What's the speedo cable that goes to the trans to the engine bay I keep getting the 1 to the speedmeter to engine bay the trans is a 30 spline 700r4 my broke in the trans and its leaking a little

 

IIRC, there are two two-part cables, an early one which went to the transducer, then the speedo, and one probably like your 87, which is simply two parts (Why? Who knows). Finally, there's a one-piece, which seems like the best choice. Sorry, no part numbers.

When I looked up PN for a few different GM vehicles years ago, I found the two-piece non-transducer application cables tended to be installed on cars with higher (3.73, 3.42) gear ratios. But the lower geared models (2.14, 2.29, 2.41, 2.56, 2.73) tended to be listed as using the single-piece cables.

I've also had poor results from swapping a new GM one-piece cable into a car that originally had a two-piece cable and 3.73 gears. I pulled that later and installed a used two-piece cable with over 150k miles with better speedometer stability.

Sometimes it's easier for drivelines to be done as 2-piece from a manufacturer perspective and that may apply to speedometer cables as well.

In an indirect manner, I found Napa's cable listed for your car is indicated to be two-piece. Hope it works out for you.

 

My car came with cruise control I will try to take pics of what I'm taing about

 

Is the car not an '87?

If a cable goes into a transducer (located on the driver's side more or less under the wiper fluid tank) and another exits, I'd be surprised as, IIRC, that configuration ended early on--my 85, at least, isn't so equipped.

This is it under hood

 

Looks like an OEM 2-piece cable to me.
Try Napa.
