  TH400 Level 3 – “ 400 Raptor ”

The level 3 high performance TH400 transmission comes with a Fairbanks TransAction Shift Kit for firmer shifts and more holding force on all the clutches. The front band is replaced with a wide Alto Black band. The stock intermediate sprag is replaced with a 34 element sprag with over twice the holding power of the stock sprag. Some of the other features are Kolene Steels and Red Eagle Power Packs in all three clutch sets, extra hard input shaft and drum and an extra hard forward clutch hub. You get your choice of a 4 inch or 9 inch tail housings plus your choice of three different length 4WD output shafts. All transmissions come with a free PATC shirt. This transmission will replace your 4L60E or T56 transmission on 1998 to 2002 F-Body Camaros and Firebirds with LS1 high horse power nitrous motors. Good for motors up to 1200 horse power.

CommentsWhen ordering a 4WD TH400 transmission we need to know how far the output shaft sticks out past the case. If you  have a 454 motor the #7 torque converter that comes with the level 2 TH400 will require a dual bolt pattern flywheel.
