TRANSMISSION SERVICE

I have a 1999 Mazda Protege LX
It currently has 140,000 miles.
I had the transmission fuild (not the transmission filter) in the transmission changed at 110,000. As it is 140,000 now I think that it is time for another service. Also the gear shifts a little hard than before but overall it works just fine.

The previous owner also informaed me that the transmission failed at 80,000 miles. I am not sure if it was either rebuilt or was replaced as brand new under warranty.

But I wanted to ask yo if it is wise to get a transmission service done to such a transmission or just to let it run like it is currently! I dont know if it will start slipping after the transmission service!

If you do recommend the transmission service then what kind of transmission service I should have done.

1) Drain and Fill fluid and change filter

or a

2) Tranmission Flush by the machine

I am not sure if the tranmission flush machine is reliable enough or will blow seals with pressure or cause other damage in the transmission.

Thankyou for taking time to answer my question!

I have seen trannys go bad after a transmission filter change. Immediatly after. However they were always ford or lincolns and had never had a filter changed until it was around 100,000 miles. IT just brought the problems to the surface and would have happened anyway.

Here is what I recommend. Change the filter and pan fluid at 30,000, 90,000, 150,000 etc.

Flush all the fluid at 60,000, 120,000, 180, 00 etc.

Don't be afraid of the transmission flush machines.

How does the fluid look right now?

If it isn't too bad, just do the filter and pan fluid. If it is burnt, I would flush it and then change the filter and pan fluid.
