When driving the transmission is slipping through all 4 gears and when it's in third and fourth gear it is like they're gone.
Both shift solenoids have been replaced.

Good morning.

How long since you changed the fluid and filter? It may be a clogged filter.

Beyond that, it is an internal failure. If the fluid change does not resolve it, the transmission will have to be replaced.

Thank you for your response. I know 1 code was for the o2 sensor and the other code was the transmission controls module. I will have to find the paper the codes were right on.

There are many codes for the module. See if you can have someone check it for you.

A parts store will do this for free.
