Good day
I Have started removing the 21 bolts from the gear box S type 2.7 D
I brought a impact drill and new bits to do the job with ease.
After removing some with no problem I found that 7 have just rounded of the Fred
I cut a line in to one with a grinder and tried to do it again with a straight bit and the bit broke off. pictures below.
Please help what is the best way to remove the studs size 27 star ?

No pictures came out?? And I assume you mean the oil pan on the transmission?
But it's very common and exactly why Jaguar came out with the replacement T40 bolts.
Several ways to get them out.
1. Grind a slot in the bolt heads with a Dremel tool and use an impact driver with a flat bit.
2. The heads stick out a bit from the plastic pan and you can grab them with a pair of vise grips and break them free. Remember the plastic pan will be replaced because the filter is built into it so don't worry about damage to the plastic.
You did use a T27 bit? I see you did so someone may have rounded them off before you tried. Many people have rounded them off because T27 is a bit odd and everyone has the T25 socket. Poor idea in my mind to use oddball hardware. Just not needed.

I change the sleve as well the gear box I brought as a kit.
yes the job was not that difficult just make time to remove the bolts.
The sleve came out with just a turn putting the new one back was a bit of a task.
I sold the S type for the XJ 350 which I do love, around 12 months ago.
I am getting the gear box fault sign again but only when i go up very steep hills.
I went to get the gear boxed reprogram at Jaguar in south of france I was told the car would not take on board the new program and I would need a new gear box this is what i was told with the S type 2.7 at jaguar Monaco.
They still charge me 190 euros which was for nothing I felt cheated.
