My 99 transmission Service Urgent light came on. Took it to the dealer. Found a fuse blown he says and reset the light. Transmission Service Urgent came on again 9 months later. I noticed it was in concert with the ABS Module Service warning because the tranny shifted strange like it was trying to overcome the ridiculous computer takeover to prevent you from moving in the middle of traffic. Each time the ABS clears the tranny shifts normal but the transmission warning stays on. I replaced the ABS module and that part works fine along with normal shifting, but with the Transmission warning locked on. I think there is a major defect with the 99 and 00 models and possibly others related to the control mechanism Volvo uses when the ABS warning comes on. All the blame has gone to GM transmission, but Volvo controls the software and apparently poorly.
