I’m having a problem with my 4th gear not engaging in higher speeds. It pretty much feels like it’s in neutral. Weird thing is if i’m just cruising around the city rolling through the gears normally, 4th gear will engage. But on freeway speeds, once I go into 4th, neutral. On a stop, if I try to take off with 4th, it’ll actually let the car roll (Just tried it out to make sure my 4th wasn’t shot) Any ideas what this could be?

 

There is no issue with other gears on low/high speed? No grinding noise while engaging?

 

what does the oil look like?
