Need help with stuck tranny

[6shootr]

Well got the death wheel out and cut enough to get the top off.

Everything top and bottom is pretty gummed up. The gears in the lower half move but the components that slide, don't.

Same with the top cover. Everything is pretty gummed up.

Everything looks complete and nothing looks broken or loose.

What is the best way to get these internal components clean and free? I've heard people talk of kerosene or diesel fuel.

We all know the correct way is to remove the trans and tear down and rebuild....however...

Pull the drain plug from the trans and let whatever goop is on the trans to seep out. Replace the plug,

Pour some diesel into the trans enough to cover the bottom gears, no higher.

Jack up the rear wheels and spin the tail shaft with the trans in neutral to circulate the diesel....let it soak for a few hours

Drain the diesel out and let it drip out overnight. Add some light engine oil again just enough to cover the lower gears and turn the tail shaft to circulate.

Drain and refill with gear oil to the full level plug.

You should be able to move the gear sliders back and forth now.

While you are at it, check the clutch plate is free of the flywheel and pressure plate surfaces...if its stuck, do yourself a huge favor and pukk the trans and fix is correctly.
