1998 Toyota Corolla Transmission Fluid

Hi, I own an automatic 1998 Toyota Corolla with 133,000+ miles on it. I recently got my oil changed at Valvoline and they suggested that I change my transmission fluid. My question is: Would I be taking a HUGE risk if I let Valvoline or Jiffy Lube change my transmission fluid? Or should I take my car to a Transmission Specialist and let them change my transmission fluid? And which is better: flushing or draining the transmission fluid and why?

Thanks.

Draining and refilling is OK, along with perhaps a filter change. NEVER let anyone flush your automatic transmission.

CHANGE the transmission fluid, don’t flush it.

As MC said “CHANGE the transmission fluid, don’t flush it.”

Let me add: Keep away from the quick change places. We hear far too many horror stories about them. Some may be fine, but many pay the help little, demand fast changes and that results in a high percentage of errors. Too many live by selling you something you don’t need at inflated prices.

Find a good local mechanic and stick with them for your needs.

Don't go to the quick lube places, even for directions.
