I have a 2015 ram 3500 with the Aisin, not had it long.

This truck pulls awesome, runs great and rides great.

I am only run with stock running because of the shift flares.

Only pull obviously with stock tuning.

My problem is that if the truck sits for more than 2 days when I first startup it will take about a minute before it will move once I go into drive.

Its just like the torque converter has had all its fluid drained out of it and needs to build that back up to move.

After that it pulls and runs perfect.

If I park it today tomorrow morning not a problem and this just came on since the warmer weather or now since I don't need to warm it up as much.

Anyone have a similar issue?
