Could you supply the model of XJS you have e.g. 1996 XJS 4.0 Celebration or 1989 XJ-S V12 5.3 HE? This would help with confirming the transmission model you have.
Wow, that's a rare beast indeed, seeing as how the facelifts started in '91 and the 4.0 wasn't fitted to pre facelifts...Its a 1992, 4.0.. Pre-facelift
Sorry for my ignorance, but how do I do this. I dont know what the gear ox is but the selector only shows 2,4,and DHi,
I *think* that your transmission will be a GM 4-speed unit. As such, it should support a fault code reader? Have you checked to see what fault codes have been logged?
I assume its a pre-face lift. It has chrome bumper with black plastic splitter underneath. (Cant get a photo to upload)Wow, that's a rare beast indeed, seeing as how the facelifts started in '91 and the 4.0 wasn't fitted to pre facelifts...
Assuming it's got the 4 speed ZF 4HP24 box, then any of the wonderful bits of electrickery could be a cause. The throttle position sensor can even come into play.
The bumper didn't change until 2 years into the facelift production. The door glass is a better indication. If it's frameless, it's a facelift. The rear glass is also different, no plastic.It looks like the older models. (It does not have the newer looking large bumpers)
Where do I find the gear box ecu on the car and is it possible to check it.
Stupid question, but is there such a thing as a Heynes manual for the XJS. I cant seem to find one anywhere.
