Okay what should be super easy is killing me. Yesterday I changed the t fluid and forgot to refill when it was running. It would not go into gear and was throwing code 732 which I thought was because it did not have enough fluid. Today I start the truck up and remove the fill cap and about 2 quarts of t fluid pour out onto the ground. I put the fill cap back in and it still does not want to move and the M, S, and D are all flashing. What am I doing wrong?

 

The fill plug has to be removed while the engine is running otherwise you will loose lots of fluid. You always check with engine running always always always. Park it on a incline and get as much in as you can and limp it to a tranny shop.

 

You need to read how to do things before you burn up your tranny.
Go get a shop manual and in the mean time quit driving it.

 

Park it on a slope as the good member has said to do.
Start it up.

Put in as much as you can.

You may or may not get moving again.
Your transmission computer has detected a fault.

May be a hard fault in the gears.
Or a soft fault.
Soft fault may be that the transmission ECU commanded a solenoid to close or actuate and it did not.
The solenoids control the shift points adn when they actuate, pressure is diverted to where it need to go to lock a clutch which holds the planetary gears for the desired ratio to match your terrain and speed.

A soft fault will clear.
Key off - engine off.
Then restart the engine.

You need to have enough fluid in for the transmission pump to suck it in to the transmission pump intake via the filter
and pressurize the rest of the transmission and the torque convertor.

 

When the advice is to park on an incline, you guys mean that it should be parked with the front high and the rear low?

 

Yes. Jack the front of the truck up in the air as if your lifting it up to God. Then pray you didn't fry your tranny. Good luck

 

Dont use the bottle cap without jack stands please

 

And make sure you set the parking bake and chock the rear wheels.

 

Okay guys thanks. I still do not understand why when I warmed the engine up today and removed the fill cap why so much fluid came out. I ran it through the gears twice and did not drive it. Its just got me a bit confused. Figure I filled the pan yesterday then when I went to top it off today it shot it out.

 

Specifically - you warmed up the engine.
Then turned it off. (turned off the engine)
And, then took out the fill plug...

Engine must be running and in "N" I think or "P".
I did mine on a flat surface in "N" with the E brake on.

With the engine off, the transmission pump is off.
All the fluid returns to the transmission sump.

Engine on - transmission pump keeps the torque convertor filled and
creates a little vacuum there - keeping the fluid displaced and more room in the sump for you to add fluid until the fluid comes out the lower threads of the drain plug..

This is the same as checking a Dicovery I. Discovery I is checked with the engine running - as are most cars.

You just have no dip stick to aid you.
You are stuck crawling under the rover on the D2.
Pretty stupid if you ask me.
