Title: 2.5 td auto box
Post by: sadman43 on 18 September 2007, 05:41:40

Hi everyone, anyone help. when my auto box changes from second to third under moderate to heavy accelaration the gear box seems unable to select third and when it does the car jercks quite a bit as if the motor has misfired,  it feels like it can`t find third,  if i lift off a bit it changes up no prob, also if i go easy on the power it changes almost seemless throuh all gears, it`s better if i use sport mode, do I need a gear box oil change or is it more terminal.

I think the first stop would be an Transmission fluid change.

Also, have you had the software updated to the latest version. TB or MDTM have transformed rough running automatics into smooth running limousines with the upgrade.  :y
