This time we want to clarify some doubts based on your questions related to the repair of Automatic Transmissions .
In all cases is it necessary to fully repair the Automatic Transmission?
It is best to check the symptom of the vehicle, as in most cases are due to external causes such as sensors, solenoids or body Valves
How do I know if it is a fault that requires repair?
When the transmission warning light comes on, the modules automatically put the transmission in safe mode, which causes the applications to be more abrupt and not to make changes automatically, so it will be necessary to take the vehicle to a specialized workshop To identify the fault code and to be able to give attention to the problem.
And how do you know if there is an internal problem?
Generally are other types of symptoms when there is an internal problem, we present the ones that we believe are the most common:
Loss of Power, that is to say sometimes does not have the necessary force in the advance : This is due to the internal skating of the components like the Clutches.
Loss of some Speed; That is to say that it does not make some change, like to be without 2a. Or without reverse, etc.: This is due to some damaged component such as a broken band or some mechanical part.
Skating when trying to override : This is due to some damage to some internal component, which causes the transmission does not have the necessary force.
It takes time to enter the speed of the drive or the reverse, due to a wear on the components that cause the speed not to enter in time.
Once detected that it is an internal fault, which is what is recommended to do, is it enough to only change the damaged parts?
Never, since the transmission was damaged by a fault of the internal operation, and must be corrected both the consequence and the cusa that originated the problem.
Then what is the repair of automatic transmissions?
All wear parts such as disks, belts, alloys, pistons, teflons, turbine, seals, filters, etc. must be changed. As well as make a complete service to the valve body or, if necessary, change it. And obviously change the damaged hard parts such as planetary, oil pump, etc.
Is a transfer in exchange?
In our case we handle the transmission in exchange for the sole purpose of making the delivery faster, since the transmission we installed carries all the new internal components, only in that way can we ensure some guarantee that the work is in the proper way.
What warranty should I require in a repair?
When a repair is carried out properly it is as if the transmission were new so under normal conditions of operation and service it should last the same as when it was new.
In our case we guarantee the transmission for a year and we give a free maintenance service to the six months.
