Last time I changed hydraulic oil the New Holland brand was already dyed red in bucket. No sight glass but makes it easier to see on dipstickHad a BMW Z4 that would check the oil and show the level on a scale in the dash cluster.
Lots of newer motorcycles going to a sight glass. My Kubota has a sight glass for hydraulic oil and a dipstick for the engine oil. I had to put a dye in the hydraulic oil to see it reliably.
just started reading this thread but...View attachment 5473167View attachment 5473168What is it with no dipsticks these days? Do they not trust people to look at them? I changed the transmission fluid in my daughter’s car and there is a fill plug on top that access to is tough. It’s a 2016 Ford Fusion, 150,000 miles. Then there is a plug on the side you remove and fill it until it runs out. Then drive it to warm it up and remove the plug and check it again. A dipstick would be much easier.
at least you have it figured out. I'd be skeptical of a Quik Lube place to change the fluid on that modelThe fill plug on the Fusion transmission is on top but the access is terrible, buried under the air intake hose, wiring and an AC hard line almost on top of it. It took a couple of minutes to get it out but 10 minutes to get it back in.
What about checking to ensure you haven't cooked it? One thing that they finally started adding is a transmission temperature gauge. Aside from being able to monitor, it made me realize how important a cooler is. My Colorado with cooler runs about 95 pulling a 3000 lb trailer. The GMs my company bought didn't have coolers, and ran around 190° in everyday driving. They also overheated quicker when working them, on more than one occasion I had to stop to let the fluid cool when pushing through snow.I think we've reached the point where automatic transmissions are no more likely to leak than manuals. When was the last time you saw a dipstick on a manual transmission?
Newer? My 1976 Kawasaki KZ900 used a sight glass. No dipstick. I don't know that they were the first but all the 900's and KZ1000's used a sight glass. The Z1 was the first of the 900's. Sight glass is right above the brake pedal on this Z1b.Had a BMW Z4 that would check the oil and show the level on a scale in the dash cluster.

I'm thinking a 2000 Pontiac Grand Am I had was without a dipstick. My memory might be faulty or even corrupted.Surprised there is a drain and level plug accessible for changing oil. I don’t remember which vehicle it was but it was a “sealed” trans with no fill port either.
My Colorado is fine. It's all of the other trucks i've driven.given all the sensors these days, wouldn't a dashboard check light trip if tranny runs too hot on current models? what year is your Colorado?
