92 Range Rover with cruise control + 4sp auto box - 110k miles.
After a recent service the following has developed - Occasionally seems like it's going to change gear but dosen't, seems like it slips for a second. This happens in all gears and normally at a constant speed, i.e. 40 mph in town, 75mph on Dual carriageway.
Also, it doesn't seem as responsive as it did, when reving the engine in neutral, there's a slight delay.
Possible advance/retard problem on vacume?
Have just changed leads - seem like consumables - 24K miles!
The gearbox oil/filter has not been changed in last 30K at least, probably never, just topped up.
Any idea's ???

Svc interval for ZF filter and fluid is 24k miles.
Good results can be had by using synthetic fluid on refilling.
Costs have been bandied about of around £125, which isn't bad if you don't have a pit or ramp to work from.
