Help?  I am having trouble trying to get my 4 spd into first gear.  I can engage the clutch and engage all gears except first gear.  When I let the clutch out, it pops out of gear and grinds.  This is the only gear that this happens in.  Over the weekend I took the Hurst shifter loose, but I did not disconnect the linkage.  Any suggestions or is it time to rebuild?

Thanks,

Steve

It is either not going fully into 1st, or there is internal wear/damage.
Did you have this problem before you took the shifter loose? If not, a simple linkage adjustment should cure it.

If the problem was there before, then you probably have internal problems. That could range from a worn shift fork, to a worn gear/coupler.

It's unusual for 1st to have worn synchro teeth, since it is not a "shifting" gear, but, it could happen. There could be excessive end-play, also. Unfortunately, if the linkage adjustment doesn't solve the problem, it will need to be removed for repair.

Thanks for the feedback Joel.  I didn't have this problem originally.  I didn't want to start adjusting the linkage, because I never took the linkage loose.

Just moving the shifter(unbolting it) can upset the adjustments. Since it normally bolts to the crossmemember, and not the trans itself, it could very well just be in a different location than it was before. Don't take much to create an adjustment malfunction. Sounds like adj. time.
Whew! Could be worse!

It is actually a Hurst shifter that bolts to the transmission.  That is the reason I am suprised that it would need to be re-adjusted.  But I will start there and hope that is all it is.

Thanks,

Steve
