I've got a 96 Accord LX, 103,000 miles, manual transmission. Yesterday after the car sat for a few hours in the cold (upper 20's) it didn't want to shift into gear, any gear, directly upon starting it up. After working it it would go into gear with a little effort. After getting it on the road and driving for a minute it would then shift just fine, silky smooth with no effort just like it always has.

This morning it did the same thing, didn't want to go into gear upon startup then works perfectly after driving for a minute.

My first thought here is the transmission fluid as I can't recall the last time (if ever) I had it changed or even checked. Is this likely the issue?

Thanks for any suggestions or thoughts,

Jack
