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...

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.

Yeah both were 440t4s... I just chased the threads today and it solved the problem.
