Boost Logic's GTR Transmission Overflow Can gives you the ability to over fill your transmission with fluid.
 
When air is introduced into the transmission oil pump, it has the potential to cause shifting issues; this will help to prevent air from being sucked up by the transmission oil pump during hard accelerations and spirited driving.
 
The overflow can mounts on the right side of the vehicle, just behind the rear fender liner. Simple install utlizing factory hardware.
