Did a 4r70 swap and now car wont crank.

[BK_CAULEY]

I was assuming because of the neutral safety switch but i can push the clutch pedal to the floor and it still wont crank. i jumped the grey/red and light blue/ yellow wires together at the trans connector and still no dice. so now what?

edit: i can jump the solenoid and it will fire right up.

you geting voltage to the solenoid?

 

[BK_CAULEY]

no. the red/ light green wire has none. The grey/red also has no voltage. the solenoid is fine.

edit: npw that ive cleaned it it looks kinda white/pink so unsure of color.

you are looking for a red/light green and a white/pink wire to jump. What trans harness do you have?

also the red/grey and blue/yellow wires dont effect cranking. There is two connectors on the clutch switch. the black one is what engages the relay for starting. Auto cars just jumper this since no clutch switch is used.

I have the factory t5 harness still in the car. im swapping to an auto.

Factory T-5 harness should still have the jumper in it. But the black plug on the clutch switch has to jumpered when using an Auto trans.

Start signal for the solenoid goes from Ignition Switch to trans harness to NDS switch(if auto), just looped if manual. Then to the clutch switch and on to the starter solenoid.
