When cranking up after running it will not go forward until the engine is warmed up, why?

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. Sounds like an internal hydraulic transmission concern. There is probably a concern in the valve body or otherwise that benefits from higher temperatures. I'd recommend an assessment at a shop near you but an educated guess is that you'll need transmission repair, overhaul or replacement. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
