Transmission Pan Shiny

[cram42]

I’ve seen on the forums, of people having oil residue on the pan.

I went to the Toyota dealer first and they replaced the gasket, pan and trans fluid the first time.

fast forward 4 months, the issue happened again and the pan is shiny.

does Toyota have a fix for this?

so far I’ve heard trans breather, trans cooler lines among the gasket etc.

I do now have a tune on the car, so I don’t want them replacing my entire trans and have to relock my ecu for some BS reason that they got lazy and couldn’t fix.

The bmw and Toyota tech drove the car and said it shifted fine…

This isn't trans fluid. Trans fluid is bright red. This looks like body cavity oil for corrosion protection, which is found in abundance throughout the Supra. I once took a subframe bolt out and a few ounces of yellow-ish cavity oil poured out of the bolt hole.

No other supras do not have this issue.

we know it’s not trans fluid. It’s oil.

but it’s been narrowed down to the trans breather we believe but not 100%.

Confused by this post. trans fluid is oil. If it's from the trans breather, it's trans fluid.

I bet the dealer didn't fill it correctly. Probably over filled it because they couldn't be bothered (or didn't know) the actual filling technique.
