Not having a transmission dipstick Is not good.

Talk about a pain, 2016 Ram 1500, transmission fluid change is a 10 star PITA. Have to raise the rear, rear tires about 10'' off ground to level the tranny, plastic tranny pan has to be removed, filter is built into it, so you need to buy a new one, I purchase a new metal pan with a drain plug and can now replace filter in future. When placing new fluid, tranny must be at certain temp. range and you have so much time to place, it must start running out of fill hole. Then you need to run truck thru the gears. I rechecked the next morning while truck was on stands. Kinda of scary, jack stands and wood blocks I used. Dealer said fluid was life time (refused to change fluid) but maker of the tranny said no, emailed them, fluid should be changed at about 40,000 I think, 30,000 miles if towing,,, Zurich? maker of tranny if I remember. Fluid and filter was changed at about 100,000 miles, pitch black the fluid was, could feel the difference once on the road, smooth shifting, still nice after about a year, and I used valvoline max. Yes, it was a mess.
 
You have a transmission that is LEAKING-some where. It's not normal. A normal transmission DOES NOT LEAK.

Thank you for your very informative post, Captain Obvious. Is there any way you can make your post any more bolder? :rolleyes:
 
Dipstick is nice, no doubt. But the automatic I had with a dipstick seemed hard to read after adding oil, reading it was hard as the tube had multiple bends. So I like the fill port with a length of pvc tubing.

But the old school manual trans drain and fill plugs were the best… I get it, automatics can’t do that for various reasons, but they sure defined the simplest way.
 
I have been doing my daughters Edge. You can fill from the top vent. But you have to remove a plug on side of trans. Then heat fluid to about 195 degrees F. When it is heated to proper temp, and finished draining cap it.


I have 2 6R80 Ford vehicles that I use a funnel and hose, with curved metal tube going into the trans. It is on the slow side. I had an accident doing it on my F150. I had a piece of silicone tubing connecting the PCV tube to the funnel. I wrapped electrical tape around that area. When I was almost done with the job it popped off. Big mess with about a half qt trans fluid.

I am going to make a better set up for that job. Really fun on the F150, and Expedition with a catalytic converter right next to the trans. They require the fluid to be scalding hot to finalize fluid level. Of course with the engine running..... Nothing more fun than 200 degree fluid, and several hundred degree converter right next to my hand.

B&M is gouging for the dip sticks for sure.
I need to get the funnel set up perfected with a valve inline.
My 6R80 dipstick has hashed A and B marked areas on the dipstick for checking the fluid hot or cold so it doesn't need to be 200f, basically just running so all the fluid can be filled. I've drained and filled a number of times and always fill to the lower level with cold fluid which seems to work perfectly.

What's next...no steering wheel?
I think they're working on it.

An idea:
Let's measure and diagram locations where holes can be drilled to accommodate dipstick tubes (and thus, dipsticks)?
Someone did this for Haldex bevel gear units on a Volvo board.
A drain and a fill hole.

To jjfw post#22:
I scoped out that job for a friend's 2017 Jeep Grand Cherokee 8-speed.
Dealership pan and juice were ~$325. and my pal chickened out.
$820 it cost him at a garage.

My concern with the metal pan with the replaceable filter was acquiring said filters in the future.
At the time, the meatal pan was listed on RA but the replacement filters were not.

I agree with OP and restate my argument that it doesn't do any favors for used car shopping-- gone are the days of pulling the dipstick to get a general feel for color and smell.

I will say since I got my Mityvac pressure filler (which is essentially a glorified garden sprayer) I curse these a lot less. I actually like that you just pump it up by hand because I hate fighting with hoses or cords, and it does NOT take that much pumping to get an acceptable pressure to transfer fluid. It comes with a few angles to drop in the fill hole but I've rigged up a full 180 for Ford 10R80s, although I was still using a hand pump here, almost exactly a year ago:

The 4L30E was the first dipstick-less transmission I ever did a fluid drain/fill on. They are an oddball how the 4th gear is added on to the case in it's own housing and has it's own small pan that you can't drain w/out removing it.
 
Most all manufacturers are doing that with Transmissions now some are even doing it with engine oil. They all claim that it's a portal for contamination. So they seal the Transmissions and say it's lifetime oil! What they really should be saying is it's guaranteed oil for your warranty. At least they allow us to change our engine oil.
Now before I even buy a car one of my prerequisites are what type of maintenance is required and how easy is it.
I downsized and went with a little 2.5 sewing machine Toyota RAV4 because of the Simplicity all the way around,, piece of cake working on it.

If I had the money I'd be driving a 4x4 lifted Cummins twin turbo!
 
10R80 owner here. The dipstick from a 6R80 will fit and might be moderately useful. Of course, the 2.5” dipstick fits underneath the fill plug, which is hollow and maybe 1.5” long internally, so you’re still going beneath the truck to break loose the 19mm fill plug right next to a cat (I hear you @BrendanC) and then try to manipulate these lego-sized plugs and dipstick with your best attempt at pretending you have tiny fingers.

I also use the funnel and hose from above method. Simple, cheap … but can take some time to pull down 6 quarts.

After doing this a few times, I’ve really come to appreciate Toyota’s method more and more.

I only did it on the Tundra. I think Camry, their 6AT, I think there was a widget that could be used in the trans pan and set to the right height for oil temps that were not in the super small window. I was not crazy about the small temperature window but it was sorta easy. And on that transmission I didn't worry too much, as it wasn't known for failures--this was something that really only needed doing every 50k.
 
You have a transmission that is LEAKING-some where. It's not normal. A normal transmission DOES NOT LEAK. It's a sealed system. The fluid doesn't evaporate. It's has no where to go-assuming it's not leaking. A dipstick is not needed.


Somebody forgot to take their meds again …CKN ..

Ya need refills ? :LOL:
 
No dipstick on the 8L90E so I added one to my 2018 Sierra 1500. There is no reason these new transmissions shouldn't have a dipstick to check the fluid.
