D2 autobox shudder issue (maybe)

My son is having a bit of a issue with his D2 Td5 in the past week. I haven't been out in it yet but was wondering if anyone could offer some advice. All I can do is check propshafts really and change the gearbox oil.

"In the last couple of days, if accelerating hard (e.g. pulling out a lay-by onto a dual carriageway) I have noticed a shudder when the auto box is changing gear on my Td5.

The shudder only happens when accelerating hard from a stand still when it changes each gear (using the pulling out of a lay-by example). Normal driving is fine (normal Td5 driving!) and if you are driving along at 20mph upwards for example and then boot it hard, it will kick down and change gear as normal, no shudder and change gear fine all the way up to 70mph. Its just from a standing start it shudders through each gear change when pushing hard.

I have only noticed this in the last few days (30c outside temperature), not something I've noticed before. Could it be heat related (transmission oil temp)?

No warning lights etc or errors. If the answer is that the auto box is going to blow up soon then I'd rather not know. :lol1:

Any ideas?
In addition, what is the recommended interval for changing the auto box fluid?"

You should change the oil and filter as first move and go from there... according to the official maintainance schedule you have to renew the autobox oil and filter each 24K miles or 24 months... i'd change it more often if it was mine

to do it well drain and refill once go for a few miles drive as to make it change the gears several times then drain and refill again and change the filter too... this way you'll have about 80% refreshed oil, if you just drain and refill once it's less than 50% new

Yes will do that, mineral or synthetic atf?
I am thinking it maybe temp related as its only happened this past week, coinciding with the first hot weather this year. Took it out this evening and it was fine and the weather was a good 10⁰ cooler. Don't think the Foxwell will read gearbox temp.

Nothing will read gearbox temp as there's no sensor for that... the box would get hotter with worn oil and full filter anyway, i'd use Dexron III synthetic if i was you
