First thread here, I would like some advice from you folks.
Recently, I’ve been experiencing a weird whine/hum coming near the engine bay — it is noticeable upon gradual acceleration.
In addition, I’ve been experiencing light jerking towards the higher speeds — during both upshifts and downshifts going 50+ mph. Most notably, the car jerks violently from 6th to 5th gear every single time when I manually downshift. Same occurs when you put the car from reverse to drive.
Any ideas on what I could be dealing with? I believe I need new motor/transmission mounts. In terms of the whine/hum it may be deriving from the torque converter; ZL1 is currently at the dealer and I expect to hear back from them by Thursday.
