Hi there! Wondering if anyone has some advise/help
Got problems with my td5 auto.
When the vehicle is cold I put it into drive and seems to start of in 2nd gear as I pull away it struggles and easily gets up to speed to 30mph without changing gear.
Then after driving for 2 mins I come to a stop and it then goes into first gear and won’t shift out of first for a good 2 mins or longer holding the revs up high . Once It has warmed up a Little it seems to change gears okay but they are still delayed and don’t seem smooth and hesitant in upshifting.
I have done two gearbox oil changes with filter and new oil and topped it up with the vehicle running and in neutral.
Oil was black and burnt smell
I have done the stall test and seems to rev to about 2400rpm
No faults codes on gearbox or engine that are relevant
I have also tried in low and with manual mode and selects first fine but won’t select second gear but 3rd and 4th gear is fine .
Any help would be much appreciated many thanks

Try a few oil changes or some transmission additive, Ashcroft’s sell some for autos, not ideal but if box is knackered anyway nothing to loose, worth a try. Iv changed my oil a few times, was dark brown but not black, Diesel engine oil black kind of thing but changes beautifully now.
