transmission temp monitoring

[BlackRustBucket]

Most people put in a cooler for three reasons:

1. To bypass the radiator to eliminate any chance of the "pink milkshake"
2. To reduce transmission temperatures while towing
3. To reduce excess heat and stress caused by a turbo/supercharger

If you are concerned about any one of the three then I would recommend putting on a transmission cooler on. If you still have the stock radiator on there I would also recommend bypassing the radiator completely. Mine's currently in the mail since the temperatures are really warming up here in California. The previous owner fried the original transmission 3 years ago because of the supercharger, so I know it's putting out too much heat.

If you haven't seen it yet this thread has lots of info:

If you put a cooler on, there's really no need to put in a gauge since it will be much cooler in temperature than stock.

All the info is much appreciated, I actually have already installed my cooler to eliminate pink milkshake possibility which is why now i'm wondering if it was the right size, did I get the lines in the right spots (send at top return at bottom cooler ports) ect. I used that thread for my install and I agree everything should be better than stock but it's just a lot on the line if something isn't working right.

Think of it this way. At stock the transmission fluid is "cooled" by passing by coolant that is 120*+ in the radiator. Hardly an efficient way to keep your transmission from getting hot.

Now you've got an external cooler being cooled by air with an ambient temperature of 70*-80* AND a bigger cooling capacity. I'm sure your transmission is doing just fine now.

Of course, there's still value to adding a gauge especially if you do serious crawling (not much air flowing) or towing. It's just not necessary. Have peace of mind that your cooler you installed is way better than how it was stock.

I hear you, I was thinking the same thing about the engine coolant temp (only possible downfall being cold weather and it helping bring the trans temp up to operating temp )
But the only off-road I've seen is parking my utility trailer in my back yard lmao.
