850 TDI Station Wagon Automatic weak points?

I am amazed that the automatic transmission has made it to 140,000 miles. They often fail catastrophically around 50Kmiles and every 50Kmiles thereafter. Some don't have this problem but, if you search back on this newsgroup, you'll find dozens that did, many under warranty.

You should also look out for all the usual 850 problems as well: failed air pump, climate control (if installed), anti-lock brake control module, and AC compressor clutch and evaporator. For little things, expect to replace the shifter microswitch, the rear hatch supports, the headlight switch, and the power seat cables.

Both of my 850s had electrical problems (drained battery overnight in the winter) which, in both cars, turned out to be the glovebox door not depressing the switch once it got a little old and loose.

By the way, my wife has a new Honda Fit on order. If anyone in the Boston area wants to buy her '96 850 GLT wagon (110 kMiles) for $2500, drop me an Email. Then we will have no Volvos (after 30 years), and I can spend my weekends with my kids, instead of fixing the cars.

I thought they fixed that in '95 by increasing some tolerances.

Cambelt belt and diesel pump belt need to be changed latest at 240.000 km, you must be ready to pay EUR 1000,- for a such a swap including the water pump, which is a good idea to change as well. The engine is similar to Audi A6 2.5 TDI and is a great engine - long lasting. The diesel pump must be adjusted from time to time to make sure that engine starts well and to prevent too much diesel smoke. The automatic gearbox should shift completely smoothless including when the car is standing and gear lever is changed from D to R.

Can you please tell me how much money should I expect from a Volvo shop or non-Volvo shop to charge for adjusting the diesel pump, and how long (in hrs, minutes?) is the job?

THNX a lot.

Friends of mine happen to have an Audi with the same engine. The belt has to be changed after a certain amount of km OR TIME, which is important. Their belt broke and they had a 6000 ? damage to the engine. Also with my old 745 Volkswagen LT Diesel engine my mechanic changed the waterpump at 300.000 km together with the two belts.

You probably mean smoothly :-)

I get the impression after reading the on the net, that the automatic gear box is a weak point in this car. If that is really the case, I would not even think to buy it. There are very few automatic gear boxes for such a car at the vehicle-butchers' yards and maybe very expensive. My 1989 745 TD manual gearbox with overdrive works fine at 370.000 km. The only thing I did between 245.000 km and now was in spring when I changed the overdrive electric relay.

The gearbox'es in 850 TDI and V70 TDI Classic should be pretty ok. The new shape V70 D5 with the original aut. trans. you should stay away from. Tranny only last shortly because they are too weak build. In general high speed autobahn drive is not the best for an aut. tranny - this is the reason to check if the oil pressure in the tranny still is ok - e.q. smoothly shifting. You should expect about tkm. 300 with optimal performance of this tranny.

The problem with broken belts in Volvo 850 TDI was to due the belt tensioner causing the belt to vibrate too much - a service procedure fix is made for this problem at volvo.

Forgot to add: aut. tranny problems only on early releases of the new shape V70 D5.

I have had 10 Volvos with AT's and only two AT's failed. The '87 240 AT needed work around 100K miles, but a routine overhaul fixed it. The '93

850 AT failed at 145,000. It needed a factory rebuilt unit. I drove my 240's and earlier models 120,000 miles and drive my 850's 180,000 miles. I don't see any sign of AT's often failing around 50k miles.

50k is abit mean, but the Aisan Warner AT in the 850's and V70 classics can and do fail at around the 120k mark *unless* they are given regualr fluid changes. Volvo decided not to specify any fluid change in the maintanance schedule and this is the root of the problem

Early 92-95 850 AT's are much more prone to failure than later units.

Do you have any documentation or are you just winging it. If you check, I think you will find that those that fail have a failure centered somewhere around 120,000 miles, but many of those that are properly maintained with dealer service don't fail during the life of the car. I know 80% of mine didn't fail during the life of the car.

And my '93 850 transmission (the worst year for Volvo transmissions) lasted 145,000 miles, so I would say they are pretty good. Not many clutches last that long.

If you speak about the 800 / 70 series manual gearbox clutches, there are

*plenty* of them about with upwards of 150k miles on the clock still on the original clutch (T5's slightly less so)

Tim..

It would be pretty remarkable if every single one of the '93 automatics had failed early. Be grateful you had a good one, but don't take your experience to be the last word on the subject. I'm pretty sure I saw a Yugo on the road this year...
