venture transmission - 8/2/2006 1:31:40 PM    natureboy   Posts: 1 Joined: 8/2/2006 Status: offline At about 85,000 miles, my 2000 Venture's transmission has started shifting hard, making a whining noise. Took it to a shop Summer 2005 and they were unable to get the transmission to act up for them. They changed the trans fluid and filter. It still acts up sometimes, but not consistently enough that I would be sure it would still be doing it if I took it to the shop. Any suggestions? Post #: 1

It turned out to be the TPS (Trottle Possition Sensor). _____________________________ Regards, Craig Overland '98 Chevy Venture (in reply to natureboy) Post #: 2

Thanks! Chris (in reply to msra) Post #: 5

RE: venture transmission - 2/21/2008 5:03:52 PM    ktm521   Posts: 59 Joined: 2/14/2008 Status: offline The problem is the pressure control solenoid, when it gets hot it shorts out and commands full line pressure. This is the whining that you are hearing from the trans, its the pump. No cel will set but it will store a code of p1811 max adapt shift. I have done alot of these for this problem. You can diagnosis this yourself when its happening and the vehicle is shifting hard stop shut it off wait a minute restart and see if the whining is gone and it shifts normal again. If so thats the problem. Post #: 7

RE: venture transmission - 3/13/2008 4:30:16 PM    ktm521   Posts: 59 Joined: 2/14/2008 Status: offline  The fix for the problem is to replace the pressure control solenoid in the transmission. The symptoms are after driving awhile the soleniod shorts out and when this happens commands full line pressure to the trans. When this happens the driver will feel a really hard shift to every gear from take offs. If this is happening shut the vehicle off wait a couple of minutes then restart and see if it shifts normall if it does then thats the problem. _____________________________ GM Tech (in reply to wr450) Post #: 9
