SLIVERADO SIERRA ALLISON 6L80 6L90 8L90 COOLER BARBELL THERMOSTAT BYPASS PLUG

Description

You are buying a custom barbell that installs into the factory thermostat housing to eliminate the factory thermostat.  This barbell forces the transmission fluid to go through the factory cooler 100% of the time resulting in:
Lower fluid temperatures
Extends transmission fluid life
Full time cooler flow, regardless of operating temperature
Instant fluid level check, so no more waiting for the trans to warm up and then cool down before fluid level check.
This fits:
Some Allisons from 2017 to 2019
6L80 & 6L90 from 2014 up
8L90 2016 up
It is very easy to install, if you need instructions contact us.
Shipping will be USPS first class mail, priority mail optional.  Feel free to contact us if you have any further questions.
