Transmission slightly grinds going from 1st to second in the cold...

Upon heating up its fine. Anything I can do to help it? different tranny fluid? or do I have a synch ro issue? **I search the forum prior to posting, lol.

Have you owned the Viper for several years and its just starting to do this now?
or is this your first winter with this Viper?

I'd say it's not that uncommon. I see the same thing in mine and several other non-Vipers I've driven. Cold oil just doesn't grab synchos the same way so you get a little crunch. You might try altering your shifts a little when it's cold, like pulling the shifter slower/faster or more/less pressure on the handle to see if it helps. When it gets really cold around here (single digits and teens) it feels like I'm stirring syrup just moving the shifter around in the gate. Within a few blocks it usually loosens up and feels more normal.

mine does the same thing when it is cold out side. does not like to go in gear easily. once warmed up, no problems. i did , however, changed ALL fluids over a year a go, just in case.

Also, for what it's worth, the T56 in my Dart (reportedly from a 2002 Viper) that is filled with Dexron or whatever the old factory fill was, is much easier shifting. However, that's a much lighter duty engine in front of it (mostly stock 5.7 Hemi), so I don't mind running the thinner oil. For my gen 3 I used the factory Castrol Syn-Torq thicker stuff that I think holds up to the torque of the big V10 better.
