Mercon SP OR Liquid Gold? XJR
Heeeeeyy everybody, looking to do a transmission flush. Almost at 90k miles, I presume that it is the original fluid. Very very subtle lurk from 1st to 2nd, seems to only do it when babying the accelerator so it could be that.. If anything chalk it up to preventative maintenance.
I have read several gentlemen on this forum say " Mercon SP is the same fluid as LiquidGold6. "
Local tranny shop quoted 189$ for a 12qt flush of mystery oil, and that seems scary.
Should I replace the pan/filter while I am at it?? Wait till 150k?
So, Mercon SP or not? Save some money for sure

Do the pan/filter and most importantly the sleeve (seal for the electrical connector) at the same time.
I did mine at 95'000mi, and used ZF Lifeguard 6
$100 difference to use the genuine fluid, not a dealbreaker for me...
EDIT
Just FYI, here are the p/n for the various OEM fluids to suit the ZF 6HP transmission in 1L bottles
Jaguar #C2C8432
Land Rover #TYK500050
BMW #83220142516
ZF #S671090255
You will find the BMW stuff cheaper online if you search, like $23 a litre, also search by the ZF part number.

Thank you for the response Cambo!
I wonder if this is for one bottle, first google result for the ZF #:

I vote for the Life Guard 6, as that's what I used. Definitely change pan/filter and sleeve. I first tried Mobil 1 because I read others had used it, and I added some Lucas stopslip. Not a good decision, later to find that I had changed the viscosity too much such that I got the RPM surge. Did a complete flush and replaced with all LG6, problem solved. It's such a key element of the trans and the whole car, that I don't think it's worth $100 to skimp on the original in this case.

Well I must say, 436 votes to zero, pretty definitive victory for ZF.

Check this thread out. It is in the wrong forum but that is what I did to my car 11,000 miles ago.
Pan with filter replaced, 6qts of ZF oil, bolts upgraded + sleeve replaced
Tranny Fluid replacement

That is an awesome DIY thread! Fantastic job. I had the flush done today, got the sleeve and 12QTs from CTSC for like 250$ shipped, I forget exactly. Scored the pan on Ebay for around 70$, seems perfect, German made.
Unfortunately though the problem seems to have gotten a little worse (harder 1st-2nd). I am sending the fluid off to be tested on monday.
Old fluid
After Flush
Comparison Shot
Idears???

Well, had a pretty well reviewed indy do my TCM adaptation delete and software updates today, could not make it up to Jag today because we were expecting a few snowflakes to fall on the ground, and in North Carolina that means that the apocalypse is near and everything must close before cars start flying off the road like in a godzilla movie.
They had two S types in the shop so that made me feel a little better about visiting a shop I have never been too. Import Performance in Wilmington NC, foumd it using Jagshops.com.
All went good, no problems. I was behind on the software as we figured, I am behind on the other updates for ECU and such, we will leave that for another day.
156$ for the flash and update, and a AC system check which I failed... God Dam heater core.
Feller told me the car will shift like a drunken red head for a while. On the 60 odd mile drive home I noted 1-2nd felt slightly better than it did before I did the flush, and the other gear shifts are grabbed slightly harder. Keeping my fingers crossed.
I like to take off with the verosity of a 93 year old in typical driving conditions, so I wonder how much of all this 1st to 2nd wonkeyness is just me

Ahhhuhm, my reading comprehension skills failed me when I read this the first time.
Should I have asked them to complete my drive cycle for me?!?! Suddenly confused.
