New York Mustangs

My 06 is hard to shift when cold too,1st and 2nd can be a bi--- sometimes. I am using Royal Purple oils so that be the reason. I wouldn't change the trans oil unless you have a lot of miles or it is smells funny somehow.

All manual cars shift harder when they are cold. Changing oils won't change this.

Happens to mine all the time. Just shift slower and within a few miles the tranny warms up enough for smooth shifts. My chevy cruze does the same thing as well as my old 2001 mustang.

I thought it might be the oil, i found it a bit annoyingly weird because. i dont remember my 2001 Gt (R.I.P) having that issue :/. and my brothers G37 doesnt do that neither.

I think you have to be running some serious HP before changing out transmission oil will increase your RWHP. I don't think a stock GT will see any difference. But I could be wrong.
