RobertISaar Posted June 20, 2009 Report Share Posted June 20, 2009 Hey any one know if a 1986 3.8 will fit a 1991 3.1 auto tranny FWD or RWD? if its a RWD, i'm gonna say no. if it was a FWD, then probably, i'm pretty sure its the same bellhousing pattern i really don't know why you would want to hook up a 86 FWD 3.8 to it though, those motors were dogs...

lumina racer Posted June 21, 2009 Author Report Share Posted June 21, 2009 To save time and money and I have the engine in a park ave and the trans in a bonneville but if I can use the trans in my lumina were the motors going anyway than why do I need the other trans that's in the bonneville Quote Link to comment Share on other sites More sharing options...

lumina racer Posted June 21, 2009 Author Report Share Posted June 21, 2009 Why my computer won't work either on the 3.8 or the 3.1 or is it that they won't work for the other Quote Link to comment Share on other sites More sharing options...
