Edit: I was in college and likely hungry, lacking sleep and Mommy and daddy were out on this one. Continued driving the car until 2014 with a new upper engine mount and a lower transmission mount. The AWD was completely fine.

I could rip my hair out.I just spent $3,700 on repairing the transmission in my '99 XC after a bout with the flashing up arrow. That was back in November of last year. And for the last couple days, I've noticed some really disturbing behavior. As soon as I let off the gas pedal, my RPM's drop suddenly to idle speed (about 800 RPM and as soon as I press the gas pedal, it responds just like it should. I've also noticed a harsh jolt that happens sporadically. Typically, it seems like the RPM's should gradually lower, When I upshift, the RPM's hardly lower at all, they dip about 500 then go to normal rotational speed around 2000 RPM (at 65 mph) Transmission fluid seems unchanged since this started happening. Nothing burnt, but the fluid hasn't been bright red for a while now.Any ideas?? It's very scary. I love this Volvo, but if I have to rebuild the transmission again on this car in less than one year, I am going to be so done. Well, in spirit, I will be. has just started happening little over one week ago. Could it be the transmission mount? Should I change the transmission fluid?

Re: HELP: V70XC Harsh shifts, increased vibrations, preformance normal then immed ... (jtridenour)

Either they did a poor job of rebuilding it,
your PNP switch is shot
and/or you have the ETM problem
any and/or all of the above

(The flashing arrow can be just the PNP switch, was that ruled out before you spent money to rebuild the trans)?

Motor mounts cannot cause this and DO NOT DRIVE with the flashing arrow.. (Read this and absorb this, this is not an option or you WILL screw it up again)

"ROW" the shifter back and forth about 20 times, engine on, brake ON. (foot on brake)
If the switch has dirty contacts this usually clears it up for a while.
If that does work you will still need to replace that switch soon but that may be your only problem) and will cost you a lot less money, (about $300 or so installed)

Thanks, JRL. I'm almost certain it's not the PNP switch as I've not seen the up arrow since the trans gave out. I crawled under the car and saw a very light bit of transmission fluid around the area of the transmission. I had to wipe around with a white paper towel in order to see it. I've not seen this before. While I was under the car (with it running) I could hear a very rhythmic whine which made my stomach drop through my wallet. I've been checking the transmission fluid each time I drive -- it is still reddish but it isn't bright (and hasn't been since I got the car back). I'm at school now, should I try to put a bottle of Lucas Stop-Slip before I head home? With the added knowledge of the whine (almost like a belt noise), should I attempt a drain/change?

Warranty?
Most reputable shops have at least a 1 year 12K warranty on tranny work.
If not, try small claims court if they won't do good by you on their (shoddy) work.
