Battery condition/connections? Lose ground connection? Any OBD codes?

 

connections seem fine. And battery hasn’t had any issues as far as week starts or having been drained by leaving lights on or anything. OBD codes show 410, 442, and 455. Which if that makes sense to anyone here, feel free to chime in on that too. Gas cap is firmly seated and I haven’t topped off the fuel like they warn against. I’m in NC and am required to do emissions testing so best guess on whether that will pass with those codes?

 

Try a reteach…

• Step on the brake
• Turn the key to the “on” position, but don’t start the car.
• Slowly cycle through the gears, pausing at each position. You should hear the shift motor and clutch actuator moving.
• Slowly cycle back through the gears to Park.
• Take your foot off the brake
• Turn the key off
• I’ve heard that locking and unlocking the doors at this step is necessary , but I’m not convinced. You can try it anyway.
• Wait a few moments.
• Restart the car. The clutch should function again. Some have reported disconnecting the battery for 20 minutes helps.

Is there anything that happens to indicate that the reteach process was done correctly? Is the lock and unlock done from the key fob or the switch inside?

 

You should hear some whirring and clicking as the gearshift motors move.

 

So I don’t hear anything happening. First position for the key is all the way to the detent where if you go any farther, the engine will start, right? When I turn it to that position and start shifting, I don’t hear any clicking underneath. When I move the shifter to a new gear, it will show the appropriate R or N or D (all flashing). But when I start the car, I can actually hear it shifting into those gears, but not when the engine isn’t running.
So maybe gummed up actuator?
or maybe battery is too weak to power the actuator without the alternator’s assistance?

 

No, the car should not be started. If you don’t hear anything, then he reteach probably isn’t working. Can you try pulling the negative battery connection?

 

Will try that later. How long should it be disconnected? And once it’s hooked back up, do the reteach or just see if it’s back to working?

 

…the clutch actuator motor connects the engine to the transmission…
…the gear selector motors do what the name implies…selects the gear to data collected from the gear selector lever…paddle levers and vehicle engine/car speed…
…the gear motors carbon build up and oil vapors gum up the armature/commutator creating a short that the computer recognizes as invalid thus preventing a gear selection and the flashing D as the malfunction message…
…my recommendation is to look at the gear selector motors…done it twice to my bride’s ride clearing it back to normal operating mode…

jetfuel…my take on it..

 

okay will give it a look. Pretty simple process? Any good tutorial or video?

 

I can attest to jetfuel post; one or more sides of the motor assembly can get very dirty with carbon & oil film. cleaning does wonders. The following link will show you how 451 Gear Change Motor Clean | Evilution

… I believe there’s a stickie in the technical section…

okay, I cleaned the actuator and got it put back in the same position it was. Did the reteach and the three bars went away, but now I when I shift into reverse, the reverse lights come on but the speedo says neutral and giving it gas goes nowhere. Same with drive. Unless you guys have any ideas, I might have just immobilized this thing

 

…you mean you cleaned the actuator that seats on top of the engine and has two electrical connectors (black/white)?
…or you did the one under the car??

Jetfuel…???

 

One under the car

 

…this is what a dirty motor looks like…

jetfuel…pretty…isn’t
