Frequently Asked Questions
How often should Mercedes transmission fluid be changed?
While Mercedes claims 'lifetime' fluid, we recommend ATF change every 60,000-80,000 km for optimal transmission health and longevity.
What causes Mercedes transmission problems?
Common causes include degraded fluid, worn valve body solenoids, failing torque converter, or electronic control (mechatronic) issues.
Can you repair the 9G-Tronic transmission?
Yes, our specialists are trained on the latest 9G-Tronic units including mechatronic repairs and software updates.
Is transmission rebuild better than replacement?
A proper rebuild is often more economical and can restore like-new performance. We only recommend replacement if the case is damaged.
How long does transmission repair take?
Simple valve body repair takes 3-4 days. Complete overhaul requires 7-10 days for proper rebuilding and testing.
What warranty do you provide?
Transmission repairs carry 1-year warranty. Complete overhauls come with 2-year warranty on parts and labor.
Customer Reviews
Transmission was jerking badly during shifts. Metre Per Second diagnosed valve body issue and repaired it. Shifts are butter smooth now. Great expertise in automatic transmissions!
Shudder during acceleration was concerning. They diagnosed torque converter issue and fixed it perfectly. Saved me from a much more expensive dealer quote.
Complete transmission overhaul done with genuine parts. The S-Class shifts like new again. Professional work and transparent pricing. Highly recommended!
