I've been searching these forums for a problem I encountered the other day and I think this thread may be relevant.
2001 V70 2.3 T5 Auto w/ Geartronic
126,000 miles w/ a transmission that was replaced @ about 80k.
Transmission Service Required light on w/ P0740 Torque Converter Clutch Circuit/Open
P1618 (unknown w/ generic my scanner)
I hadn't put much thought into a whining sound other than the weather changing and the engine being colder in the morning but I noticed a little bit of a whine when my wife drove away a couple weeks back. This was described earlier in the thread as the transmission possibly be starved of fluid. Neither of us other than the whine had noticed anything else and from my memory the whining did go away after everything was warmed up a couple minutes down the road.
Fast forward to last week I was driving on the freeway @ 70mph (and had recently engaged cruise control). Shortly after that the Trans Service Required light and check engine light illuminated simultaneously. The gear indicator only had a "-" rather than "D", "R", or "P". There were no noticeable changes in the remaining 20 minutes of freeway driving. I exited the freeway and came to a complete stop, and accelerated without any noticeable change. After the next stop, I accelerated and engine RPM's raised abnormally higher and it seemed the transmission was slipping. Each stop after that progressively got worse until I made it to the driveway at home miraculously and had to push it into my parking spot.
There were no bad smells, sounds, or anything else that would have hinted at a problem so I'm absolutely lost.
Today I started it and was able to pull forward in drive after cycling through gears but in reverse the engine simply revs and the gear never engages.
Here's a little video clip...
Thanks in advance!
