Thank you guys so much. On Saturday, 2 hours before leaving for vacation, I discovered that my front right wheel was leaking. I didn't have a glue set. We were really pressed for time. They're the only ones open on Saturdays. I called them, made an appointment and went there. Absolutely nice guys. They fixed the bike and the vacation can begin. Thank you again 👏👏

I contacted the service because of a dent on the body. They did everything quickly, the quality of work was excellent - the dent was gone.
I would like to separately mention the staff - they were polite, explained everything in detail, and did not rush me anywhere. It is obvious that they are professionals who know their business.

I am happy with the work, I recommend it!

I recently visited Bulldog Garage for an oil and oil filter change, and I was very satisfied with the service. I bought my car used, and they kindly checked it out for me for free. The mechanics were all friendly, professional, and most importantly, very patient with all my questions. The price was affordable compared to other places. I’m definitely coming back and highly recommend them. Thank you to the whole team!

How automatic transmission oil change works – our process in detail

Transmission oil change in Prague: technical details

Transmission oil plays a key role in the operation of an automatic gearbox — it ensures torque transfer, hydraulic system control, lubrication and cooling of components. Over time, every ATF (Automatic Transmission Fluid) loses its properties and becomes contaminated with wear particles, which negatively affects transmission performance. To keep an automatic transmission reliable, timely oil change is necessary — let’s look at the details of this process.

Types of automatic transmissions and specifics of oil change

Transmission type	Design features	Oil change specifics
AT (hydraulic torque converter)	Classic automatic with torque converter and planetary gearsets; main medium is ATF fluid.	Large oil volume (part stays in the converter). Filter must be replaced during service. Recommended ATF change interval: ~50–60,000 km (especially under heavy use).
CVT (continuously variable transmission)	Stepless transmission with steel belt or chain; uses special CVT fluid.	CVT fluid is thinner and contains special additives. Requires more frequent changes — ~40,000 km. Standard ATF cannot be used instead of CVT fluid!
DSG (dual-clutch transmission)	Automated transmission with two clutches (wet or dry); enables fast shifts without power loss.	Wet versions require regular oil and filter changes (~60,000 km). Special oil per specification (e.g., VW) must be used. Wrong fluid causes mechatronics failures.
9G-Tronic	9-speed automatic by Mercedes-Benz; sensitive to oil quality and level (filter integrated in the pan).	Requires oil per OEM spec (e.g., MB 236.16). Recommended oil + pan with filter change every ~60,000 km.

Partial vs. full oil change: what’s the difference?

Partial oil change: only part of the oil drains (~40–60% of volume). Gentler method, suitable for older transmissions or when service history is unknown.
Full oil change: performed under pressure with special equipment, replacing nearly 100% of the fluid. More effective, but in worn transmissions can loosen deposits and cause issues.

Risks of neglecting oil change

Loss of lubrication properties: old oil loses viscosity, dirt forms → accelerated wear of clutches and gears.
Clogged channels and overheating: metal particles clog mechatronics → pressure fluctuations, poor lubrication, risk of expensive repairs.

Fluid types and manufacturer requirements

ATF for conventional automatics: Dexron, Mercon, ATF WS (Toyota), MB 236.16 (Mercedes). Always use approved oil!
CVT Fluid: only special fluids for CVT — different viscosity and additives. Standard ATF is unsuitable.
DSG oil: OEM fluids (e.g., VW/Audi). Typical interval ~60,000 km.

Common DIY mistakes

⚠️ Wrong oil type → transmission failures
⚠️ Incorrect level → overpressure, foaming or insufficient lubrication
⚠️ Ignoring filter and gasket → reduced transmission lifespan
⚠️ Not following procedure → always comply with recommended technology and manufacturer parameters

👉 Recommendation: If in doubt, entrust the oil change to a professional service experienced with your specific transmission.
