Greetings all. I'm new on the Forum. I'm on my 2nd Subaru. My 1999 Subaru Legacy Outback (112K miles) is very slow to engage when shifting from Park to Drive. There is no delay when shifting from Park to Reverse. When cold the delay in engine engagement from P to D is only brief; however, when the car is warm, the car sometimes does not engage at all until I lightly rev the engine. I checked the automatic transmission fluid level and it’s fine. What might be causing this? Thanks in advance for any advice!
