You know, i really couln't tell you; I have not been under there to check it all out yet.

I know. And I will be getting one as soon as i can upgrade that tranny too.

I would like to respectively say bull...

"I" would like to most accurately know the hotest temperature my tranny fluid ever reached...since it is the temp itself that indicates the life of the fluid. The other parts of the tranny can take the heat...

The life of fluid at 230-240 degrees is far far less than at 200 or so. The life of the clutches, lines, VB, etc etc etc...is not much shorter at the hotter temp nor either is the "lubricating" properties of the fluid significantly reduced (when new).

If you change your tranny fluid every oil change...maybe the pan is for you!

im waiting on my mag-hytec double deep trans pan.
good way to cool things down a bit.
I also plan on strapping an electric fan to the trans cooler, hook it up to a relay and hook that up to the ignition.

I have asked many transmission shops, including shops that build race trannies, where to put the sensor, and every one of them told me the pan.

Wonder if that has anything to do with "their" deep pan having a temp port in it.

I have had it both places...it is kinda lik ea pre turbo and post turbo EGT gauge...


It gets real boring monitoring post...and having no idea what pre is.

You would be amazed how hot and quick that fluid can get with a ton of power and the converter unlocked. You barley notice when you look at aveage "cooled" temps. JMHO.

While all of this is true, it is still best to monitor the fluid as it comes out and heads to the cooler because that will tell you what is going on in your tranny.

Test Mule:, the fluid enters at 100*, and cycles through, does its job, and comes out at 150* and heads to the cooler and that is the norm since day one.

Example 1 (trans probe in the pan) Gauge will read at 100*
Example 2 (trans probe in the line) Gauge will read at 150*

Now, lets say that the TC and clutch pack start to go, we all will agree that it will create heat in the trans and the fluid.

Example 1 (trans probe in the pan) Gauge will read at 100*
Example 2 (trans probe in the line) Gauge will read at 200*

With it in the line and monitoring the highest possible temp, it give you an advanced warning that something is going wrong with the trans.

This is very much like the debate on pre or post turbo. You could ask 10 different people and get 10 different answers. We manufacture these transmissions and have for almost 10 years and our techs here prefer pan temp. If you are having problems other than heat related issues you are going to pretty much feel them before you would see them in the temp gauge. But then again that is just an opinion. Not saying Im right, your wrong. Just our opinion here.

The fluid is sucked up by the pump, out to the coolers, and then when it comes back from the coolers, it goes to the valvebody, where it is sent from the valvebody to the apply pistons, and lubrication passages, where it is then drained back to the sump. The only reason you see the higher temperature on the hot line is because that is where the fluid has been pressurized, and pressurizing the fluid is what causes the heat, that, torque converter fluid coupling, normal friction between moving components, clutch slippage during shifts, and clutch slippage during overtorque conditions. My best bet would be to put it in the pan, because when you have a slipping clutch, the first place to get hot would be the pan oil, then the oil that is always getting hot and cold whenever you stomp the pedal to the floor, or release it, which you wouldn't even notice until it is too late. Correct me if I am wrong on anything here.

Oh, and who here has rebuilt their trans themselves, every clutch, snap ring and bolt, one at a time, I have.
