Should be a New Venture 3550 like mine. Does it sound like a diesel when in
neutral with the motor running? If so, it's the NV3550.

Hi Nick,
    That information was wrong, as Peter pointed out. Your build order
is sometimes left under the seat stuck in the springs. Or request it via
writing Customer Assistance, from:

Thanks for the comments, I have emailed DaimlerChrysler in the states
on the link posted earlier with my VIN details to see whay they say, I
am not sure why it would be a 99 car(but anything is possible) as the
Jeep sticker inside the door gives a manufactured date of 2002 I can't
remember the month and its chucking it down outside so I am not going
to venture outside to look (not the true Jeep spirit I know :-)   ).
I will wait and see what Jeep America come back with as it is my local
dealer who's given me the information about it being an Aisin box.

Cheers
Nick

Where was your Jeep's assembly location? I don't know if TJ's for the UK
market are assembled in North America or not. If not, it's possible you have
the Aisin, tho that's just an assumption on my part.

DaimlerChrysler have come back with the full listing and it is
definetly an NV3550 in the car, thanks for all the responses.  So I am
off to buy some Redline MTL to stick in it.

Nick
