AT: F4A23 Has no gears

[Edgelessearvin]

So was driving and the transmission acted as if i put it in neutral. Shut off the car and no leaks. Fluid is good, no fuses blown. After sitting for a bit gave it a try and no gears at all. Engine idles up as if it was going to engange. Nothing. I have been on this for a awhile so any help would be greatful

It's very odd for the transmission to fail completely, without any prior symptoms or issue. Did it slip, shutter or whine previously to this? Was there any mechanical noises like axle breaking or something clanking, screeching etc... do you have a scan tool that can retrieve any possible DTCs? To me it's either sounds like a complete lack of pressure, failed torque converter or something mechanical. I would also make sure that the range switch is still connected to cable and is functioning properly, but it's unlikely, that would be an issue, if you have resistance shifting through all gears and key not being stuck in ignition.

Also check all the wiring and connectors. Maybe you a connector vibrated of that's responsible for valve body/ shifting, ground etc....
