Run the engine til hot, check the transmission fluid... If it is dark/dirty red and smells bad, it needs to be changed. If it hasnt been changed in your knowledge in the last 40,000 miles, change it anyway. If that doesnt fix it and the fluid was very smelly even after u changed it and ran it for an hour on the road, the trans may have to be rebuilt. There are some treatments you can add and many do work well, so go to autozone or Napa and check em out. I would recommend high mileage additives anyway if the mileage is high as you'll get more life out of the transmissio...hope that helps...if so rate me..

These Volvo 850 vehicles from the nineties have a poor reliability record and the automatic transmissions are prone to expensive problems.

I am afraid this vehicle, with over 200000 miles up, is well past its serviceable life and should be replaced soon. At this mileage you will experience many mechanical problems which will be costly to fix.

From what you have described the auto transmission is close to total failure and if you kept the car it would need to be replaced with a rebuilt transmission unit. This is very expensive and given the low market value of the vehicle, I am afraid it would cost more than the car is worth even if the car was in an operating condition.

Your only cost effective solution is to replace the car. Do not purchase a high mileage vehicle as you will be potentially buying a repair bill.

Preferably purchase a quality Japanese built used vehicle in good condition with low mileage and only after you have had a full mechanical check done before you pass any money to the vendor. You need to be satisfied with the overall condition of the car and be aware of any faults before purchase.
Finally, avoid European built used cars as they tend to become unreliable after only about 60000 miles and are typically quite expensive to repair and maintain.

The auto transmission doesn't shift from 3rd to 4th


It is possible that the computer is the culprit. Most cars with computer controlled trannys will keep in 3rd gear and only shift to overdrive when the engine has warmed up sufficiently. It could be a problem with this system. The best place to take it is your local AAMCO or Mr. Transmission, or the dealer. A regular garage will just be guessing in some cases unless the problem is revealed after running the engine codes.

'98 subaru wont shift from 1st unless rpms are high- morning only


When you first start driving it usually takes atleast 4 miles to warm the transmission to operating temperature. The temp of the motor may say it is warmed up, But, the trans fluid and differential fluid only begins to warm as you drive and the parts are actually working. THe computer has sensors that keep the trans from shifting to OD until the temp is up as not to add stress to the motor until warmed properly. Hope this helps and have a good day.

4l60e slips in 3rd and 4th


There are to many things that can cause this problem, best thing to is go get the ECM scanned for DTC codes at a transmission shop or Auto zone or Parts Source since they scan for free.
The ECM should have DTC code in it's memory on how the transmission is Performing and have the Transmission line tested for Fluid pressure.
Good luck and hope this helps. Oh and also ways check with more then on transmission shop if there tell you that you need a new Transmission,
It could be a simple as the transmission filter falling off causing the lost of transmission fluid pressure. Check the transmission fluid too.

Shifting problems


The transmission/computer is designed not to go into overdrive until it reaches a certain temp and I don't remember what the temp is. Mine does same thing and it has 250,000 miles on it. When you start your truck up do you start it and warm up in neutral? The transmission fluid won't flow unless it is. There is know way to force it to shift into overdrive until it warms to the set temp.

Hope this helps
