I had a 88 myself and had the same problem, look down inside the console by the shifter and there is probubly change that has fallen down there. Hope this works for ya
There are a few more things that can be wrong, but the most common seems to be the shifter cables. The 88 GT came with 2 cables, both of which are NOT adjustable (and stretch with time), and no longer available to purchase (stock). As they stretch, they lose effectiveness. You can buy replacements that are adjustable (and come fairly accurately adjusted) from RodneyDickman.com. Good luck. I had no one to get advice from and spent a TON of money having my hearbox torn open twice to replace all the gears and synchros before I finally figured this one out. Don't make the same mistake.
Gear up then

All years of Fiero heater cores are the same, with the only difference being A/C equipped or non A/C equipped. Go to fierostore.com and you will find what you are looking for.
synchro plates went out
sounds like the coil need to be replaced olds 88's have been known to have that problem
my 94 Toyota corolla will not go into any gears .
The clutch is bad or out of adjustment.
bad transmission..... expensive repair.
Most likely a broken gear cluster
if you mean it wont go into gear and it grinds like a sob but other gears still work synchronizers. if you mean the shifter is loose an cant find the gear anymore - linkage. if it wont go into any gear sounds like a clutch problem
My first suspect would be the clutch. Have a competent mechanic take a look at it.
