I don't think there is any shifter linkage to adjust on a manual transmission Tacoma. All transmission components other the the shifter are enclosed within the transmission housing or tailshaft and have no adjustments. You mentioned it happened after a snowstorm, have you craweled under the truck and carefully looked at the transmission for for signs of oil leakage or any type of damage? Also check that the oil level is correct.

Although I don't think your clutch is the problem it's a good idea to make sure the clutch master cylinder has fluid in it. I think you have an internal transmission problem meaning it has to be removed to correct the problem. Worn or broken parts are probable causes.

I'm assuming your truck isn't out of warranty due to mileage, take it to your dealer, they should repair it under warranty.
