Thank you for your prompt response.
The topic under discussion pertains to the concept of seven-speed.
The vehicle has accumulated a mileage of 101,000 kilometers.
A gear box service was performed on the vehicle around 15,000 miles ago, coinciding with its purchase. It is my understanding that the prior owner had also had this issue.
Based on my understanding, appropriate fluids were used and the fluid level is satisfactory. The Indianapolis (Indy) products that I employed have consistently shown high quality, since I have relied on them for an extended period of time.
The temperature of the transmission fluid remains within an appropriate range, typically about 75 degrees Celsius, while operating under high temperature conditions.
The aforementioned alterations are acceptable; however, transitioning to the third gear when decelerating on a downward slope at around 26 miles per hour.
It is peculiar.
It seems that there are no other methods available for inspecting the transmission fluid, except from the process of emptying it.
