Should I change the transmission fluid?
 

I have a 1998 Toyota Camry with 127,000 miles on it.

Should I change the transmission fluid?

Is this an automatic?

If so, my opinion is to change the fluid at at least every 50K miles. Change it all not just in the trans pan.

Don't do flush with chemicals. Use a procedure or machine that does not use external force to move the fluid out. But uses the trans own fluid pump to do this.

If a 4-cylinder engine. The auto trans differential also has its own fluid compartment that needs changing.
