Hello sir , I have a 2019 Honda Accord LX currently with 77k miles , recenlty after engine oil i also did spark plugs , I keep my engine oil up to date every notice I get of 30% life , a couple days after doing my spark plugs I was getting vibrating/ jerky driving effects , I parked my chargers removed new spark plugs to test , after I attended to drive my car did not move , I then thought it needed transmission oil , so I did a flush and replaced transmission oil , i got a new transmission at 28k due to vehicular running over something over the road , so my engine oil was right around the low level , when I removed the old engine I only noticed 1quart and 3/4 full for other bottle after watching your video as well , after I dropped it it still did not work , now it’s at the dealership and they will Charge me 250$ for a service diagnostic, a family mechanic told me it’s my transmission good bad , can you help with advice since the dealership does not cover after 12k miles or 1 year , I can’t afford more Insurmace deductible
