We’ve been checking our trans fluid all wrong..

[Unholy707]

It’s just dawned on me. So I installed brand new cooler lines with thermostatic bypass valve, pulled the cooler/supercharger heat exhanger to clean it out of atf when I did the transmission. When I did the fill procedure, I did it between the recommended temps. At the track, hot lapping the car and due to the g forces, the car has been having 1-2 and 2-3 shift issues, bad enough where the 2-3 shift just didn’t even happen the one pass. If your system is dry and you do the refill procedure per the factory’s temps, the thermostatic bypass valve for the cooler won’t be open, which means you’re running the transmission low (or in my case extremely low!). The stock thermostatic bypass valve doesn’t open up until almost 180 degrees!!! Max temp for the fill procedure is 122!!

We prefill our units and over filling them on purpose, we then go out and drive it til it’s up to temp do adaptions then drive it some more then I like to check it first thing cold next day time permitting ,

I was told by a prominent trans builder..... OVER FILL the trans !
I literally jacked my car up on passenger's side as high as I could safely get it and got an extra quart in it.
Seems like NO MORE missed shifts at the track!
I also used the Liquid Moly fuid with new oem trans filter. (do any of this at your own risk) just giving my thoughts.

What’s liquid Molly? Can this be used in trans with stock frictions?
