Experiencing car trouble far from home is never ideal, especially when it involves a major component like the transmission. This was the situation we faced with our 2000 Toyota Sienna minivan, boasting 150,000 miles, during a trip 500 miles away. Seeking a trustworthy solution, we consulted my dad’s mechanic, who diagnosed a transmission issue and recommended a reputable transmission shop, an ATRA participant, for further assessment.
After diagnostics at the transmission shop, the verdict was in: a transmission repair or rebuild was necessary. Opting for the more comprehensive and reassuring route, we chose a transmission rebuild, despite the higher cost. However, just four hours and approximately 240 miles after collecting our vehicle, the dreaded check engine light illuminated.
The diagnosis this time pointed to a transmission code: P0770, indicating a shift solenoid E fault. We were informed that a failure of this Solenoid Car Part could potentially lock the car into second gear. Limping home, we took the minivan to a local transmission shop that participated in the warranty program of the original shop. Surprisingly, they could find no fault and sent us on our way.
But the relief was short-lived. Another 250 miles later, and just 150 miles from home, the check engine light reappeared. Back to our trusted local mechanic we went. He confirmed the same P0770 code and reset the light. The original transmission shop, upon receiving the code information, insisted they couldn’t diagnose the issue remotely and advised us to drive until the light recurred.
Following their instructions, approximately 200 miles later, the check engine light illuminated once more. This time, we took the vehicle to the local transmission shop again. After eight days, they identified the problem: the solenoid valve. However, here’s where the complication arises. They are claiming that although the solenoid valve resides inside the transmission, it is not considered part of the transmission itself because it’s an “electrical” component, while transmissions are deemed “mechanical.” They quoted a separate charge of $535 to replace this solenoid valve.
We argued that a transmission rebuild should encompass all components within the transmission, ensuring flawless operation, at least for the duration of the 15,000 mile – 1-year warranty. The local shop is now in discussions with the original shop about warranty coverage. If they fail to reach an agreement, we are told we would need to deal directly with the original shop, located 500 miles away. Currently, our car remains disassembled at the local transmission shop, leaving us in a state of uncertainty.
The crucial question remains: Is a solenoid car part, specifically a solenoid valve inside the transmission, considered part of the transmission for warranty purposes? Should the repair of this solenoid valve be covered under our ATRA warranty following the transmission rebuild? We urgently need our car back in reliable condition to travel for the holidays and are seeking clarity and resolution without incurring unexpected and potentially unwarranted expenses. Any guidance on navigating this solenoid car part warranty dispute would be greatly appreciated.
