Only Available as an Upgrade for Our Paramount Performance A8 Transmissions! 

Lower your A8 transmission temps from the CRAZY 197°F to 160°F!

It will gradually warm up to 160°F. We never recommend removing the thermostatic valve as it slows the fluid flow down to the proper flow through the stock cooler, which seems to be adequate at this point.

Imagine the benefit of leaving the starting line at 160F compared to 195F! This will help your transmission fluid life. It is not sold separately, only available with the Paramount A8.

Note: If you have already purchased an A8 from us, we will be happy to sell you this part individually! Please send us an email to containing the serial number of your Paramount Performance A8 transmission as well an a purchase receipt or invoice.
