Hi Scotty, or anyone,
I have Toyota Corolla 2004, automatic transmission, 135K miles, It starts and drives good but when it's cold it doesn't respond well to
acceleration when stopped at a light. It needs to be revved up to 3000 RPM before it starts picking up speed. Once the car runs for about
15 min, and the engine is warm, it drives with no issues. I cleaned the MAS sensor, changed transmission fluid (no filter change), changed
the air-filter, oil and oil filter, and antifreeze as part of the maintenance. No diagnostic lights have popped up. What should I do or change?
I want to keep the car until the wheels fall apart.
Thanks!
Have a pro transmission guy check your transmission.
Yaser, what makes you think it is transmission? When in warm weather it has no issues.
You changed and checked fuel and air related issues. Considering the symptoms, having no code as well as all the things you have done, for me thinking that the transmission may act up. (I’m guessing solenoids in your transmission may be faulty., but you need further diagnose).
Can you help me understand your logic by how the cold weather affects solenoids in the transmission, and when it's warm the solenoids in the transmission are not affected at all? By cold I mean anything below 32F.
So, no real experienced auto-mechanics here on this forum willing to help solve the problem?
