hello a couple weeks back i reistalled my tci 3500 stall converter back into my car and i lost one of the bolts and ive been driving it with just 2 bolts and im starting to get a slight vibration does anybody know what size bolts this converter takes i would greatly appreciate it thanks.
First, I wouldn't drive the car with only 2 bolts installed. For the exact bolt size try contacting user Kevin Winstead. He works for TCI and is very helpful. Or you can remove one of the bolts, take it to a hardware store to match the thread and length.
