S80 T6 1998 GM gearbox stuck on 3rd
Hello,
i just buy my first volvo s80 one month ago, its 1998.10 2.8 automatic with GM gearbox 200kw.
since i buy it i allready got message about the gearbox service it was sometimes stucking on the 3rd gear with S2 solenoid and RPM faults, ir was stucking on 3rd or skiping it at all. so i changed the gearbox from another T6 with same GM gearbox, and now i got incorrect gear ratio errors on 2,3,4 gears .i have tryed to change few gearbox computer but without luck, the owner of gearbox saying that it was working fine, and it really is. it shift very smoothly and without any hits. it only drops in safe mode when i am trying to keep stable speed from about 50-60km/h and get stuck in 3rd gear without any chance to switch in any other, i have to restart the car in order to get it working again. i believe this is the 3rd gearbox on this vehicle and canot slove the problem. i heard that the GM boxes is stronger then the aisin ones. i spend about 2k euros allready and still no luck!!! little bit details:
i connected vida dice and take it for a ride with RPM senosor graph on the screen one from engine and another signal from gearbox, so they are almost allways going at the same level and showing good information, since i get the error about the gearbox and stuck on 3rd gear the signal from gearbox RPM graph goes all the way up and stays on 6000rpm.if you need any other info from my diagnostics just ask. and please do not offer to change the gearbox becouse this is not the solution. any ideas?
vehicle cannot hold stable speed more then 50kmh when on any gear...puts in 3th and stuck on it.why!?all gears works perfect what is wrong with this car, nobody can find out...
