Hi guys
I’ve got a question for you all can a weak battery cause my gearbox to play up at I’ve got a 2004 petrol v8 and I’ve noticed a slight judder sometimes but then I had to replace the battery and the judder seems to have gone

So my question is can a crap battery cause gearbox problems

Cheers Phil

I don’t believe so. The earlier ZF gearboxes are not known for their longevity in these heavy motors, though they are better than the GM box in the TD6.

Worth changing fluid?

A weak battery/low voltage can certainly cause issues with the ECUs e.g. TRANS. FAILSAFE PROG messages, etc. but I doubt it would cause a transmission judder. The most common cause of this with the 5HP24 is wear of the torque converter lock-up clutch friction plate. A fluid change, or friction modifiers added to the fluid, can produce a temporary improvement but ultimately the converter will require replacing/remanufacturing.

The most common condition for the judder (which can feel a bit like driving over a cattle grid) is up at slight incline at around 30mph, if it is the LUC at fault.

Thanks for that Phil
