    I have also had some problems with Pressure control solenoids going bad when they get hot witch would increase pressure to high during shift points. But most of the time they will set acode.

Shift solenoid b how do you fix it ?

Does this problem set a code in the computer? Try clearing the code and see if that fixes it.
Next step would be to drain transmission fluid and change filter and try an additive like SEAFOAM to the transmission.
After that you are probably looking at a new tranny....sorry.

You are going to need a transmission shop. Mazdas do not always throw codes. You have an early OBD transmission, which do not send out many codes.

theres a good chance that,if the tranny wasnt serviced often enough the filter and the fluid wasnt any good. so possibly with the new parts and new filter and fluid,it should extend the life alot

dont listen to this guy never flush your transmission thats a quick way to kill it. do a pan drop fluid filter change. refill with dexron 6. but ill tell u now ur problem is most likely the PRESSURE CONTROL SOLENOID in your transmission. may or may not throw a CEL. causes harsh shifting and slipping etc very common on the 4t65e trans. can happen any time and usually symptoms most obvious when engine reaches operating temp
