lawrence Posted November 7, 2010 Share Posted November 7, 2010 I've got a 300tdi auto which has started a real problem of not changing gear. this only happens every so oftern and only at the start of the trip, I have been able to make it change by pressing the gas pedal all the way to the ground. once it changes once it will be fine for the rest of the trip with no problems at all. This doesn't happen all the time, but today I hav ebeen out to the car a few times it won't change down at all. Only started a few weeks ago. Is there a setting in the engine for the auto change that could have altered or do I need a whole new gearbox. Quote Link to comment Share on other sites More sharing options...
Dave W Posted November 7, 2010 Share Posted November 7, 2010 It's unusual for it not to change down, the more common problem is that of it sticking in 1st when cold. The kick down cable is the first thing to check, make sure it's correctly adjusted and/or attached. Quote Link to comment Share on other sites More sharing options...

Dave W Posted November 7, 2010 Share Posted November 7, 2010 If it's stuck in first it's not the kickdown cable, it's most likely a governor problem. Generally this problem only occurs when the gearbox is cold and, once it warms up and starts shifting, it will shift quite normally after that point. A brief explanation here... http://www.ashcroft-transmissions.co.uk/index.php?act=viewProd&productId=221 You can replace the governor and/or it's O rings (can be done in situ if you remove the transfer box) but if the problem is caused by bits of brake bands floating around it may well be an early indication that you're going to need to rebuild the gearbox at some point soon. Every gearbox I've ever had do this always ended up losing the A clutch (no forward drive at all but reverse is fine) so unless there's a split o ring or something like that replacing the governor is unlikely to be a long term fix.

Dave W Posted November 7, 2010 Share Posted November 7, 2010 £675 currently... http://www.ashcroft-transmissions.co.uk/index.php?act=viewProd&productId=51 Not sure if Dave gives a forum discount on that, you'll have to negotiate or I'm sure he'll be along shortly as he's a regular on this forum Quote Link to comment Share on other sites More sharing options...
lawrence Posted November 7, 2010 Author Share Posted November 7, 2010 I'll have to hope Dave sees this thread and leaves a helpful comment then. Now just need a gararge to remove the old one. Quote Link to comment Share on other sites More sharing options...
Range Rover Blues Posted November 8, 2010 Share Posted November 8, 2010 Not as bad a job as I expected. Once I knew where all the bolts were I found it easier to remove the transfer box first. I do have access to 3 big trolley jacks though. When I do mine (again) I'd rather spend the extra money on the stage 2 upgrade and fit it myself.

lawrence Posted November 8, 2010 Author Share Posted November 8, 2010 fitting a new gearbox I think will be well outside of my knowledge base, So I am going to have to pay someone to fit one, if it comes to that. At the moment I am hoping that an fluid and filter change fix the problem. Quote Link to comment Share on other sites More sharing options...
lawrence Posted November 13, 2010 Author Share Posted November 13, 2010 Well the fluid and filter change did nothing. So where is the best place to bet a new gearbox from. Quote Link to comment Share on other sites More sharing options...

tort172 Posted November 14, 2010 Share Posted November 14, 2010 disconnect your kick down cable first and make sure it is moving freely in and out, had this on a friends disco would not change up as cable was seized in kick down position new cable fixed it Quote Link to comment Share on other sites More sharing options...
