put in was almost empty but it does not leak with engine in park only under pressure,well i guess it was shooting tranny fluid on my exhaust and creating all that smoke(the weird thing is that alot of the smoke was coming out of exhaust pipes? could exhaust leak be sucking in the smoke? thanx
