Hi Everyone,
Although I love my 2018 S550 Mustang GT very much, I've had my fair share of issues during these few years with it. Things from premature speakers crackling and seat cooler failing to multiple 10r80 transmission issues and eventual total trans replacement. Luckily, these have all been covered under warranty, and each eventually resolved after months of working with the dealer each time. My warranty just expired this past March right after the trans was replaced, and although 90% of my issues were resolved, a couple still remain.
1. I hear a clunk when engaging drive, reverse and sometimes at beginning of acceleration or deceleration.
2. When at low throttle and RPM, the power delivery seems to "chatter" or "wobble". It doesn't feel consistent, solid or smooth for power delivery. Maybe this is what others have referred to as the car "lugging"? At higher RPM(3K+), the car pulls smooth, strong and solid, its a night and day difference.
Either way, I believe these issues may have to do with my drivetrain, specifically U-joint or Differential. After doing tons of reading online and watching videos, I want to believe that I've narrowed the clunk sound down to a U-joint issue, but I can't be sure since I also think I hear a clicking or ticking sound coming from the diff/U-joint area when driving with windows down near a wall/divider that reflects the sounds from my car back to me.
I took the tech who replaced my trans for a ride along so that he could hear the "clunk" and he told me it's normal. Nothing about this seems normal to me, but I decided to continue listening to see if it continues or gets worse. I feel it's been getting more prominent lately, so I'm taking the car back to the dealer to get it checked out before it gets worse or causes damage to the rest of my drivetrain.
Just some notes: I have a 52,000 mile 2018 10r80 PP1 401A car with Magneride suspension, on 19x10 square wheels. I have bought but not installed a tune yet, I wanted to fix any mechanical issues first. I am hoping to have a track day first week of July so I have a lot I want to get done in the next month.
This community has been amazing, and I would consider the people to be one of the best parts of owning a mustang. Please let me know your thoughts and what you think I should do. Thanks!
