Hi Scotty. Thanks for providing great advice to the auto repair and buying laypeople. I have enjoyed many of your videos since finding them recently.

I have a 2007 Hyundai Elantra I bought new. It now has 193,000 miles. It's been a very reliable car that seems to want to last 2 or 3 more years.

The only thing wrong is the AT occasionally gets stuck in 3rd gear when getting on the interstate. After a couple of minutes, it always shifts into 4th gear.

A transmission mechanic plugged in his diagnostic device and said the car needs a new transmission.

He said quite vehemently, not to ever drain and refill the transmission fluid, or more importantly, NEVER flush the fluid as it will send all kinds of tiny metal transmission particles into the gears that would destroy the transmission for good.

He said, if you haven't changed your fluid in more than 60,000 miles....don't do anything ever to the old fluid. He said to leave it in the car as long as it will run.

I haven't changed the transmission fluid in over 100,000 miles now.

Is he right? Can I at least drain the fluid, clean the pan filter and replace with new fluid?

I would like to keep the car as long as it is reliable and safe to drive.

Thanks for any advice.
