Rebuilt or Repaired Transmission Assemblies |
|
|
Unlike manual gearboxes, Somerford Mini do not offer a rebuild and repair service for automatic transmissions, other than for superficial repairs which do |
not involve the internal workings of the transmission. This is due to the very complex nature both of the work involved and the equipment required to carry |
out the work. |
|
|
|
We advise customers who require rebuilds or repairs to deal directly with an automatic transmission specialist - we can point you in the right direction |
towards a reputable specialist, if required. We should also mention at this point that we carry out automatic to manual power unit transplants in our |
workshops. Automatic engines are unique and will not fit a manual gearbox, so if a Mini is to be converted to manual gearbox the whole lot has to be |
changed. This apparently drastic measure doesn't have to be too expensive if good secondhand components are selected, and it frequently represents a |
very cost-effective way to get your Mini back up and running when otherwise faced with a huge bill for automatic transmission repair. |
|
|
|
|
|
As a result, we do not attempt to hold comprehensive stocks of internal components for automatic transmissions (as the following page will show). |
Instead we limit ourselves to parts which by our own experience we consider may be fitted successfully by our customers - and even then, sometimes only |
by the more experienced ones. As always, though, if there's anything else you require, please contact us and if it's available we will obtain it for you. |
