If im going down the street between 50%-70% throtle and i shift real fast it bogs to the next gear.Not real bad but it makes a quick boging feel and then its fine.And it does it in between every gear. It doesnt do it if im racing and shift fast at redline at wot and it doesnt bog when i shift normal either.So is something wrong here or what?Also do all 5speeds do that jerking thing in 1st and 2nd gear if say your driving throught a parking lot in 2nd gear and floor it and let of it jerks back and forth real bad.

does anyone know why it does this or do all manual eclipse do this?

i'm sorry man but i gotta say this..

Learn how to shift properly!!! We dont' have a torquey V8.. and unless we are high in the rpm band.. u will bog the engine when u shift out of the power band.. so u have two options

1- Shift at higher rpm's, for reasonable acceleration in daily driving i would say 1st 5k, 2nd 4k, 3rd 3.5k.. so on.. that way.. u'r power doesn't really drop below 3k.. obviously red like if u'r racing.

or..

2- ease out your clutch .. this will prevent the "jerking" between gears, and if u do it right, u can even get rid of some of the bogging.

As for the second gear problem, it's cuz u'r prob cruzin around below 2k rpms.. and the engine is trying to go into closed loop.. or sleep mode. Down shift.. or drive faster.. this won't happen.
