2000 alero gls transmission issue
 

Ok my 2000 alero gls coupe 3.4v6 has no low gear and if you put it in reverse it locks in and won't go anywhere plz somone help

Did you check the fluid level?

How many miles are on this transmission?

Fluid is full and motor and trans has 200k

How about the condition of the fluid?

I don't know for sure about this car, but on my Escort when you move the shifter, it's really pulling or pushing on something that looks like a bicycle cable, which operates a lever on the transmission. Can you verify that's working on your Alero, if applicable. Things like defective mounts or brackets can interfere with this.

Also, if there a way to check the transmission fluid pressure, do that. You could easily have a transmission oil pressure problem. I know on my Escort, the transmission oil pump is mounted on the side of the transmission and is easy to get to once you remove a tire and the plastic wheel well cover. I show the transmission oil pump for my Escort here:

If you have low transmission oil pressure at idle, your car is going nowhere.

I know at 200K you probably think it's worn out, because it probably is, but for what it costs to do what I suggest, it's at least worth doing for educational purposes. If you have a factory service manual (and you should, they are cheap used off of eBay) it should tell you how to do transmission tests. I have 224K miles on my 1995 Ford Escorts original automatic transmission (I bought the car new) and from what I can tell, a lot of people throw away a transmission that needs a simple repair because they for some reason don't want to repair their automatic transmission, but a lot of the time a simple fix, like this one can make your transmission work again, for years:
