wk2 loss of power

[Treebreakerbob]

Got stuck going to Oberon on the hill climb out of Abercrombie Gorge

21'6" 2.4 ton full caravan on the back, but have pulled that up there before without a problem

3.0 Motori diesel 5 speed auto

Selected 2nd gear at the bottom and just after the first hairpin the diesel lost power and we were losing speed, tried to knock it back to first, didn't go the first time but did the second time although we had lost more speed by then. Made no difference still wouldn't pull, came to a stop half way up only 50 mtrs from the hairpin, no engine malfunction or any warning lights came, gearbox temp 78 deg. Ok what to do, stuck on this steep hill wasn't fun, thought about low range but wasn't keen, motor didn't stall and was idling fine and as it was locked in 1st gear I thought the torque converter might let it rev up and we might make off the steep bit to the next wider hairpin. Gave it some throttle and away we went like nothing was wrong although I kept it in first and second gear and above 3,000 revs the rest of the way up

The car did feel like it had lack of power on hills the rest of the way to Oberon

Dropped of the caravan and went to the dealer in Bathurst and of course no fault codes and the vehicle behaved perfectly

On the way home we did experience some loss of power a couple of times when climbing but nothing like the first episode

Thoughts anyone?????

Any chance of bad fuel ?

I wouldn't have thought so as we had traveled 200 k's since filling up at a reputable servo

When I come to think about it the car has often had reduced power 10 min or so from starting out towing and I put it down to the dpf burning off

I did have the fuel filters changed at 40,000 which was not that long ago, they were genuine mopar parts I bought from moparamerica

Sounds like the beginnings of tranny failure. You'll probably find it happens in first - second when tranny is cold on a cold morning as well (if you get those up there).

That's something I thought as well'because when we started to slow down it felt like the tranny was locked up just like a manual gearbox and we were in to high a gear, but the car has pulled that van up there before in second

There is only 6 days left on my warranty

Long as the dealer noted your complaint in Bathurst there shouldn't be a problem ,now or in the future if it is the auto trans. Plus you have Australian Consumer protection as well. Maybe a problem regarding turbo boost. How many klms has the vehicle done. How old is the auto trans fluid, when towing the fluid should be changed around every 30000klms.Yours has the Mercedes 5 speed auto trans which is a pretty tough unit.
