Help! Al4 Gearbox Problems

[legacylady]

Hi Can anybody help with Fault codes that my Lexia has given me.

 

B008  ( Remote Control Wake-up wire RCD)

 

0006 ? fault not listed

 

C404 (incorrect Gearbox Vaule Recieved)

 

Car started giving gear fault, bumps into limp mode, sometimes over revs to. does this on EVERY jorney now. quick fix is to turn off and turn on again but now over revs everytime.

 

had the body valve out and cleaned solnoids and cleaned body valve and put fresh oil in. but still no joy. invested in the lexia computer and got them codes. not sure what to do next!! HELP!!

Cleaning the valve Body (making sure you do NOT scratch the Valve Body and tighten the bolts to the right torque) and changing the oil may help... you can also try over filling by 250-500 ml of oil to see if it helps..

 

If all that does not help, replacement of the 2 Borg Warner solenoids is next point of action, it solves the problem most of the time (before stripping or replacing the whole box)

p.s. Some people had problems due to blocked Oil Filter and/or damaged Oil Pump .. This requires the removal of the Gear Box..
