RPMs drop upon initial acceleration?
Might someone be able to help me figure out why when I apply pressure to the pedal to accelerate while cruising, the rpms drop for a second almost 200 revs? Its the strangest thing ever!!!

Nope, its when im already cruising and i move to accelerate, as soon as i push the pedal down, no matter what amount, the rpms drop for about 1.5 secs. Thanks for the quick reply, I hope they keep coming

Mine has always done that (and I've had two transmissions). Other people have noted it as well. Why it does it I don't know.

Maybe something to do with the TC locking up?

I've noticed that if the RPMs are at ~1.2K or less, it may drop down (like it's hunting for gears or something). It does not do this while in first gear. It does happen in fourth gear with the TC locked up; it's noticable (you can feel it) but you can't really see it on the tach.

Is the transmission down-shifting when you push the gas? It could be the ECU/TCU dropping RPM to smooth the shifts.
