Originally named the "Super Turbine 400" for our Buicks. All GM transmissions with a "400" designation, are functionally identical, save for the Variable Pitch 65-
We believe in the TH-
A few words on the Variable Pitch option.
This is often know as a "switch pitch", which is a term that was popularized by Kenne-
There are two reasons for this:
That being said, don't get us wrong. We love the VP setup for a street car. So much so, we developed the only welded, high quality torque converters on the market now. We are the exclusive provider of Hi Performance VP converters these days.
The VP setup adds a "neat" dimension to your project, and allows the advantages of a higher stall converter, without the excessive heat buildup, and slippage. Itis used for just that in some of the cars we do here. Not because we would encourage you to build a car, with cam timing that REQUIRES it. Even our Level 2 engine can be driven around in low stall, in traffic, with no fear of stalling, once everything is warmed up and "normalized".
A quick word on shift quality is in order here. Generally transmission builders consider a "good shift" to be one that is easy to describe. The engine slows down, and the vehicle speeds up. That's it... And there is not much else to talk about. The shift happens very quickly, and is almost imperceptible, to the driver, under light throttle conditions. With adequate power and gearing, heavier throttle shifts will result in a "chirp" or more, but this is really a function of the speed of the gear ratio change, rather than anything to do with the transmission itself. To put it another way, the engine power, with the ratio change in the transmission, causes the tires to lose traction, as they try to increase the speed of the vehicle.
Often times, and incorrectly, enthusiasts feel that if they have a trans that chirps the tires ever time it shifts, they have a "good shifting" trans. Most transmission professionals would beg to differ. What they have is a unit that someone has incorrectly manipulated either the line pressures in the trans, or the hydraulic control system, which was carefully designed, to allow a wide variety of calibrations, for different applications. Throwing half the check balls of the valve body over your shoulder, and reaming out the spacer plate, and making the accumulators in the trans non-
All our transmissions are built with full metal thrust washers, and complete attention to detail. All steel deep pan equipped transmissions come with a welded in drain plug kit, which is exactly like an oil pan drain plug. Full satisfaction guaranteed. We use only the Trans -
And we don't paint our transmission cases, black, silver, or any other color. Paint is used to keep metal driveline parts from rusting, and last I checked, aluminum does not rust! The real reason transmission cases are painted, is because it's cheaper to paint, than to bead blast. Don't be fooled.
This service includes full disassembly and inspection of the transmission. It is not a full custom rebuild, but rather a re-
