First of all, I changed my tranny oil to AmsOIL and I have similar problems. I have difficulty getting into first gear when I first get going on a cold morning too. What I do is ** very carefully ** let the clutch out, very slowly until it pops into gear and then immediately push the clutch pedal back in. Presto, the transmission is in first and I didn't have to force it. Of course if you let the clutch out too much, you just grind the syncros.

Give it a try.

My mistake *I use that method to get into REVERSE*
