When the box changes from 2nd to 3rd under load (uphill or accelerating hard) it seems to 'stick'; at about 3K revs and 'flatlines' ie wont keep accelerating (like i hit a rev limiter) but then after a second or two it carries on up the rev range to a third gear change.

Anyone  :jpshakehead:any ideas??

Have you tried to see if there are any fault codes (the 5 x ingnition on/off thing?)

Mouseman. What they're alluding to is this...... http://www.wjjeeps.com/faultcodes.htm Scroll down
to the bit that says "Retrieving codes."  Do what it says. Write down the codes it reports if there are
any. They are in the format Pxxxx, where xxxx is a number, e.g. P0120.
Scroll down that page to see what it means, and report back here for advice.
