some time ago I bought a car. The first few days everything was fine yet suddenly there was a leak from the gearbox, between the silver and black cover (seal) under a fluid dipstick. The fault was repaired , the gearbox was filled with Dexron oil. I used the car for the following three weeks. One day I went shopping. Although there were no problems with transmition on the way to, on my return, the gearbox began to slip immediately after I started the car. I changed the oil (flush method) yet without any improvements. To make matters worse, no fault codes. When I start with RPM800-1200, everything is O.K., then it begins to slip, and then, from RPM3000 plus, it doesn`t slip. All the five gears are slipping.
Additionally, at the same time when the gearbox started to slip, the intercooler broke down and since then the radiator has been hissing (a whole)- can that cause a problem?
At VOLVO`s, they told me that neutral sensor 1 and neutral sensor 2 are broken (where are they????How to fix it???) b4 servo, perhaps software upgrading, any sensors or solenoids.
