Default Rear Axle Question?

Hey everyone, I Was reading my build sheetJust trying to learn more about my Truck, I understand the Anti-Spin Diff is the same as limited slip, but what is meant by Lock-Up Torque Converter? is this the same on all Rams or is it an added option?Thanks for anyinformation.


DHAP - Lock-Up Torque Converter
DMHP - 3.92 Axle Ratio
DRBS - Corporate 9.25 LD Rear Axle
DSAP - Anti-Spin Differential Rear Axle

A lock-up torque converter does exactly that, "Locks up" into gear to provide overdrive. It can be mechanically or electronically activated. Most are electrical anymore.

the lockup torque converter is good... the lock-up is not required for a torque converter.... Read this "How Stuff Works" and you will know how it works.... the "Lock-Up" is a special added feature... after reading the information you will understand that Essentially the engine is COMPLETELY disconnected from the tranny.... it uses fluid coupling to spin the tranny. So the engine is usualy spinning FASTER then the tranny most the time... read below:

At higher speeds, the transmission catches up to the engine, eventually moving at almost the same speed. Ideally, though, the transmission would move at exactly the same speed as the engine, because this difference in speed wastes power. This is part of the reason why cars with automatic transmissions get worse gas mileagethan cars with manual transmissions.
To counter this effect, some cars have a torque converter with a lockup clutch. When the two halves of the torque converter get up to speed, this clutch locks them together, eliminating the slippage and improving efficiency.

In answer to yoru question.... It is standard on 3rd gen5 Speed and Multi-Speed Overdrive Automatic Transmissions. Other trannies do not have the lockup for example... The ramV6 has a 4 speed tranny and NO lock-up feature.
