#1515547 74 620 flexplate worn down

Posted by Kmralvarado on 07 September 2017 - 07:25 AM

Well let's look back some. The starter was replaced... could it be the problem? Was the old starter the cause of the ring wear, maybe?
 
Is there a thin engine plate between the automatic and the engine block? There should be. The starter should sandwich it against the transmission when bolted up.
 
If the ring gear is worn there is no easy fix, the transmission or the engine will have to come out to get at it. If you have the original engine, any L16 or L18 flex plate will work. If your engine has been replaced with an L20B you will need an L20B specific plate. You can identify the engine you have by looking along the top edge of the block where it meets the head, directly behind the dip stick handle. If you have an L18 you want a 5 bolt wheel, if an L20B you want a 6 bolt.

The L16 and L18 flex plates are the same? I am looking for a 5-bolt L18 flex plate but can't find it anywhere. Would the L16 work fine?
