Ok should I change the Trans fluid or not I have heard that the new fluid has been known to wear down the clutch,s due to the high detergents in the fluid and I do not want to have to rebuild this trans. The tranny is a PTS full billet with a lock up 9/11 convertor with about 5,000 miles on it , and has not been done before . Is there a way to just filter out the fluid I already have and just change the filter?? Thanks, ED Ps The trans is great I just wanted to change all the fluids on the car...

Here are the two general trains of thought I've heard on this topic.
1) Transmission fluid contains detergents. The idea of replacing the fluid every so often keeps a nice level of detergent in the fluid keeping all of the internals nice and clean. It's also a nice "health" check as you can see if you have any clutch residue or metal in your pan. Checking the color and odor of the fluid is typically a good tip off as well.
2) Transmissions are fairly well sealed components. Being that way, the other idea here is that there's very little dirt that will ever get into your transmission, so the detergents aren't all that necessary. Add to that the fact that transmission fluid doesn't lose it's lubrication properties quite as easily as say motor oil.
I won't be so bold as to recommend either route. I think that's something you'll have to weigh for yourself. I'm sure others will chime in as well.

The idea that trans fluid stays clean because it is a sealed component is bullsh!t. It won't get dirt from the outside (usually) but it gets plenty of debris from normal wear on clutches, bands, and bushings. Some of it is too small for any typical filter to catch. The oems are catching up on this which is why the new super duty ford has a cartridge filter in the cooler line that looks like a roll of toilet paper. It is designed to catch ALL of the debris in the fluid. The speed at which the viscosity breaks down is dependent on two factors: quality of the fluid and the amount of heat that it is exposed to.
Grumpy is right though. Do whatever YOUR trans. builder tells you to do. It's his baby.
I change all of the fluids in my GN at rediculously short intervals.
