Auto Tranny

[HaLo]

Hey guys,

A friend of mine owns a 1991 240SX SE with auto tranny (bone stock).  I tried it myself and I'm quite perplexed.  When you floor the gas pedal, you hear a small "click" from somewhere underneath the dash and the car jumps forward and shifts at the redline.  If you don't floor it, you don't hear that click and it shifts between 2500-3000 rpm.  The power output surprised me: my manual 1993 240sx (intake / exhaust) feels more powerfull, but not much. To compare this, I have tried an auto tranny on a 1993 LE model: it doesn't not click and does not feel as powerfull (the guy as unorthodox pulley on).

Could someone give me explanation on this "click"?  Is it possible the auto tranny on an SE and LE aren't the same?  Would it be that the previous owner played in the gear ratios of his auto tranny?

We have found an independant tranny cooler, could it be the cause of this "performance" feel?

Also, I was arguing with friends that an auto shift is quicker that a manual shift (I'm talking about the process of switching gears).  Was I right or wrong?

Look under your hood, there is a little connector that controls the auto tranny shift points. But when you disconnect this guy, it makes the car shift "harder". Perhaps it is disconnected? Look on http://www.240sx.org in the FAQ, they have a good explanation of the auto shift connector.

your friends 91 feels quicker because it is quicker he has 91 cams you don't. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/sad.gif" border="0" valign="absmiddle" alt=''> plain and simple. If he had a 5 speed in the car it be even more noticable.
As far as automatics being faster yes and no.
Stock automatics tend to be slower than manuals in acceleration,but technically they can shift faster.
So if you had an auto with a hi stall torque converter and a shift kit you could kick some ass in the quarter mile with an auto and mods.
