Hi All,
I changed the ATF from the Stafford. After that also i had that small jumping issue once in while when i accelerating from idle. After 2 or 3 weeks car start to stop very silently in the Parking gear. So i did a engine tuneup. After that problem solved and all the noise came from the engine no-more coming. I feel acceleration is smoother than previously and gear shifts happens properly without any miss.
Thank you all.
