Pontiac Grand Am Will Not Go into All Gears

Question:
Car will drive in 1st and then shift to 2nd but that's it! Reverse is good to. Don't have a scanner and was wondering if there's anything I can just replace. Thanks! 2001 Pontiac Grand Am.

Answer:
By the symptoms you are describing, it sounds like the forward sprag has failed. This is an internal part of the trans. The trans. will need to come out of the car to replace it. Depending on how bad it failed, it may have come apart so that metal has circulated throughout the trans. May need to be totally disassembled, inspected and cleaned, and any other damaged components replaced.

Question:
I have a 94 grand am and it will go into gear but will not move. It started out with just reverse and then did it in drive also. Sometime it will go into drive and when i drive it shifts fine. I checked the fluid level and it is fine. 1994 Pontiac Grand Am Engine size: 6cyl. Check engine light.

Answer:
You have probably set a trouble code with the transmission, and that is why your check engine light is on. If you can get the engine light checked out, it will probably help in diagnosing the transmission problem.

But from what you describe, it has probably been slipping due to age, miles, lack of maintenance, and now it's finally gotten so bad that the car will not move. You are most likely going to need the transmission removed from the car and disassembled to see the exact failure. If debris, metal, or any other material has gotten all around the inside of the trans, you will probably need a complete rebuild

Question: My 2001 Pontiac Grand Am is shifting on 3 now. it used to shift on 2.
 Answer: OK, that is a late shift or it is slipping. Either way, you are going to have to have a transmission mechanic take it for a test drive.

It was overheating over the weekend so i had got a coolant flush and a new thermostat put in. The car has been parked for sometime and had two previous owners. Could i possibly have anything to do with low trans oil?
 If it has been low for a while, then the trans might be slipping, yes

I just found out to check that is by going underneath to check the oil level.
 Yes, that is correct.
