The trannys they used are a POS. Convert it to a manual and you will enjoy your 7 much more.

yes this is normal. The transfer of motion between the engine and tranmission is done through a torque converter (do a search at www.howstuffworks.com ). Basically, its full of fluid, and once the fluid get rotating, which is done by the engine, it will cause the tranny to rotate. It takes time for the fluid speed to catch up to the engine speed, so you see the effects on the tachometer. Engine speed revs up but car speedometer takes a while to catch up. A manual transmission has a clutch, which is a solid friction disc. When it is engaged, the transfer of power is more instantaneous.
