With our long history of working with all car and truck manufacturers, let us try to address some common questions. We primarily specialize in imported vehical transmissions but welcome all makes and models and of course your beloved classics as well.

Common questions about Cost

We are happy to give an assessment if you can get your vehical to us. The most important thing is to have your transmission looked at when small things start to happen... do not wait, then it gets more costly.

How do I reduce repair costs?

Another cost saving is to have the fluid checked or changed regularly, Waiting for the engine light is never the best way to maintain your car.

Is there a Guarantee?

Yes, we warranty all our work. The make and year can be a factor but on average it's 1 year or 20K kilometers.

Do I need to make an appointment?

if you feel there is something serious then yes, please book an appointment. That way we can make time in our shedual to get it repaired.

How long do repairs take

This also depends on things like is it just a fluid change and flush, 1 day. A full rebuild with parts, 2-3 days. Older cars pre 1970 may take extra time due to availablity of parts.
