Robrayc Posted May 10, 2020 Share Posted May 10, 2020 My 2004 TD5 Disco auto gearbox won't go into fourth gear no matter how I try to select it. What could be the cause? Rob 😊 Quote Link to comment Share on other sites More sharing options...
Escape Posted May 10, 2020 Share Posted May 10, 2020 You can't really select 4th with the ZF in the D2, you can only allow the ECU to shift up to 4th if it thinks that is the correct gear. Are you sure you're not in 4th? Revs too high could also mean the lock-up isn't engaging. Best test would be to take the car up to speed, let it shift through the gears in D and when it should be in 4th move the lever to 3rd and watch the revs. You should first see a notable increase in revs and then a small drop, as the lock-up engages in 3rd. Once you can confirm the problem, I'd start by looking at the oil in the autobox. Maybe it would benefit from an oil and filter change. Filip 1 Quote Link to comment Share on other sites More sharing options...

Kaj Posted November 15, 2020 Share Posted November 15, 2020 I have 2006 Range Rover 4.2 supercharged when I have it in drive the transmission will not shift from 3rd to 4th and then I get limited gears fault. If I shift it manually it shifts fine any ideas? Quote Link to comment Share on other sites More sharing options...
