Replying to: burdawg (Mar 26, 2007 8:18 pm) i have a 2001 grand am, two weeks after i bought it, it started shifting like the trans was comeing out. it would shift very hard when the car got hot, or if i sat still and the car was running. i worried with it for 4 or 5 months and had it scanded every week by all the auto zones/ advance auto stores in my town they all had something differnt to tell me. finnaly i went to the dealer, they put it on the dealer computer scanner and it was a vacume leak on one of the little plastic hoses around the mass air flow sens. got it fixed and been running fine for 4 years now... good luck
#15 of 51 '99 Grand Am "chugs" between 2000 and 3000 RPMs by gase Jun 16, 2007 (5:33 pm)
I have a '99 Grand AM SE and for the past two years it has chugged slightly with strain, ie: on inclines at speeds around 60+. I took it to a shop originally and it was found to have problems with the spark plugs and housing unit- these were replaced and the problem improved, but did not resolve. Two days ago I had the computer checked and nothing was found to be out of order. Today, however, it has gotten much worse and now in order to maintain higher speeds I have to manually downshift on any inclines. Also, the service engine soon and trac control light came on today. Anyone have any ideas? Replies to this message: krs01grandam (Jun 20, 2007 11:36 am) okko1 (Jun 24, 2007 6:24 am) red_fox (Jan 01, 2008 6:38 pm) Jswen (Dec 30, 2008 7:17 am)

Replying to: gase (Jun 16, 2007 5:33 pm) my catledic converter went bad in my car about 8 months ago, sounds like that might be the problem. it had gotten clogged , and wouldn't hardly go when i gave it any gas at speeds of 30 and up... Replies to this message: okko1 (Jun 24, 2007 6:24 am)

#18 of 51 2002 Standard Grand AM - won't go into reverse by wveagle Aug 21, 2007 (9:02 am)
I have a 2002 Grand AM thats standard and to get the keys out of the ignition it has to be in reverse and now it just won't go in reverse most of the time. All of the other gears work (1st, 2nd, 3rd, 4th, & 5th).
#19 of 51 96 Grand Am GT 2.4 transmission trouble by nauticaboy025 Aug 26, 2007 (2:02 pm)
I have a bit of a problem. I have a 1996 Pontiac Grand Am GT with 150,000. A month ago my dad changed the filter and fluid. After this was done when I would first start the car I would have to let it run for a minute or it would really bog down for it to move. Once it ran it was fine. Yesterday I was on the highway when I realized the rpm was going up to keep it going at a steady 70 and then I lost all power to the transmission. After it cooled it would move but still strain. I did this to get it home. You could also smell the fluid burning. After it cooled over night I started it and and it seemed to work normal. Is it time for a new transmission? Could the filter and fluid change have caused this? Until now I never had a problem with the transmission. Any input would be much appreciated.
#20 of 51 GM 4T60E Transmission has no 4th Gear by ron528 Aug 28, 2007 (12:13 pm)
I have had a 98 Pontiac Grand Am for about 2 weeks now. It has the 2.4 liter 4 cyl so its suppose to have the 4T60E transmission. Well it won't go into 4th gear at highway speeds. First day I owned it the engine wiring melted and the dealer replaced the engine wiring harness.   First, secnod, and third gears wortk fine. Fluid looks and smells good. What could cause this transmission not to go into 4th gear? It tachs 3,000 rpm at 60 mph in third gear, when I put it into drive, still at 3,000 rpm at 60 mph.   Any help will be greatly appreciated!

#21 of 51 02 GT: transmission? by kbright2 Sep 23, 2007 (8:32 am)
I have an automatic 02 Grand Am GT sedan and recently it has started making an unusual humming sound and it's giving me trouble in shifting up, usually taking effort to go over 25 mph. So far no overheating, etc... just not wanting to go. Does it sound like the transmission?
