I changed out the transmission fluid on my 2002 S60. There is a "Hot" level and below that there is a "Cold" level. I filled the transmission to the "Cold" level and went for a drive. The transmission was shifting terribly. When I checked the fluid, the dipstick showed no fluid. So I filled to the "Cold" mark again and the transmission shifted better. Once the car warmed up, I filled to the "Hot" level, which is above the "Cold" mark. The transmission was shifting terribly again. I left the car overnight expecting the transmission fluid to go down to the "Cold" mark after the car cooled down but instead, the transmission fluid went way over the "Hot" mark and goes back to the "Hot" mark when the car warms up. I used a 100ml syringe and fish tank tube from Walmart to siphon the fluid out back to "Cold" mark once the car was warmed and the transmission shifted very well with little bumps when down shifting. I kept playing with the fluid level by adding and replacing fluid a little at a time until I got to a level where the transmission shifted very well with no issues. That lasted until I changed out the radiator and lost some fluid removing the transmission lines. I have not reset the adaptions using VIDA as I still need to figure out how to install VIDA onto my laptop. I bought a cheap Ebay OBDII plug and it came with software for Honda, Toyota, and Volvo. Honda and Toyota were straight forward, but VIDA has about 30 files and the instructions aren't clear. I wonder if I have the wrong dipstick as the "Cold" and "Hot" marks do not line up. On my 2005 Honda Pilot, the fluid level goes down when warm and so did my 2004 Volvo XC90. Can someone tell me if their fluid level goes down when warm and whether their "Cold" mark is above their "Hot" mark?
