Re: 2004 XC70 P0733 Gear 3 incorrect ratio

Never had issue before with the A/T. If no previous flaring that would indicate the 3rd gear band was not slowing wearing out over time so maybe the problem can be corrected with the servo cover and new o-rings. Is 3rd gear completely gone now even at cold ATF temps too? There wasn't any transmissi...

Re: 2004 XC70 P0733 Gear 3 incorrect ratio

My wife was driving the 2004 XC70 for a couple of hours, then the 2-3 upshift flares. It's got no 3rd gear at all but it will bypass 3rd if I use the sport shift. I met up with her and drove it home. There's no flashing lights, NO red triangle, no CEL. No messages on message screen...nothing. I hoo...

Re: Cam Seals leaking at 120K, leave Oil Pump Seal alone?

Just my two cents worth. Not long ago I replaced the front crankshaft seal while replacing all the camshaft seals. At 20 years and 200K miles on my car the front crankshaft seal had no evidence of any leakage at all but I replaced anyway since I already had the pulley off. If you see no evidence of ...

Re: 2004 xc70 jerk shifting into reverse, with new valve body

Thanks, I'll check the pressure gauge when I get the tools. I saw that a few years back you also suggested backflushing from the pump section port accessible after taking off the valve body cover and a cover plate. Haven't found anyone try that yet. Wonder what you think about it now that you have ...

Re: 2004 xc70 jerk shifting into reverse, with new valve body

There's a good chance the sound is due to a mostly clogged and restrictive trans filter and this would explain the other problems you're having such as the harsh reverse. The gauge pressure readings will confirm if there's a problem with the pump pressure due to a restrictive filter. Assuming the fi...

Re: 2004 xc70 jerk shifting into reverse, with new valve body

If I have some time tomorrow I'll see if I can get solenoid current readings from my car. The B3 Low/Reverse brake doesn't have an external pressure tap, it's one of the two fluid paths between the valve body and case where the two o-ring type seals are needed. Solenoids S3 and S5 turn on for revers...

Re: 2004 xc70 jerk shifting into reverse, with new valve body

Thanks, those are very detailed and helpful. I guess I will first check the currents through the solenoids against the diagrams you referenced, which though is probably not the problem but should be easy to carry out using VIDA, so might as well check it out. Would be great if it's some external el...

Re: 2004 xc70 jerk shifting into reverse, with new valve body

If you decide to do the pressure check I'll provide photos of the gauge and the 1/4 inch pipe fittings needed. I recall I had to get a 90 deg elbow and a short extension to attach the hose to some of the pressure taps. The Sonnax tech info provides the expected pressure readings. It would be nice t...
