High Performance
400 Street / Strip Transmissions
|
|
Level 2

|
This high performance 400 transmission comes with a high performance Fairbanks TransAction Kit installed for firmer shifts and more holding force on all the clutches. The front band is replaced with an Alto Kevlar 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). 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 $1449.00 without a trade-in. The freight charge to you will be $50.00 to $200.00 in most cases after freight discount. This is a 2WD transmission, add $100.00 for 4WD case. |

#1-350. TH350 elevated pressure valve. The OEM boost valve sleeve wears out from the reciprocation of the steel valve within the aluminum sleeve. Wear in the reverse boost sleeve results in low line pressure, soft 1-2 and 2-3 shifts and/or reverse engagement or shudder. Sonnax now offers a high performance boost valve and sleeve replacement. This new high performance boost valve and sleeve incorporates a larger boost ratio which increases line pressure and provides firmer shifts. It is also recommended for street/strip performance vehicles. Cost $49.00 |

#2-400. Fits TH400 transmission. Boost valve wear results in oil leaks and poor line rise. This “Factory style” reverse boost valve and sleeve is manufactured from hardened steel to prevent wear. Vehicles with a TH400 transmission frequently have poor line rise, soft 2-3 shifts, and/or reverse engagement difficulties. These problems can be caused by the reciprocating reverse boost valve wearing the inside diameter of the boost sleeve. When this occurs, oil that enters the modulated throttle valve orifice leaks past the boost valve and exhausts through the reverse orifice or to the sump, resulting in poor line rise. Also, reverse oil can exhaust both to the sump and back through the modulated TV orifice. The outside diameter of the boost sleeve also allows some leakage through the pump body, which can increase boost oil loss. Cost $35.00 |

However, the elastomer material wears, reducing the size of the ball. Fits 700R4, 4L60E, 200-4R, TH350, TH400 and 4L80E transmissions. Sold 10 per bag. Cost $7.00 |

#61XXX. This kit is for installing a TH400 short tail, 350 or 200-4R transmission into a Third Generation F-Body. The kit includes the transmission crossmember required to install the transmission, along with our crossmember mounted adjustable torque arm. The TH400, 350 or 200-4R transmissions have no provisions to mount the OEM torque arm onto the transmission tailshaft. Our kit makes the swap an easy bolt right in installation! Cost $500.00. Torque Arm Rear Mounting Hardware Kit - $20.00 |

#62. The OEM case bushing in vehicles with a THM 400 or 4L80-E transmission tends to “walk-out” of the housing bore. This allows the bushing to wander into the extension housing, leaves the output shaft unsupported, and may ruin the governor gear. The cause of this problem is the lack of a flange or “stop” surface on the case bushing to prevent the “walk-out” from occurring if the bushing begins spinning in the bore. Cost $8.00 |
|
![]() |
|
#62S. It is often difficult to reduce front unit end-play on TH400 or 4L80-E units with excessive spline wear. Normal component wear allows excess forward and direct drum travel. This travel or free-play reduces sealing ring life. The TH400 and 4L80-E are limited on the thickness of pump shim material that can be added. Excessive shimming at the pump will push the forward drum off the rings and result in a burned forward clutch. We offers a .010" thick shim, part number 62S, that can be stacked under the sun gear bearing race. Cost for 10 shims, $6.00 |

|
|
|
#66CS. TH400 Oversize Intermediate Piston and Center Support. If your TH400 transmission is being used in high power applications e.g. Supercharged, Turbocharged, Nitrous or Mega Cubic Inch engines, you need to look at every area of the transmission to boost your performance. The intermediate clutch apply piston has been increased in size by 9.1%. The size of the center support piston and bore is .250" larger. (stock piston is 5.617" - this piston is 5.867" diameter) The increased diameter applies more clamping force on the second gear clutch pack, reducing the possibility of driving through the clutches as the power curve comes on strong.

This allows front unit endplay to be reduced. - - - - The new .030" thicker 34301-094 thrust washer is an alternative to the OEM washer. Shimming at this location maintains the relationship with the forward clutch hub and direct drum and does not alter the endplay path through the unit. Cost is for one thrust washer.

Electronic Ratio Adapter (ERA) Now You Have the Solution to Your Speedometer Problems..... |
![]() |
#69. Any change in a vehicle's tire size or rear axle ratio will cause the speedometer reading to be inaccurate. The Electronic Ratio Adapter (ERA) is designed to correct this problem. With the ERA, you simply hook up four wires, set the DIP switches according to the calibration table included with your order, and you are ready to go.
What does the Electronic Ratio Adapter do?
The automotive industry has a great variety of part sizes, types, shapes and descriptions, but regardless of make, model or year, a few things are standard. One of those standards has been the number of revolutions a speedometer cable will make for each mile travelled. Nowadays, electronic pulses have replaced the rotating cable, but the same principle applies. The Pulse Ratio (the number of pulses per mile travelled) remains the same, regardless of speed, since the same distance is travelled and the same number of pulses have occurred each mile no matter what the speed was during that mile.
However, this Pulse Ratio can be made to vary from the true when modifications are made which change the number of electronic pulses per mile on a particular vehicle. This is most commonly caused by changing the tire size (increasing the outside diameter of the tires will cause the tire to travel further before making a complete revolution), but other modifications could have the same result. When the Pulse Ratio is thrown off, the speedometer/odometer will be inaccurate and corrections must be made.
This relative difference between true speed and the speed indicated on the speedometer is called the Variance Ratio, and it is corrected using the Electronic Ratio Adapter. Cost $149.00
