1997 Mazda 626 Question: How do I flush or change transmission fluid and filter?
Good chance the problem is something other than the transmission. Changing the fluid would most likely be a waste of time and money even if it was a tranny problem. Fluid change is for maintenence not a repair. More likely your problem lies with fuel, ignition, etc. Suggest you have diagnosis done first. - milesauto
This sounds more like a faulty exhaust issue. Get code read for free at autozone and post on here. Suspect you will get o2 sensor faults. Problem will either be those o2 sensors or the cat. converter has fouled and is backpressuring the exhaust toward the engine. - csubak30
