the grind..., please help Options

[i_wanna_go_fast]

So heres the problem....

My gears grind.
The clutch is good.
Press in the clutch... to the floor, let off the gas... or vice versa... guess it depends on the driver... but either way... if i dont let the rpm's drop down low, the gears grind. doesnt matter what gear. doesnt matter if its up or down. only thing that matters is the rpm... if its higher they grind, if its low say below 2500 they don't. cant give an exact number cause whoever had the car before me put in new gauge faces and messed up all the needles...

could it be a flywheel issue?
shifter needs adjustment?
fluid change?

please help!!!!!!

so.... i think maybe this guy knows what my problem is... anyone know where i can get a heavy duty set of gears???


"take to reputable transmission shop to get it diagnosed and repaired. it sounds like the synchronizers are a problem there. and you may have metal in your fluid now that it's been grinding which will affect the rest of the transmission. if you are speed shifting as in racing, you are not doing your transmission any good. you probably don't have a transmission built to do that if it's the original factory tranny... meaning you did a major NO NO to your tranny and are tearing it up speed shifting when it isn't built for racing."

Use Pennzoil Synchromax or Royal Purple Synchromesh.

X2 on the fluid, but it does sound like a syncro problem

Synchros shot. Rebuild time. Or learn to double-clutch.

As a test, have someone who is good at double-clutching drive the car. He/she should be able to shift without grinding. If they can't, I'm wrong.

Are you sure the clutch is good? I had a Mustang that showed pretty much the exact same symptoms, hard to shift, etc. Clutch was brand new, turned out the pressure plate was messed up by whoever installed it and wasn't allowing the clutch to disengage fully. I would at least see if you can adjust your pedal to make sure you are releasing the clutch fully.

Otherwise try Synchromesh fluid before you jump to conclusions about rebuilding or replacing the tranny, can at least give it some extended life.

You can test for clutch dragging (not disengaging fully). Start in neutral. Then pedal to the floor, put in gear. If it's dragging, engine rpm will go down.
