I have a small leak from the mechatronic unit on the gearbox on a V8 Discovery 3 (LR3)
I know technically you have to drop the pan to fix.
However, I am thinking of replacing with a metal pan system.
The main reason (silly as it may sound) is I hate taking exhaust bolts off - they have a tendency to shear in my delicate hands.
So I have a question:
Can the old pan be removed and a new metal one installed without taking the exhaust off?
and has anyone done it?
Please bear in mind its a V8 not TDV6.

In one word. Yes. The exhaust only needs to be removed if you're going to fit one of the original plastic sumps because you then have to lift the engine to get the one-piece sump/lifter pipe out.
Like you I didn't want to be removing seriously rusted clamp bolts with all the problems you then run into.
To get the old sump out go through all the procedures (leaving out the engine lifting parts) in the manual and take out the sump screws, a word of warning here; I had a problem with one screw (and wouldn't you know it it was the last one), the head sheared off so be careful.
Now you can manoeuvre the sump around so you can get a very tight access to the oil lifting tube with a hack saw and cut it off.
Now you can get at the leaking seal and fit the new filter and metal sump. It's a simple enough job, but it take a bit of manoeuvring of the pan to get it in place, but it's all very doable and no going near the exhaust.

Thanks.
I have two other questions;
Did you use gasket sealant on the pan/gasket?
....and do you think a cooking thermometer with a probe will be good enough to measure the gearbox oil temp for the refill?
Thanks for the help.

I did use a light smear of gasket sealer, mainly to hold it on the pan whilst fitting everything back, but if you only use a smear you'll do no harm.
Personally I used an infrared thermometer like this http://www.amazon.com/Arctic-Star-AR550-In...000MX5Y9C. Not sure how you'd get the cooking probe in and read it as well and remember the engine will running all the while that you're doing the final top-up.

Thanks for all the help.
Ordered an infra red thermometer, had one a few years ago must fight the addiction to measuring the temperature of everything that moves!
