I had another post but I have since learned more accurate detail (like which trans I have lol!)

I just picked up this truck.



1990 F350, crew long box, 4x4, 460/E4OD

On my way home with the truck I lost 4th gear.

I was not towing anything, running unloaded on flat land with the cruise set at 60mph. All the sudden I had a growl from what seemed like the front of the truck, the things that flashed through my mind where axle related. I touched the brakes to cancel the cruise. The sound lasted for a few seconds then it was gone, I pulled over along the road to look things over, nothing was leaking, nothing appeared broken so I got back in and took off. But I never got 4th gear again. It will attempt 4th but it seems there's nothing there. I get a little spike in rpm, like a quick slip of the drive force and a 150-200 rpm spike on the tach then back down and it's still in 3rd gear.

4.10 gears, I'm running about 2650 rpm at 55.

I had been running maybe 2300-ish at 60 mph before I lost overdrive.

When I let off the gas at cruise speed the driveline does spin the engine, I seem to be locked up in the torque converter.

That's really all I know right now. No flashing light on the OD cancel button.

Looks like a rebuild runs around $1250, is this my best bet or is there something I can check for inside the magic gear changing device known as "auto transmission"?

(can I pull the pan and see anything that I can fix?)

Thanks.

 

lost everything now, junk.

No forward, no reverse, just sick noises.

Sick chunky transmission chunky stew noises.

And now I'm sick...

 

Unfortunately, that red thing out front probably has a lot to do with your tranny troubles. Sorry, dude--been there several times (though not on a just-purchased vehicle), it's never a good feeling.
