Gearbox is a 01PG box.
The question was to see if anybody had any experience of trouble with this particular gearbox.
Thus far we have been unable to replicate the fault in the gearbox after an extensive test drive.
The complaint from the owner was that once it starts to judder, it is a regular event & feels as though the van is driving on rumble strips.
It doesn't drop into any kind of limphome mode & select & hold 3rd as it should if a fault is developing. But it does log the Torque Converter lock up clutch DTC.
If we can get it to judder / vibrate as described we will investigate the lock up clutch slip in MVB 007.
What I am asking is if anyone on here has experience of these T4 Autoboxes playing up & if so, does the fault description accurately present what is wrong - or is it a possible ECU / Valve Block issue preventing the lock up clutch from locking due to a control pressure or N91 Solenoid issue??
The fault the owner describes is symptomatic of a torque converter lock up clutch failing to lock - but we are looking for an experienced view point on this particular box before we go ahead & carry out a £1000 repair that may not resolve the fault.
Cheers,
Jon.
