In this article, we go over some of the most common problems with Opel automatic transmissions and common causes.
Opels with a 6-speed 6T40 transverse automatic transmission, designated as Hydra-Matic, can suffer from inoperable TCC lock-up. In some cases, the TCC will lock-up in a very harsh manner. In general, this will have a negative impact on fuel economy and can even cause transmission fluid overheating.
The TCU will detect if there is an issue with TCC engagement and trigger a check engine light, so there will be corresponding code.
Possible causes and solutions
Older Opels that use a 4-speed 4L30-E automatic transmission in longitudinal configuration have a fairly common issue that affects upshifts. It will show up as slippage or delay when shifting into 2nd or 3rd gear during accelerations.
In more severe cases, this can also cause harsh gear changes coupled with a noticeable shoulder. This issue is likely to trigger a check engine light, meaning there will be a code stored in the DTC memory.
Possible causes and solutions
Smaller Opel cars that use an automated transmission called Easytronic have a common problem, which will render the car inoperable. The symptoms are a letter ‘F’ that will be illuminated on the dashboard, and the car will refuse to start. In most cases, there will be one or more related codes stored in the DTC memory.
Possible causes and solutions
Opels that use a 6-speed 6T40 transverse automatic transmission, designated as Hydra-Matic, have a fairly common set of issues. They will manifest themselves either as a loss of reverse together with 3th and 5th gear. Usually, this will happen out of sudden and will not go away when the engine cools down.
In most cases, this issue will not trigger any warning lights on the dashboard.
Possible causes and solutions
Opel Vectra and Antara, equipped with Aisin AW55 5-speed automatic transmission, suffer from an issue that is quite common. This will show up as intermittent shift flares during accelerations that affect upshifts from 2nd to 3rd gear.
Sometimes, this will also cause harsh downshifts from 3th to 2nd. At the start, this will be more prominent when the vehicle is cold but might get worse with time. In most cases, this issue will trigger a check engine light, meaning there will be a trouble code stored in the DTC memory.
Possible causes and solutions
Opel vehicles are fun to drive and generally inexpensive to maintain. We recommend having the transmission serviced at the recommended interval to minimize potential issues down the road.
