Question ~ XJ40 Power Steering Fluid
According to the Haynes manual, the '88, '89, '93 and '94 models use ATF in the power steering systems.
The '90, '91 and '92 models with the steering system combined with the self leveling rear suspension systems use some sort of liquid Kryptonite that can only be purchased on a dark street corner from a guy named Vinny, and paid for with unmarked bills .... and lots of 'em!
My question is:
If the self leveling suspension has been converted to standard suspension parts, is it still necessary to run the Castrol hydraulic fluid, or is it OK to use ATF.
All the sources I've viewed go into detail about converting the suspension back to standard parts, but no one mentions the fluid requirements after the conversion.
Thanks in advance for your help and/or thoughts.

Yes the fluid can be drained and replaced with DEXRON. I have a 1992 XJ6 and I removed the SLS and front pump/solenoid block from my car. I capped off the small return port on my reservoir and filled it with DEXRON. No problems since 1998.

Thanks Bob, that's what I was hoping to hear.
I assumed that the hydraulic fluid was primarily for the suspension, but wasn't sure if the braking system (seals or whatever) might still call for the same fluid.
I appreciate the info.

This is what I was hoping to find. I am changing the steering rack on a 90 XJ6 and it has red ATF in it when we bought it. Dang mineral oil is hard to find on short notice. I was told by Jag dealer that the way to tell if I have SLS is if the reservoir is square. If it is rectangular, it is not SLS. Does anyone agree?
