Diagnostics & fault assessment
A shift concern needs context. Start with the vehicle, the exact transmission, and what happens on the road.
SPECIALIST ATTENTION TO YOUR TRANSMISSION

Share the full fault codes, scan reports, and previous work. A code is useful evidence; it does not by itself establish the repair.
The next step
Discuss what additional assessment is needed before a service or repair scope can be set.
