Thread: bad pcs?

That is a lot of mileage for the trans to be original! Not too many make it that far for sure. Every different carline / engine / gearing combo seems to have a direct effect on the 4th clutch hub going bad. Some only make it to 70K, some with well over 100K dont look too bad, and just as you mention driving style and habits also have a large effect on the life of the shaft. If you are thinking of replacing the shaft then I would suggest installing a Transgo shift kit also as this will give you an upgraded boost valve and new pressure regulator valve spring that goes in the valve body as well as new accumulator springs to quicken up the shifts a bit. It is not a performance kit, just makes the trans work nicer in stock form and helps overcome some common problems.

Clean red fluid doesnt mean the trans is in good condition and may have been in poor condition and was flushed to try to help or cover up a problem before you bought the car. Seals do wear and shrink over time and can also cause problems after the car is warmed up. If you plan to drop the pan and change the filter then just use Dexron 3 fluid in it and it will be fine since that is what it had before. A lot of people have had problems after switching to synthetics with these transmissions with slippage problems. If the trans is fresh then it is worth the cost but its not worth the extra money to hope it will help out a trans that isnt working properly.
