Guest Guest_S80 owner_* Posted December 7, 2007 Report Share Posted December 7, 2007 Hello,This is my first time posting a question to a forum. I appologize in advance for any errors. Im mechanicaly savy, work for a large software company, and have an Electronic Engineering degree. I understand most mechanical turms as they relate to basic mechanics.I recently purchased a used 1999 volvo s80 t6 for use as a second car. The car drives very well and has a clean history confirmed by carfax report. I am frotunate enough to have all the service reciepts from the previous owners and the car was well maintained and met all its servcie dates.The current problem Im experiencing is "service tranmission urgent" message with an orange triangle. and when pulling the codes I see the following belowAutoTap Diagnostic - Version 3.10Date: 11/9/2007 10:06:13 AMHardware Serial: 0076395018Check Engine Light: ONTime Since Codes Cleared: ---Distance Since Codes Cleared: ---Drive Cycles Since Codes Cleared: ---Confirmed Diagnostic Trouble Codes: Code: Description: P1618 SBDS Interactive CodesPossible Diagnostic Trouble Codes: Code: Description: --------: EMISSION TEST STATUS :-------- Emission Status: <SELECT DATE>Vehicle Model Year: <SELECT>OBD Compliant: YesMisfire Monitoring: CompleteHeated Catalyst Monitoring: NotSupportedComprehensive Component Monitoring: CompleteCatalyst Monitoring: CompleteFuel System Monitoring: CompleteEvaporative System Monitoring: CompleteSecondary Air System Monitoring: NotSupportedEGR System Monitoring: NotSupportedOxygen Sensor Monitoring: CompleteOxygen Sensor Heater Monitoring: CompleteA/C System Refrigerant Monitoring: NotSupported --------: FREEZE FRAME DATA :-------- Generated by DTC code: P1618Fuel System Status Bank 1: OL-1 Calculated Engine Load: 0 %Engine Coolant Temperature: 221 °FShort Term Fuel Trim Bank 1: 0 %Long Term Fuel Trim Bank 1: -0.8 %Short Term Fuel Trim Bank 2: 0 %Long Term Fuel Trim Bank 2: -0.8 %Engine Speed: 0 RPMAfter resetting/clearing the codes the car drives perfect with no issues. The next day the error returns and I can feel the rough shifting again.thank you in advance for your time and advice Link to comment Share on other sites More sharing options...

Arbelac Posted December 7, 2007 Report Share Posted December 7, 2007 A quick search says some people have solved P1618 with a ABS module rebuild. Usually accompanied by other codes as well however. Link to comment Share on other sites More sharing options...
D s50r Posted December 7, 2007 Report Share Posted December 7, 2007 99.99999999 % of the time you will end up replacing the transmission that was the first year of the s80 and the t6 has the gm tranny in it in the past 5 weeks i have replaced 5 gm transmissions they are horrible im sorry no one told you not to buy that car Link to comment Share on other sites More sharing options...
MrWinkey Posted December 8, 2007 Report Share Posted December 8, 2007 I'm not gonna jump the gun and say you need a tranny and that they are horrible as the Gm cars that have them don't seem to have the same issues that the 80 series does? IMO half of the problem is in the programming and not the trans itself.It's only gonna do what it's told to do? Also that code you have is for a lost speed sensor input signal. Do you have an ABS light on or intermittently on as well? If so I would take a shot and say perhaps it may need an ABS module. $150/200 is a lot cheaper than a trans. However I'm not experiencing your symptoms so it's just a good guess. But I'm certainly not gonna condemn the trans for just a speed sensor code??? ;) Link to comment Share on other sites More sharing options...
