ScoobyDoo82 Posted March 16, 2011 Report Share Posted March 16, 2011 Well I got my trans mounted up today (its out of a 1990 Lumina, 3.1)... and I was just wondering if the torque converter bolts are different on the 90 than my 89 transmission... I can get them threaded in a little bit but then it becomes really hard to screw it in and I dont want to cross thread them... Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted March 17, 2011 Report Share Posted March 17, 2011 The flexplates appear to crossreference from '89 to '90. They're both 440T4's/4T60's, right? The 125c and 440T4 flexplates appear to have different part numbers. Quote Link to comment Share on other sites More sharing options...
ScoobyDoo82 Posted March 17, 2011 Author Report Share Posted March 17, 2011 Yeah both were 440t4s... I just chased the threads today and it solved the problem. Quote Link to comment Share on other sites More sharing options...
