Re: Transmission part. What is it & where does it go.

This is one of three different versions of what is called a "case saver". This takes the place of the "anti clunk" spring. This should only be used when the aluminum case lugs are very worn.

If you have a 1988 or later V8 700R4, it will have the .282" intermediate/reverse boost valve. If you have under 400 FWHP, this valve with work fine. This valve gives firmer 1-2 manual shifts.
