Excellent, thank you

It's just too much of a swing in the over / under filled direction to get this wrong. Thanks for the clarification. I guess I was a couple quarts low when I started.

I changed my fluid and filter a couple weeks ago. With truck sitting overnight, I took 7 quarts out not counting 1/4 or so quart that spilled and dripped. Ended up putting 7.5 quarts back in. I'm not digging the dipstick location at all. It did allow me to pump out 5 quarts or so before I turned the first bolt, so the one + I have to give it is not getting a face full of transmission fluid.

​​​​​it seems I can't get enough fluid in there, or I'm already overfilled. BUT WHICH IS IT?

With the engine running, I get this as my fluid level. So just add more, right? I can't add more unless the engine is running. The fluid level is already at the top of the fill hole with the engine off.

​​​​​​so that means that whenever a tech cracks that plug open, it will leak out, unless the engine stays running the whole time. Convenient.

I put that Lokar dipstick on and it wasn't over $100. I see it for $77 here. I have had mine on for a few years, don't remember what I paid but I love it!

By the way it was easy to install

Old thread but rather than start another.

had local place replace my pan and LV using my supplies.

8 qts 14 oz they used. So they say.

transmission has been running 8-10* hotter than usual just driving it. Sometimes 15*.

max was 206* which I have never seen.

pulled the plug, like OP without the truck idling.
fluid went all over the place.

im at the shop now so they can recheck it.

they claim to have a special attachment that tells them when fluid is correct height/amount.

Follow the service procedure, if its pouring out when running its way overfilled and will cause a failure of the transmission.

thanks.

I believe the dipstick has two level marks. Cold and Hot. A&B. When I used to do them I would drain the pan, change the filter, reinstall the pan. Then I would pour the old fluid into a measured container to see what was lost and then add new fluid of the same quantity of the old. That would normally bring the dipstick reading into the Cold reading area, engine idling and shifted through all gears slowly once. If not in the cold area I'd add a small amount more. Then I'd take it for an easy test drive to bring the trans fluid up to operating temp and recheck to see if the fluid had climbed into the Hot area. If so, it's good. If not add a small amount more. I used to use a length of syn-flex tubing attached to a funnel so I could feed from the engine compartment. The company I worked for had a 2 post hoist so it did make the job somewhat easier.

If you have the service manual then you have this procedure. A running truck should not have fluid pouring out.

As much as I hate paying the inflated prices of a dealership, this right here is one of the reasons for going there instead of to an independent shop.

agreed. They are only $20/hour more and have always been good to me.
Lesson learned.

Interesting the manual says 206-225 is operating temp
and that is when it should be checked. I know it was 175 when I checked.

my posts and others here say they don’t get to 206+.

so what gives?

The 6r80 is regulated to 195 minimum temperature, the normal temp I see is 203 on the dash. Your saying yours won't go past 175?

sorry about the confusion.

she ran 186-195* according to the digital dash readout.
202* when towing.
now gets to 206 without towing.

just seems weird new fluid and she runs hotter than before.

should ANY fluid come out when you remove the dipstick? It isn’t flowing like a river but probably a few ounces when you first open it.
