How to check fluid level after an 8 speed tranny service

[Wild one]

I'm getting tired of posting this on every 8 speed thread. Post 29 by Stuart has the proper procedure for doing the fluid level check after you drop the tranny pan /filter and replace them with a new pan/filter assembly.

Am i missing something? That did not tell me how to check. It just tell me how to achieve the proper level

What if i haven't serviced the tranny and i want to know my level?

Same procedure,start out cold and run it through the gears as stated ,with the rear tires lifted high enough to level the tranny pan rail and pull the fill plug to check if fluid dribbles out or not.Why would checking it be any different???

Thanks GI,much appreciated.

You actually have to lift the front a bunch to level the rails, especially with factory rake. Ultimately ending up with more fluid than necessary since the fill is on the rear side. Most consumers won’t notice a difference in an extra half/liter if using the overpriced green EPA water.

Nope you jack the rear tires up to level the pan rail Tim,lifting the front tires puts the pan rail on a down hill run.Plus you need the rear tires in the air for it to shift into 2nd gear and to hold it at 2,000 rpm with the rear tires turning. With-out the pan rail level you'll never get the same amount of fluid back in that you've drained out and you won't get a proper reading at the fill plug.Throw a level on the transmiissions pan rails when you have the pan off and jack the rear up till it's reading level front to rear and side to side before putting the new pan/filter back up in place.You're not leveling the trucks frame rails,you're leveling the actual transmission pan rail that the pan bolts to.Park your truck on a level piece of ground and then lean under and look at the tranny,it still points downhill to the rear even with the front rake the trucks have

Your trans must have a different output angle then!

I would go by ZF’s procedure vs wherever that came from.

Those are the instructions that come with a "brand new" ZF tranny,only cost me several thousand to get them,lol. Not a rebuilt tranny a brand new tranny right from ZF. You better look closer at your tranny it points downhill to the rear of the truck,if yours points different you have the only truck built with a tranny pointing uphill towards the rear. That truck of yours must eat U-joints pretty damn quick,as an uphill facing tranny is going to put your U-joints in one hell'va bind lad. Before you start arguing a ******** point,get out and actually look at your truck close,and think about what you're saying,and think about what would happen to the driveshaft if the transmission did actually point uphill. I'd also like you to find any North American built truck that actually has the rear of the tranny higher then the front,get a pic of this odd ball truck when you find it,otherwise i'm not going to believe you,lol

After reading those instructions for a second time today,did you see where they say to fill the transmission according to fill instructions,but nowhere do they give you the fill procedure,you either didn't read it close,or you're just in a bad mood this morning and want to argue dumb points. 3rd paragraph down read it close Tim,and quit arguing ,as they don't give you the fill procedure,all they say is fill it according to fill instructions,which are the instructions that came with my new tranny and which are posted on here.

No argument just contradiction, in all reality most should use logic and replace exactly how much left on the “sealed system“ in my case, was just under 5 liters.

Which removes any doubt on a PM when the transmission system was working great prior


I don’t drive the truck with the tires in the air and ZF doesn’t manufacture and fill/test these 8s differently based on the application. Do you think they’re going on vehicles dry In mass production like the Ram?

This should be a sticky then everyone can find it.

If you only had 5 litres drain out your either doing something different or your tranny is different from most,as the majority of guys are draining at least 6 and upwards of 7 litres when they do an 8 speed service.If I was you,i'd jack the rear of the truck up,do the procedure the way the instructions say to do the procedure and re-check the level. But it's your truck do it the way you want,but if it was me,i'd re-check the level properly,just my 02 though.

I planned to add another gallon of blue cap amsoil soon to get rid of more of original fluid so we’ll see what it takes.

Amsoil immediately got rid of the initial cold rough 1-2 shift so probably not low and cooling better than it ever has since custom tuned.

10 Liters total right? probably not going to miss 1 unless seriously abused.

Found this thread and got to reading, double checked to make sure it wasn’t posted on April 1st.

Still have the trusty ole dipstick on my Cummins.

What team of geniuses decided a dipstick wasn’t good enough? Let alone that a pan/filter combo was a bright ideal?

Whoever it was needs to have their sack get caught in a Roto Rooter before they can reproduce and we end up elbow deep in idjits.

I’ve heard some high end luxury cars have done away with dipsticks as the original owner will never pop the hood let alone pull a dipstick but come on, its a pickup truck.
