I currently own a 1990 Volvo 240 DL (151k miles) with a 3 speed automatic transmission and 4 speed overdrive. I'm able to select the next lowest gear while driving and blip the engine to match the tranny speed, which I've heard many many people tell me is "uncommon" and "very cool." As much as I enjoy doing this, considering I have a straight pipe exhaust installed, I never cease to wonder if this type of blipping isn't supposed to occur. I always make sure I have the correct type and amount of fluid in the tranny, and regular upshifting seems perfectly normal. Left to its own devices (meaning, when I don't blip the throttle), the tranny downshifts just fine. Is this type of occurence common in most other automatic transmissions? Has anybody else discovered that their car can do this too? I've tried this same thing in a few other cars with slushboxes, but mine is the only one which can. What's up??<P>-Beefy

I guess I don't get what you are saying by "blipping". I've recently learned if I stomp on the gas, my auto tranny in our '90 245 will downshift and roll on out to near redline, which is a lot nicer than when I was being easier on her...

cant say ive herd of that before.so what your saying is that your kinda doing the manuel trick, say for example: cruseing in 4th gear, need to overtake. clutch in,push gas pedal quickly(the 'blip')to get the box up to speed. by this time you have changed to 3rd.out with clutch and flying past the guy.? right?BUT, you have and auto with OD. your cruseing along pull the selector to 2nd or 3rd?? the car wont slow down cause you are going to fast, so you stomp on the gas and it kicks down and revs higher giving you more pulling speed?? is this right? autos are pretty robust, the only real way to kill one is if you are pushing to many hores throught it or you like pulling it to drive from reveres before the car stops.<P>michael.<P>

Hey George, your monster wagon doesn't chirp the tires when it slams down a gear, does it? <IMG SRC="http://www.swedespeed.com/ubb/biggrin.gif"> That would be so cool!<P>There were a couple of times when I first had my car and was learning to drive stick when I downshifted while braking and locked up the tires for a moment. That got my attention!<P>

George, to answer your question: By "Blipping," I mean heel-toe downshifting. I am able to do this type of shifting in my auto during both accel and deceleration. Whenever I select the next lowest gear, say from 3rd to 2nd, there is a very slight lapse in tranny respnse, say about 1/4 to 1/2 of a second... just enough time for me to match tranny speed with engine speed, making everything match up nicely. Produces a nice sound from the exhaust, too. You guys would be surprised how hardcore a B230F sounds with no muffler!<P>-Beefy
