P0730 OBD II Trouble Code

Unfortunately most transmission shops will say "needs a rebuild".
Sometimes you can get a low mileage transmission out of a wrecked car, but the install labor isn't cheap.

Now i dont know a lot about automatics especially modern ones with all this fancy electronics thats used nowdays but i think its a fault with the temperature sensor for the gearbox.But where its located and what it looks like i have no idea it could even be mounted inside the gearbox .Sorry not a very good answer from a mechanic but?? very few of our europeon cars come with auto transmission .Evan when i do know whats wrong i cannot buy the parts for the gearbox as only re-con boxes supplied by the dealer so best advice is to try a specialist in auto box repairs only .PS some of my best students when i used to teach mechanics many moons ago were the girls so no excuses like iam only a girl please

Code PO 30 on what? What is the machine, its manufacturer, its model, etc. ? Give some clue as to what you want me to do!

Taking it an having it diagnosed by a qualified repair shop would be your best bet .

have it scanned, probably has a code 1870 (transmission component slipping)
means torgue converter is slipping beyond specs, actual casue is valve body is wore out causing pressure problems

po 443= purge solenoid circuit
po 730= incorrect gear ratio, transmission problem
po 751= 1/2 solenoid problem
po 756= 2/3 solenoid problem
other 2 have no listing on alldata
you should seek professional help with these trans codes.
check ALL fuses first

Transmission is worn out or low on fluid

Start by checking the automatic transmission fluid level hot. You may want to take this to a local Volvo dealer to have the transmission serviced first.

Usually when the transmission slips, shifts rough, is noisy or has no drive in forward or reverse gears this indicates that the fluid pressure is low. When the transmission is serviced the oil is drained, the screen/filter is changed, the magnets cleaned and the pan cleaned as well. Dirt can clog the screen, which is a filter that is designed to trap particles that would otherwise damage the unit. The magnets are designed to trap metal shavings before they can contaminate the oil.

If this fails to correct the issue, the clutch packs could be worn out inside the transmission itself. These are the friction plates that actually perform shifting duties. The other possibility is that the torque converter or its pump is worn, resulting in low line pressure. Although replacement is possible, consider a rebuilt unit before repairing - the cost of installation of a rebuilt unit is usually about the same for repair of these types of problems. The result will be a vehicle that is both reliable and long lasting.
