I am changing out the transmission filter in my 2000 H&H/HSE. How many quarts of fluid should I buy? The Rave I have does not give a filter change-out volume in the repair section.

Also- I know after static fill you need to go through the gears and the put it back in Park and keep it running to pull more in the tranny as you do a final fill- and that you have to do it fast since it is a cold level at the fill port.

Does anyone keep it in neutral while the motor is running and you are under the truck filling? I heard the pump is still turning in neutral and not in Park.

There's a section earlier in the manual called "Lubricants, Fluids and Capacities". I agree it would be helpful if it listed the capacities along with the repair instructions :P

9.7 litres or 20.5 US pints.

There is a disclaimer at the top that says these are approximate values and to check the procedure for checking the level. For the facelift models I believe this is "fill it until it leaks out of the filler hole".

Level ground, engine running, fill it up, run through the gears, fill some etc until full.

Are you saying that when you change the filter you can put all 9.7 liters back into the transmission? I normally find with an automatic I can only put about 1/3 of the total because most of the fluid stays in the torque converter when you dump what is in the pan.

I just looked at the Atlantic British video and it says that you bring the truck up to operating temperature to check level. I thought it was a cold level check because the fluid expands when it is hot.

Sorry, I misread the question!

When I did mine I got quite a lot out.

I bought a 10L bottle just in case I needed the full amount - it took a lot but not the whole bottle. I'll see if it's still in the shed somewhere and try to estimate how much is left in it.

I did mine cold.

OK-- I went through the Atlantic British process which I knew may be wrong-- but things went strange fast. I got about two and a half quarts in the pan statically. Started up the truck and let heat up a bit then went through the gears and then kept it running. Went under the truck and started pumping in fluid- got about three more quarts in and it started to drip past the tube in the hole and I thought fine-- soon as I pulled the tube out to check how quick it was really dripping without the tube in the hole-- it pucked out two quarts of fluid. I am letting the truck cool down and will start over.

I think I proved that AB method of doing it warm is the wrong way to go-- all of the fluid in the tranny must have heated up - expanded- then blew out of the fill hole. Great that a supplier would make video which is wrong.

Now I have to go out and buy more fluid since it went back into my drain pan which was empty but still had dirt bits in it. I did pour it back into my empty bottles using a fine mesh paint strainer- but not worth taking a chance.

I measured the amount of fluid I dropped out when I first pulled the pan--about four quarts.

If I remember correctly when I changed my fluid it took around 9pts to fill back up.

To some degree it would depend how much was in there to start with, you won't get it all out of the torque convertor, but when I've had to do anything which involved changing the fluid, I would reckon to have at least the full capacity available as your guaranteed to lose some somewhere along the process.

Your best bet is probabbly to refill it as best you can to the right level, drive it around a bit to let it get all the system filled up again, then recheck it as per the described method.

It would be much easier if it had the dipstick like the GEMS ones do.

Rob- that makes sense to me. It amazed me that it puked back out almost 2 quarts even though it was warm/hot. My fear is that there is something else going one- going to wait till cold and start over.

I assume that if I had removed the fill plug before I pulled the drain plug during the filter change-out that I would have drained off at least a quart or so of fluid before it stopped dripping due to the pump is not pulling fluid into the torque converter.

I always seem to have manual boxes so this auto box stuff is a bit foreign to me.
