Well let me start off on introducing myself. I am 17 and I have a 93 Corsica 3.1L V6 @ 167K. In adittion to that.. my name is Blake andI love working on cars and find that I am pretty knowledgeable for my age when it comes to automobiles. This looks like a great site and I am hoping to add this Forum to my favorite list. Okay..next.
My 3spd auto has been giving me some slight problems. First off let me say that when driving the car normally it shifts fine and isn't sloppy or anything. But when I drive it really hard for maybe 15-20 mins, or if I am in hot and heavy stop and go traffic, that is when it starts giving me problems. When I am coming to a stop the car will downshift to 2nd when it's suppose to but not 1st. Its like it forgets but then it tries sometimes. Sometimes it will catch itself, but if it doesn't, then I must downshift it manually via center console shift knob. Sometimes even if I catch it and downshift myself, its like it doesn't do it all the way. You can feel the car trying to move as I have to mash on the brakes. Then the SES light comes on and throws a DTC 33 which is a High Manifold Absolute Pressure. And when that comes on usually when I go to start off again the car will make a whole bunch of griding noises until it shifts into 2nd. No obviously the car will stall if I don't nor the car itself catches it. Now the only way to start off when stalling for me is a nuetral drop. I have tried putting the car in nuetral then starting it and then drive and it will stall. I have tried putting it in park and then starting it and then putting it in drive and it will stall. So the only way for me to get it going is to do a partial throttle netural drop. Of course I don't do a really heavy nuetral drop.
Now has anyone experienced any symptoms like this? I was wondering if there is any cable to maybe try and adjust. Maybe a certain trans cable expands a lot when it gets hot or something and causes a lot of slack? I highly doubt that since all my cables seem to be just fine. I was thinking its also probably a 2-1 shift selonoid. Oh..the car will still do this even if its a normal temp but I have been running it hard. Well thanx guys for reading this, I know it was a long post. If anyone has any suggestions please comment on this. Thank you.
