| Gearbox reluctant to engage 6th gear when cold |
|
Morning
As described really - wondering if this is something anyone else has encountered or knows about.
Setting off from a cold start, the gearbox won't go into 6th gear on its own around 70mph. It revs in 5th gear instead at c. 2250rpm or something similar.
If I use command shift it will go up. Or, if I accelerate past 70 to 75 - 80mph, then ease off the throttle, it will also go in on its own.
I'm happy to view this as just a quirk of a 200k+ miles gearbox, but any other info appreciated 
Chris

supposed to work that way its to let the engine/trans get to normal temp quicker you'll prob also notice that when its cold the trans free wheels when you come off the throttle for the first mile or so please excuse any grammer/punctuation mistakes,i'm thick,thankyou

As mentioned, this is normal function but one thing to add. I have had my D3 for a year now and this functionality got much worse....seemed to hold onto 5th for a long while...c.10 miles even after things should be quite warm. I found it too much and really annoying.
Turned out that my oil temp sensor was faulty and was intermittently giving false readings (this also caused other temp gauge issues). After I replaced that sensor, the gearbox behaved much better....no doubt my engine fuelling was a lot healthier too!
Point being, if it gets worse or you feel this happens more than what should be the standard design then that might be a place to look - common fault apparently and was only about £20 and an easy fix.

Ah right ok... is it an engine oil temp sensor or gearbox oil temp sensor?
