I JUST GET THE BEAUTIFUL 2004 - 215-hp, 3.2-liter V-6 (premium), 5-speed automatic w/OD MODEL, AND MY FIRST QUESTION IS, WHEN I TAKE THE SPORT SHIFT ON THE TRANSMISSION AND I PUSH THE FULL GAS, SOMETIMES, (MOSTLY) WHEN THE GEAR SHIFT BACK, THE ENGINE JUMP, AND AFTER THE TRANSMISSION SWITCH TO THE (N) I THINK, BECAUSE ONLY THE RPM MOVE,... AND I ALWAYS PULL DOWN, TAKE BACK THE (P) AND AFTER AGAIN THE (D) AND WORKING GREAT...SO THIS WEIRD, THE COMPUTER DIDN'T MAKE ANY SIGNAL...I HOPE SOMEBODY KNOW WHAT THIS...

TAKE CARE - DRIVE SAFETY
imo

 

First thing you should do is search here on checking the transmission fluid level. This is a symptom of low fluid level.
Also check the transmission connector for leaks.
At worst, you may have a bad conductor plate, there is also a DIY on that here on the forum.
Most likely not the TCM ( Transmission Control Module ), but one can never be sure.

 

Thank You - ala_xfire,

I will check the transmission fluid level, and the connection either, i hope only this is the problem, and thanks a lot again...!
