Asking DIY mechanics or pro mechanics

Looking for a vehicle scanner that shows transmission temp 🌡️.

Gonna do a drain/fill on my wife’s ’24 RAV4 transmission, need it at _97‑118°F for a proper fluid check.

Anyone got recs that aren’t pricey? 💸

I’m a DIY maintenance dude, not after a crazy expensive scanner.

I'm a professional mechanic. I recommend the Topdon Bluetooth dongle. I have the OBDLink dongle; it works okay in a pinch for basic data, but it can be finicky with some apps.
