96 Grand Am GT 2.4 transmission trouble by nauticaboy025

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.

GM 4T60E Transmission has no 4th Gear by ron528

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!

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?

Exact same problem with a 2001 Grand Am.
Today the check engine light and ETS (traction system) lights came on while it was trying to shift out of overdrive on the highway.

passenger side driveshaft bearing noisy by mcallan1

Hey all, I have a 2000 Grand am gt. Has anyone ever had the problem of the right side driveshaft bearing growling and noisy? It recently has had both front wheel bearings replaced, with the right side being real difficult to get off. Wondering if this was the start of a bad transmission bearing????? And is it something that can be changed from the outside?, or does it have to come out and apart?????

99 GA 3.4 Tranny Noise and loss of all gears... by ken74

Hello all:
 
First a little background on the car...
 
I had just replaced the struts, rotors, pads, and front tires the day before this failure occurred. Where does this tie in to my problem? Well, it may or it may not. I'll get to that later.
 
The day after the repairs I was driving along at about 45 enjoying my new riding car. All the sudden the car tached-out as if I had knocked the shifter into neutral. However, much to my dismay, the car was still in drive. I coasted to the shoulder and turn the car off. After scratching my head for a minute I restarted the car and tried all the gears; none of them responded. I did however note a metallic-zipping noise that occurs in all ranges to include park.
 
I checked the shifter cable and it appears to be actuating the shaft on the tranny. The fluid is good.
 
Another thing I noted is that the whinning/zipping noise will go away above 2500-2700 rpm.
 
Any thoughts?
 
Ken

If the noise is in all ranges then the most likely cause would be that the pump is damaged or the filter is clogged with debris from internal damage from somewhere else.
