 High Performance
TH400 Street / Strip Transmissions

Level 2 - 400 Terminator

 

 

 

The level 2 high performance TH400 transmission comes with a high performance Fairbanks TransAction Shift Kit installed for firmer shifts and more holding force on all the clutches. The front band is replaced with an black carbon fiber band. The stock intermediate sprag is replaced with a 34 element sprag with over twice the holding power of the stock sprag. As part of this package deal you get a heavy duty / high performance balanced stall converter with furnace brazed fins and bearing construction for added strength (#7 see below). This torque converter stalls at 2600 RPM for a faster take off. We also have this same converter in 1800 and 2000 stall speeds. You get your choice of a 4 inch 32 spline (bolt-on yoke or not) tail housing or a 9 inch 27 spline tail housing. When ordered with the 9 inch tail housing and 27 spline output shaft your drive shaft may be able to be reused by making it shorter. It comes with an intermediate 4 clutch Power Pack. Good for motors up to 800 horse power (transmission). Upgrade the torque converter if you have over 400 horse power. All transmissions come with a free PATC shirt. We ran one of these in our 1200 horse power drag truck for three years before it finally broke a gear and that was without the intermediate Power Pack. (We've tested 400 transmissions against 350 transmissions and the 400 transmissions were faster.)

This high performance 400 package deal can be yours for $1549.00 without a trade-in. The freight charge to you will be $50.00 to $200.00 in most cases after the freight discount. This is a 2WD transmission, add $100.00 for 4WD case.
