Does anyone know much about these transmissions? Specifically, what years came with overdrive? I thought they were all 3 speed TH-400 basically, so I wrote them off for my project, but I saw an '85 on Ebay listed as 4spd. I'm trying to figure out what year donor car I need to watch out for. I refuse to use something without overdive. I'm assuming the Toranado is the same too?
So basically the large GM front wheel drives from 82-85 were 4spd overdive trannys. I just found an 83 Toranado for sale on my way home today, so that would be the perfect donor.
Might not use that after all though, there are some problems with using it RWD. Have to do some more research.
