Do THIS for better transmission fluid level in your 4L80e

Sensationalized for extra emphasis.

[@lelenbates3367]

I am changing my filter so I am going to check this. My truck spends most of it's time in the mountains of Idaho so it is rarely level when driving and there are some steep accents and descents. Thanks for the video.

I think this is also a good illustration of how important being in a very level surface when checking the level with trans installed in the vehicle.

❤ thankyou for the clarity and quality of an explanation on this!!! Forreals appreciated!

[@voidisyinyangvoidisyinyang885]

Wow! I was a quart over and my transmission seems to run a bit better - and I was freaking out. This vid really confirms to me that being a quart over the max line is ok!!! Thanks so much - I have the 4l60e deep pan. I read forums where only one person said they went a quart over. Everyone else said only a half quart max over. So I was scared about damaging the transmission but like I said - it is shifting better. So I'm leaving it now for sure. thanks

Caveat here. A quart over in YOUR SITUATION. Obviously if someone checked their dipstick to the pan rail which you obviously didn't do, they'd find the proper fill level. You just found out your dipstick doesn't match

[@voidisyinyangvoidisyinyang885]

@@lollipop84858 I can't remember now - I installed an external OEM Magnefine magnetic filter - I had to customize the connection. The transmission works way better now. I haven't changed out the filter yet but I did a dipstick change out of the trans fluid. So I haven't checked it since I did that maintenance - I need to check my records. thanks

I dispute the 1/4" = a quart, since the entirety of the valve body would be 'under water' and taking up volume needed to raise the level in the pan??

[@TurboSleeper]

The valve body and filter are displacing fluid volume. I'm aware. Just let me be over the top dramatic so I can really hammer home how important this is.

[@danielkingery2894]

@@TurboSleeper so then....you admit that the 1/4" in the empty pan is an exaggeration of the amount needed to fill the SAME pan to the SAME level with all the other crap in there?? So what's the point in lying about the level vs. volume?

[@voidisyinyangvoidisyinyang885]

@@danielkingery2894 his point is the displacement of fluid does not occur as much if you're doing WOT with inertia or from a steep angle, etc.

this is very helpful

[@jacobtravis2847]

My hot fill line on my 95 4l80e in a winnebego motorhome seems to be spot on with the top of the valve body.

[@lollipop84858]

Liar

[@GrowingPains917]

Pretty sure “above” and “below” were mixed up a few times since the transmission was upside down.

[@jeffandtex]

Would the 1/4" above the pan rail be the absolute full mark? or should I make that point the mid between low and full on my dipstick? Thanks

[@hongmihnhahn7081]

Level 1/8 above the pan rail is the best when hot?

[@flinch622]

Sounds about right. Cold height would be near the pan rail, which is acceptable [running]. I notched my dipstick about 1/16" above the pan rail to serve as my cold level reference - so far so good.

[@bobhunt595]

Can you be a little over filled or is that detrimental too?

[@timhoover891]

I am the dipstick

[@Jean_1999]

Goes to show filling up a 4L80E with Fluid is not bad of you fill a little more oil than recommended. I always say little bit more oil never hurts old engines and Transmissions

[@todddann3134]

Did you measure to the bottom of the meniscus?

[@lollipop84858]

Obviously he didn't. You can clearly see he didn't.

It's not rocket science. Stick to knitting. Care mustn't be for you.
