High transmission temperature?

The transmission temperature goes highly after the speed of 100 mils.
I have installed a transmission cooler to avoid this issue.

Temperature goes down fast if I reduce speed below 100 mils after installing the transmission cooler.

When speed above 100 mils the RPM goes highly and the temperature of transmission only goes highly.

Hi,

Do you mean 100 miles per hour? If that is the case, how high are the RPM's? For you to drive over that speed in this vehicle will cause it to overheat.

You also mentioned about the RPM's. Is the transmission slipping? That will cause it to overheat and the RPM's to go high.

Let me know.
Joe

Hi,

Okay. Am I correct related to the speeds you drive it? (in excess of 100 MPH)?

Also, have you checked for diagnostic trouble codes? Here is a quick video that shows how it's done:

I realize most people don't own a scanner, but since this is happening, I feel it is a good idea to at least check for transmission related codes.

If the transmission isn't slipping and is shifting properly, it may simply be the result of running at a very high speed.

Good morning,

Do you mean 100 MPH?

I would start by changing the fluid land the filter. If it is overheating, that is no good for the fluid. It will turn color and cause clutch damage inside the transmission.

Are there any codes sent to the TCM?
