Thread: What would you do vis a vis ZF rebuild

IF I decide to hold on to the Disco its going to need the gearbox dropped to replace the rear main (my repairer has elected this option and personally I'm happier with this than pulling the engine.)

So basically would you rebuild the gearbox if it was out? Its got 230k on it, shifts perfectly, no hang in 1st, but still 230k is 230k.

Also I'm not too sure of the stall speed on the Tdi automatic variant, it seems very high, does anyone know? I've gotten used to a 4L60E and it feels like 1500 rpm!! Is it possible to have a lower stall converter during the rebuild?


My reasoning is don't rebuild it as you may well get another 70,000k out of it, but on the contrary whilst it's out it would save on doubled up labour costs to remove again later.

It is way easier to pull the engine regardless of if you have a hoist.

It's not the sort of box that you can just hoist up on your shoulder and trans Jacks are most of the time more suited to car trans than heavy 4wd/truck trans.

Pulling a Tdi out isnt that hard, nowhere near as much crap on it as there is on a V8 and a lot more room around it to work and all you need is either a Gantry (the easiest way) or a high lift engine crane.

Im pretty sure after removing the radiator etc you could probably just move the engine forward and do it but I prefer in cases like that to pull it out, clean it up and do a few of the fiddly jobs while its out and it gives you a chance to check out all the odds and sods in the engine bay that you normally dont get a good look at with the donk in place.

Leave the Trans, do as Dave said and it will last another 250000k, mines done 300000k of thrashing, previous owners (2 of) towed vans around Oz and then my 4wding for the last 120000k has left it with a buggered sprag but you can drive around that easy enough as it doesnt do it all the time.

It's starting to get a couple of leaks now so it looks like I will get it rebuilt in the next year or so but Im in no hurry.

By the way, dont rely on dealer times, they are allways nowhere near accurate and are only there to put pressure on their techs to pump out more work.
