tranny swap
My 82 xj6 has a pretty bad fluid leak, and the 3 speed isn't all that great to begin with. So the question is what transmissions can I swap in there? A 700r4 would be really nice. Would like to stay automatic. Would I have to make an adapter plate? Want to keep the original motor in this one. It's my only ride I haven't done a motor swap too

Setting $'s aside, if the BW has to come out to reseal it, seems the time to install the 700r using Johns kit. His term "quarter breed". OD is a neat thing. some say the 2.88 Jag ratio and the .70 Od is more than the 4.2 can handle. That includes John. Others say not so much. On the flats, it would do just fine, I think. On hills, so it drops down. Not all that bad. And, if the seals on the BW are leaky, how are the bands and clutch disks??? Preemptive fix or just swap it.
My 83 with 2.88 and OD auto fare quite well. Oh, I forgot, my lump pulls another 100 HP or so and a ton more torque!!
Shipwright. If one swaps in a 700, why not the rest....

I'm a jag purist I guess. I think Some cars are meant to stay original. And the straight 6 4.2 xk engine puts out ample power. It's not my racecar, its my cruiser and I drive it like one. With 115xxx miles on the engine, there is nothing wrong with it. Sure if it ever blows I would do an lsx swap, but hopefully that won't be for awhile

82:
I sure respect that. And, that isn't high mileage. Only horrendous thought is that it might be head gasket time. And, although not easy, certainly doable.
So, in that case, I'd not only reseal it, but install install a soft kit, ie new bands and haps clutch disk. Good for at least another 100k. The BW's are old tech, but very tough.
My car isn't a racer. Just great mileage and eats the miles while loafing in OD. Taking the 100 pound load off my front springs restored factory ride height. Although, I did like the slight forward rake!!
But, I do espouse "to each his own".
Well, to a point, I have issues when some butcher decent cars for whatever reason.
In my case it was either.... or Jaguar heaven. Odd, that the yard is not far from where my car suffered it's calamity???
I did like it a lot as a 4.2!!

I have thought about a tranny swap to 4 speed auto, with the old three speed she revs a 3 grand and 110kph I would have thought that extra gear would reduce the revs and inprove fuel use. I am wrong? Have to say thou Lady J will be keep orginal. Maybe the next project might be a modified.
