transmission pan edge wet; drain & fill
Time for another transmission fluid drain & fill.
Surprised to see the edge of the transmission pan wet. Wonder if anyone had similar experience?
Maybe it's time to replace transmission pan gasket?
Drain & fill was carried out smoothly. drained 2.8QT (environment temp 20C), filled in 3QT, then performed the fluid level adjustment using the official jumper wire method.
It took 9 minutes of idling for the transmission fluid temperature to reach 35C.

I would change that gasket everytime the pan's removed. Did you change it with the last drain n fill? Fresh looking fluid on the bolt heads.

After that I did two drain & fills in 2017, and two drain & fill in 2018. Therefore the old fluid was almost all gone.
will replace the pan gasket soon.

You did a good job with the fluid changes then, even tho it's a small amount on the bolt heads it's very clean.
When I did mine I thought the bolts should've been tighter...they were set to around 70 in lbs so I will have to keep an eye on them for leaks.
With the shape of the gasket and the steel inserts I think a person could go a bit tighter just by feel.

It should be replaced every time since it will lose some of its "springy" attributes and may no longer perfectly seal.

I thought about replacing it, but there is a bracket in the way covering two of the pan bolts. That bracket connects the two exhaust pipes. And the bolts are rusty. Will need to get prepared handling these two bolts: get new replacement bolts.

The rear crossmember on the awd model gets in the way of the bolts also, I just used the open end of a wrench on the back 2 pan bolts.

The only time my pan gasket leaked is when I accidentally overfilled it, didn’t realize it, and drove around like that for 15,000 miles...fluid forced it’s way out the sides of the gasket.

The gasket is not re-usable per the manufacture manual. I believe, there is a small tear can be seen in the gasket in your pictures. Which makes wonder about overall state of the seal.
