4r44e trouble shooting

[October_V]

Finally have to ask for help.

I have a '99 Ranger, 3.0L, 4x4. 4r44e problems.
No signs of life from the trans, no noise, no movement, nothing.
I have replaced the valve body gasket, original was blown out.
I have a completely different valve body in it now.
All the solenoids check out ok on the meter and the shift engagement rod is on the manual valve.
The shift lever on the console does move the engagement rod
I can roll the truck as if its in N in all the gears except P.

I believe I read that if the TPS (throttle position sensor?) is bad that can keep a auto trans from working.

I have dropped the pan 3 times now and am loosing my enthusiasm.

Looking for some direction to go next before i pull the trans out and do a complete tear down and rebuild.

thanks

Assuming you have already checked fluid level:

Pull a transmission line from the radiator and see if transmission pumps fluid with engine on. Just do it for a little bit.

No gears work? Even the manual ones with od off?

Fluid level is good to go.
None of the gears work, forward or reverse, 1 or 2.
Back up lights do come on when in R, but thats it.
No sound of anything trying to move trany at all.

I'll pull a line and see if the fluid is moving, thanks for the pointer.

When I first opened the bottom of the trans the fluid was nice and clear, good red color.
No signs of burning or shavings, didn't see anything at all to be worried about.
