ScoobyDoo82 Posted March 16, 2011 Report 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
digitaloutsider Posted March 17, 2011 Report 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
ScoobyDoo82 Posted March 17, 2011 Author Report Posted March 17, 2011 Yeah both were 440t4s... I just chased the threads today and it solved the problem. Quote
