autobox temp

what do you guys use to test the temp of the autobox when changing the fluid ? i have this very thing Non-Contact IR Infrared Digital Thermometer with Laser | eBay will this do ?

You need to measure through/inside the filler hole so an infra red one may not be ideal due to the sensing range of view it has. A normal thermometer is what you need. Poke it through the hole and don’t force it or let go. The best way to do it is leave the car to cool over night then you know it’s cold. Then leave it on tick over and watch the temp increase when it’s time for the level check (see instructions on ere). That way you can watch what it’s doing as it increases.

I have one of these. Bit eggspensive for what it is but I got mine in the sale. Wide Range Probe Thermometer : Thermometers & Hygrometers : Maplin Electronics

The IR thermometer you linked to is ideal for the Turnip Test.

cheers for that info mate. with owning a couple of reptiles i have a couple of these Digital LCD Thermometer - Reptile / Vivarium | eBay kicking about . i think this would do ?

As Hippo said. But don't follow the Hayes manual and take the car for a 5 mile drive. My auto is at 40°C within 10 minutes from cold leaving the engine to idle. If you take it for a drive it will be to hot.

So the probe is ok to stick in the filler hole as you check temp with the engine running ?
I was thinking of the probe being mashed up in the autobox

I use a thin wire K type thermocouple though the filler hole. There is only the valve block below the filler so not much for it to get mashed up in.
