I looked it up on rockauto . I got the one for my Olds from Kem parts and the car runs and shifts great. I'm sure I need motor/transmission mounts Lots of movement from the 2.3 . Rockauto says "PRE ADJ AL4D TRANS 4-140 2.3L SOHC " . Guess that means adjustable . It's for the 2.3t C3/C5 . There is one listed under AL4D as well and says likewise . The AL4D is a C3 is it not ?
