I assume you know the procedure to setting the TV cable.

The cable should be slightly pulled out at idle too.
V8 700R4's are identical and bolt up. You need to find the right tail length and similiar year due to speedo gears or signal generator.
700R4's and 4L60's have a poor life span in stock form. Check the tranny. Does it have gears or a signal genator. 92 models should have mostly 4L60 trannys.
