Yes β same Aisin AW8F22 8-speed automatic, same fluid, same service procedures. Repair costs are comparable between the two models.
Volvo's OTA updates occasionally push transmission calibrations that conflict with prior settings, especially on T8 PHEV models. A Volvo-specific scan can identify calibration version mismatches, and most are correctable with a targeted reflash.
Yes β we provide loaner vehicles for multi-day repairs including transmission rebuilds. Call ahead to confirm availability.
Typically 5β7 business days for a full AW8F22 rebuild. We stock common wear components, which helps reduce turnaround time.
Not immediately, but it indicates torque converter clutch wear that will worsen over time. Continuing to drive with shudder can contaminate transmission fluid with clutch material, leading to broader damage. We recommend addressing it within 1,000β2,000 miles of first noticing symptoms.
Same-day appointments available. Honest estimates, no surprises. We've been doing this since 1987.
