Yay 160 deg thermo.

In your transmission? The temperature a thermostat opens in the water coolant passage isn't necessarily the temperature of the any of the exterior pans.

I will agree with Pete that we should be able to believe the trans pan temp won't be too warm, however how about in traffic where temps on a 4T60 have been known to exceed 200F, surely a magnet stuck to the pan w/o airflow in between it and the pan will pick up this radiant heat.

Engine thermo... certainly won't make pan temps higher.

We had a laugh at the Midwest meet when we talked about this order. If these magnets are so strong won't we be picking up screws and other metal debris off the road? It will be interesting to see.

Bill, John will be putting his on his oil pan instead of the tranny.

I definitely thought about the temperature, and knew the magnets lost effectiveness above 80*C, but I didn't know about high-temp options. But at the same time, I didn't think the pans would get that hot. I guess all 10 of us will be the guinea pigs on this. Not bad for only $10 though.

But it seems like now we can agree that the only issue is the temperature and not whether the magnets are safe to use on our pans. I'm happier to know that they have been used for our applications.

1994se, certain size magnets would probably pick up debris. I'm not sure if ours will, but I have a feeling they'll attract things from at least 6" away.

I'm not saying they won't be effective. Merely playing devils advocate since I honestly haven't read the whole thread and some of the ones you didn't order sounded pretty interesting.

Well you brought up some good questions that hadn't been asked before. I'm surprised this thread went so far without someone wondering. But I found proof that they are used on oil pans which I wouldn't have otherwise.

There are some magnets that probably WOULD do damage if placed on our pans. Even a 3" diameter and 1/8" thick magnet has 315lbs pulling force. While that isn't too big of a magnet, it'* surely way too strong for what we need. A couple 1-inchers will do us just fine.

I'll mention that you should be careful with them around computers, credit cards, etc. They won't have to get too close to mess them up. And I won't be held responsible.

I was just about to mention that. 80*C is a tad cool for our trannies.

Yep, you're right. It will be interesting to see how well they do. If we find a higher temp magnet will be better I'll start an order for those. lol

Actually (not knowing what 80C is)
My 4T65 always runs max of 160 (when it actually reaches that high)
My 4T60 always ran minimum of 180.

The 65 was higher mileage at the time of those readings.
