Hyundai Elantra transmission problem
This is a follow up to my other video http://youtu.be/oXk2gtHmuiY Pulled into my garage and car is stuck in Drive. No gear is registered in the gauges. I can shift between Drive and Neutral but there's a loud pop each time. The shifter is physically locked out of going into Reverse or Park.

Bad wrist pin is causing piston slap (dull knock under load)
2005 Hyundai Sonata with G4JS 2,4 I4 engine developed a dull knock when cold under load. Bad wrist pin is the main suspect. The engine knocks loudly under load after cold start, especially if oil level is low (the lower the oil level, the louder the knock). The sound is similar to piston slap, i.e. dull, tapping knock, like a piece of wood is hitting metal in the 1,200-2,000 rpm range. Also the colder the weather outside, the louder the knock is. The noise is somewhat quieter if higher octane gas is used. The engine doesn't knock at idle, however it produces a diesel like clatter when idling at operating temperature. The knock fades away when the engine is hot, but a little bit of it still remains. Recently did a compression test with the following results: 13.0 - 12.5 - 12.5 - 12.5 kg/cm2 or 180 - 175 -175 -175 psi. Engine spec according to manual is 12.2 kg/cm2 or 170 psi. The knock doesn't go away immediately after the engine reaches operating temperature, but after driving maybe 20-40 minutes. Even if the engine warmed up until op temp before drving, the engine still produces very audible knock. However, if I warm it up for about 15 minutes (reaching the op temp), and the let it sit for 20-40 minutes, it doesn't knock that loudly when driving. At that time, temperature gauge might drop even below the first mark, indicating cold engine, but it stops knocking loudly.
2005 Mustang GT. This noise comes from the rear end and is only heard on deceleration or letting off the gas. When giving gas the noise goes away completely. The noise occurs about once per wheel revolution. The problem that caused the noise happened when shifting into 4th gear hard under strong acceleration. It sounded like a shotgun went off in the rear end. There has been no drive-ability issues related to the noise that I can tell. It's just really annoying.
