Rudy's has bundled the perfect service kit for your G56 transmission!  G56 transmissions are strongest and most popular manual truck transmission of all time.  There are a few downfalls to the G56 transmission, though.  The transmission fluid and how it's cooled.  Unfortunately, there is no active cooling measures on a G56 transmission.  Rudy's now offers a top of the line cooling add-on for your G56.  Fast Coolers PTO extensions allow the fluid to be actively cooled during operation.  With the Fast Coolers PTO extensions, you can increase fluid capacity by over 40% and reduce the temp on your trans by over 30 degrees.  This kit also includes the updated Mobil 1 SAE 50 transmission fluid for your G56.  Which helps with bearing, gear, synchro life.  It also helps with the infamous rollover noise created by the G56 transmissions.
