Thread: Gearbox rebuild

At 20,000km you can’t be using ZF fluid in it that’s for sure.

You'd pretty soon match the rebuild cost in replacement fluid.

Ive just picked up mine from A&B after full change out of transmission and T/C, they suggest a check over by them at 1000km an fluids and filters at wtee end 50,000 Km if that helps

yeah 50k is a reasonable marker, what it cost for the rebuild ?

The local small Gold Coast transmission place said they are rebuilding the transmissions on about 1 Discovery a week, and there were 2 in the shop when I stopped in....

Mine had 200,000km on the clock and has had 2 oil changes before that. He also recommended I change the transmission oli every 20,000km which seems quite frequent.

200000km seems ok for a rebuild if the fluid has never been changed. I hope they rebuilt or services the valve body too. Fluid changes every 60000km on these ZF boxes is reasonable. Using penrite bmv in these boxes causes no issues.

For reference, mines at 220000km and has had a valve body rebuild, steel pan upgrade and filter change, plus full fluid change at ~ 180000km and has been running penrite bmv since with no issues at all

I remember MR auto in Redcliffe(LR Indies) saying to me thay were also doing heaps of torque converters in the 6 Speed.

I wonder if these are predominantly tow tugs as I’ve never towed and don’t have any TC issues ‘yet’ (touch wood). Slight harsher change 2-1 / 1-2 but can’t determine if that’s more drivetrain related.

I seem in the minority of people not pulling a 2 to 3.5 tonne caravan around.

Yeah. I’d say so. Towing a house behind you will definitely wear them faster. Also seems the 6HP26 wear worse than the 6HP28 in the 3L
