Trans Flush vs. Fluid Change?

[JML07denali]

In my opinion, when you drop the pan you are only replacing about 5 quartz of fluid. If I recall there is about 11-13 Quartz in the whole transmission. Seems like it would be a waste to just replace a few quartz? Just my 2 cents.

It's not a waste. While it's true you're not replacing the fluid, you're more refreshing the fluid.

I haven't found a suitable pan with a drain plug yet (don't want to spend $300 on a fancy pan) but what I ususally do is replace the pan with one that has a drain plug. Then every other oil change I'll change out the 5qts of fluid in the trans and eventually you'll have pretty fresh fluid throughout the system.

Based on my experiences with flushes when I was younger and a better understanding of why you shouldn't do it now I'll stick with the occasional 5qt change out.

I agree

A 4L60 holds 11qts of fluid, if you just drop the filter and refill you've still got 7+ qts of the old fluid.

I recommend doing the flush.

I'm doing mine next week and I'm doing the fluid change but substituting a quart of fluid for a quart of Lubegard.

The big question is why the heck didn't GM make a pan with a drain plug?

I bought these and is very suitable. Last time I brought my truck in for a transmission drain and fill, I had them replace it with this pan.

Yes I have seen this before. Unfortunately it doesn't fit 6.2 L.
