Iv just done a test on the wirering loom no problems continuity between pin71band pn 10 transmission plug
But did do a test on pin 10 on the transmission itself and the body of the gearbox and it belled back as continuity
Does this mean the transmission needs to come out again or is the speed sensor grounded anyway
Either way it needs to be done any help from anyone would be greatly appreciated

Checked pin 10 from transmission itself and i have continuity from pin 10 transmission to ground body casing of the transmission does any one have a zf8hp70 transmission to check pin 10 to see if it has continuity to the transmission case this would really narrow down my fault thanks anybody
