I have read that there is a re chip for the trans. But is there something the dealer can do to firm up the shift?

1999 e430 btw

 

swap in some updated solenoids. other than that you can get a eurocharged TCU tune for faster shifts.

 

eurocharged.com TCU tune

Improvements Include:
- Modification of Torque Management Settings
- Full "M" manual mode and "S" summer mode.
- Reduced Slippage
- Faster Shifting
- Raised RPM Limiter
- Gears hold when in manual mod
- Raised Trq Limiters

 

They emailed me and told me that the trans tune was not available for my car.

 

Curious about the solenoids. Any other info on this swap? Cost? Part numbers? Process? Outcome? Thanks,
