I wonder if the software can be updated with the GAP IID Tool? I will have to run a diagnostic this weekend and see what software updates may be available in the transmission area.

Hi guys my car is experiencing the same issue hard thud when I put my foot down on downshift I have phoned my local steeler who have said there is no bulletin out for this issue and they have never heard of it before. Have you any more info on this issue also what was the cost for the software update form the steelers.

Don't it make you want to cry when they say' they have never heard of it before'!!

Highly likely engine mounts. Have someone rev the engine while you watch the motor. It may rise several inches, likely from the left side.

I made a post some time ago of how to replace yourself with a friend. Fixed my acceleration/ downshift clunk immediately. Dan. 🇨🇦 2013 L405 5.0 SCV8

Would loose engine mounts cause this issue as there is no vibration etc and I only experience this hard thud clunk which feels like it coming from under the floor when I put my foot down and then the car obviously drops gears.

I did the update after a transmission and transfer case fluid change. I thought that cured it. It fixed the TC noises, after a second flush, but the hard shift/clunk was the engine mounts.
