They probably did it a similar way I would have done it.
Doubthathey used any temperature measuring device.
Probably just opened the drain and refilled to the overflow tube.
As a registered tree-hugger and Greenie, I walked home three miles and was home 30 minutes when they called to come back.
With todays technology and everyone having cameras in there cars and or cell phones it is not very likely that they would have charged for work not done, especially with you being able to sneak and check up on themâŠ
I used to tell customers that you are more then welcome to watch from a safe distance any and all work being performedâŠ
But if I didnât trust the shop doing the work I dang sure wouldnât have let them work on it at least without keeping an eye on itâŠ
They probably used a proper tool and adapters to fill the fluid
They probably used the correct fluid
And they probably used a professional-level scanner to make sure everything was being done at the correct temperature
Again, I 100% disagree with your assumption that the shop did it the same way you would have

When my radiator needed to be replaced, I was concerned that the trans cooler might have caused the fluid to be low. I just stopped by the transmission shop and they put it up on the hoist to check it. No charge.
Since I hadriven the cold emergencyehicle only 3 miles, would the transmission have achieved adequatemperature?
I would have used the Toyota âWorld Standardâ transmission fluid.
Would have had to buy a little pump which attaches right to the quart bottles to pump it above the filler/overflow tube.
After driving somewhere, would have opened the drain plug assuming there would be some overflow into the tube.
There was when the drain plug was first opened after Lexus had filled it.
Checking my IQ. Yep, I quit.
From Airplane engine to RGâs transmission nonsense with the annoying childish spelling just proves RG is a Troll who just wants to argue and be noticed.

Iâve seen this problem even among a subset of Silicon Valley tech engineers and scientists. Grow up in a family that has privileged status, then university/graduate school. Great skill at memorizing textbooks. Never had to use a screwdriver. These folk usually divert their careers toward computer programming, or financial analysis, less of chance theyâll come face to face with a screwdriver ⊠lol ⊠usually these folks are very successful in their career, just not at fixing their lawnmower. They hire gardeners instead.

Depending on ambient temperature, it could have taken 30 to 60 minutes for the transmission to cool to fluid adjustment temperature. The fluid level is adjusted while the fluid temperature is between 95 F and 113 F.
At operating temperature, the fluid level will be 1/2" to 1 1/2" above the overflow tube, you should not drain that fluid from the transmission.

@George_San_Jose1 I have noticed a real difference between the younger faculty and the faculty in my age bracket. I grew up doing the maintenance and minor repairs on my vehicles. I overhauled the 2 stroke engine on the LawnBoy mower. In fact, the ownerâs manual that came with the mower my dad purchased in 1955 had illustrations on how to disassemble the engine. You donât find that in the ownerâs manual in todayâs lawnmowers. We had Heathkits back on those days where we could build our own electronic devices. When I wanted a high fidelity system, I first bought just a record changer. I figured every radio had an amplifier section and a speaker, so I found a circuit diagram for my clock radio and installed an input jack and a switch and had a radio/phonograph combination. Later, I bought a used amplifier and a 12" speaker and made an enclosure for the speaker out of celotex from plans in a now defunct magazine Popular Electronics. I bought a used portable black and white television for $25 that I kept operational for years. One of my colleagues bought and assembled a Heathkit color television.
Todayâs flat screen TV sets just have an entire circuit board replaced if the set is even repaired.
The younger generation doesnât have the learning experiences I had with the vacuum tube electronics, and automobiles that were easier to service.
To me, some things are backward. I did computer programming. I told the computer what to do. Thirty two years ago, I had a Ford Aerostar minivan that was running rough. It was under warranty, so I took it to the dealer. In the middle of the morning, I got a call from the service manager. He said, âThere is something wrong with the engine on your Aerostar. However, we canât fix it because the computer canât tell us whatâs wrongâ. I figured it was missing on one cylinder and suggested that the technician pull each spark plug wire with the engine running and then reattach the wire and do that for each cylinder until pulling a plug wire wouldnât make a difference. âCanât do thatâ, the service manager replied. âWe can only do what the computer tells us to doâ. I then said I would pay an hourâs labor if the technician would pull spark plug wires as I suggested. If that located the problem, the dealer would fix it free on warranty. If it didnât locate the problem, I would pay the labor charge. Twenty minutes later, the service manager called back and said my Aerostar was fixed and there was no charge. When I picked the van up, the service manager showed me the bad spark plug. Part of the ceramic tip around the center electrode had broken off. I told the manager I would probably be back with the same problem. He didnât think so. I was back. One cylinder head had a hairline crack and when the coolant leaked into the cylinder, it eventually cracked the tip around the center electrode of the spark plug. The entire engine was replaced under warranty since the cylinder wall was scored. Now this was 32 years ago. The Aerostar didnât have a check engine light and the diagnostic equipment was not as sophisticated as todayâs equipment.
My point is that I donât want to depend on computers to tell me what to do. I have Mrs. Triedaq for that. I am sure the computerized analysers are a real aid in diagnosing engine problems. However, I think the understanding of how something functions needs to be there as well.
By the same token, I think young children need to be taught the addition and multiplication tables and do arithmetic with paper and pencil before they are allowed to use calculators. This gives them a feeling for numbers.
I know I havenât kept up with the times. I donât have a scanner to diagnose my car problems. I donât attempt to repair my flat screen television. It just seems to me that the younger generation is missing out on the experiences I had.

Iâm confused. Youâre this self-proclaimed master mechanic who knows more about vehicles then the engineers who designed it. Why would you take a vehicle to WalMart for a simple oil change on very simple vehicle?
2 Likes
Never such a proclamation.
They accomplished the $8 oil change while we.re shopping in the store. I bought oil and filter in the Walmart and brought it outo them.
Later started my OCD overnight-drain oil changes.
Thank you. No way to measure it.
How do they "adjust " (know) the fluidevel?
By removing the drain plug and allowing the excess above the overflow tube to drain out.
Exactly as I would have done it.
Or musthe temperature be within the 95 to 113F. range to drain it?
An old car can have two scales on the dipstick, one for cold, one for hot.
With a modern transmission there is one desired level, observed at a narrow temperature range. That level is at the top of the overflow tube.

Of course it must, thatâs why Toyota/Lexus specifies the temperature range. DUH! 
Yes you have.
