Transmission thermostat

[Rickpo]

Hi again to all. Ive been seeing how some ppl are deleting the trans thermostat on their 6L80"s. Any ideas why? What benefits come from this? Seems easy enough to do, just wondering why.

To make it run cooler.

How does deleting the trans thermostat cause it to run cooler? I don't doubt that it could, I just don't understand how that works.

Thermostat by passes cooler till a predetermined temperature. If you delete it fluid will flow to cooler full time.

So, in a way, the thermostat operates a door or whatever you want to call it, till the right temp and then lets flow to the cooler. Interesting. I always understood trans fluid is best when as cool as can be, to a point. I understand that it can be too cool, like not the best operation right after a start up, especially in cold/very cold weather.

Thanks for the info.

Where is the thermostat located at? I've never seen it on my suv.

This is what mine looks like. Its on the driver's side of the tranny.

My concern with these is that the thermostat fails closed.

Oh yea, good call. Hell, I would worry of that too. I know my 2002 does not have that but that would be worrisome for sure.
