The transmission shift solenoid has been replaced 3 times already on the vehicle. The check engine light recently came on and the reason is ths part malfunctioned again. What could be the casue of the frequent failures of this part? The parts and labor to replace this last time cost about $450.

Hi Bruce Houk,

Thank you for the donation.

To understand the problem better, can youplease provide us the exact trouble code for the shift solenoid?

When was the first time the solenoid was replaced and the last time?
Was the trouble code the same each time?
Each time it was replaced, how long did it last?
Were the parts new or used?

I could not find any TSB or recalls on the item in our database but a google search seems to indicate this is quite a common fault.

Solenoids are electrical components and there is no definite life span for them. How long they last is anybody's guess.

Electrical components are unpredictable so there is no definite answer for you. What I can say is that these solenoids, being made up of coil windings do fail over time as they are subjected to heat, from the trans fluids and when being energised by electrical currents.

From another point of view, the connectors are on the transmission and I have seen many cases of which contaminations to the terminals causes them to fail. When contacts deteriorates due to presence of water and in some cases battery electrolytes, as the battery is above the connectors, the malfunction would be detected by the computer.

When a fault is traced to the solenoids, replacement is recommended though at times cleaning the connections would suffice.

Hope this answers your question.
