If you're not experiencing a burning smell, it's most likely a clutch adjustment. The clutch appears to remain partially engaged and without adjustment, will eventually burn out. A symptom of this would be the RPM's being higher than normal when shifting.

Transmission will not go into any gear


Stick a magnet on your pedal and if it doesn\'t stick then it\'s the OEM pedal and should be replaced with the steel pedal.

Pontiac had this \'awesome\' idea to make the clutch pedal out of aluminum and after 20 years the pedal actually starts to bend and bottom out on the floorboard before giving you all of the travel necessary to disengage the clutch. Fierostore.com sells a replacement pedal for about 50 bucks. This is the first place I would start since it is what fixed my 1986 Fiero GT 4spd.

If the problem is still manifesting then move onto bleeding/replacing the clutch master/slave cylinders.

I\'ve also seen the brackets on the transmission that the shift and select cables attach to have worn out and introduced a bunch of slop in the shifter, but this is less common.

I\'ve also seen the clutch release bearing seize because of a broken release bearing fork slipping around the collar and grabbing the freely rotating part of the bearing. This then leads to pressure plate fingers breaking off and soon no matter how hard you push, the clutch won\'t disengage. Tranny has to come out. Seen this once.

And last but not least, I\'ve also seen a nut on the inside of the transmission shift/select shaft come loose and leave the tranny stuck in the 3/4 fork. Seen this one time 5 years ago.

Good luck,

Maybe try to press the brake pedal and run the gear shift throughout the full range of gears while the car is on level ground, and retry the starter to see if there is a faulty PNP adjustment.

Try to start in Neutral not Park, and jiggle the gear shift back and forth to see if the PNP is not adjusted right.

Good luck on this repair.

Ok my 1986 Fiero 2m4 wont come out of reverse it was hard 2 shift gears all day yesterday until about 4 o clock now the transmission shifter just moves around freely but like i said its stuck in reverse...


Manual or auto?

It's gotta be the cable/linkage. You just have to inspect them and see if something is worn or snapped. They get old and crusty and need to be replaced eventually. I had to replace my shift cable on my 86 se with the 5-speed getrag.

Hopefully it's not the actual tranny....?

My 86 Fiero SE clutch master cylinder is weeping


Replace it. Not a difficult job. Be careful the bracket on the V6 4spd. isn't strong so don't break it while loosening the slave cylinder retaining nuts.

Good luck,

1985 fiero been having problems getting in gear. Now wont turn over starter. New starter didnt fix problem. Dont know if 2 problems are related. Can push start.


Have same car, same problems, easy solutions.

Getting into gear has been improved by putting in neutral with engine running to warm up fluid. The Fiero has very little room in the pedal area. I'm shifting a lot better with smaller shoes.

The problem with starting may well be related to the same issue. There is a neutral safety starting switch. If you're not pressing hard enough on the clutch - starter won't run. According to the Fierostore.com stock clutch pedals tend to bend. They sell a stronger replacement.

My Fiero has been starting just fine the last few days. The last time it didn't I was wearing boots.

I've almost always been able to get it to start using a booster battery, but Walmart's tester indicates that the battery and charging system are fine. It recommends tightening connections. I did this, but still had problems for a while.

What engine? Rear wheel drive ?Sounds like shift linkage or cable out of adjustment slightly. Have a look at where cable or rod attaches to transmission for adjustment. If not sure of what your looking for get back to me with info.
