Thread: 04 Comp G trans filter question?

The filter is the same for all 4T65's.. Comp g is no different. Same filter fits all the 4T60's as well.

If you are doing just a pan drop and filter you need at least 7 quarts. GM FSM states 6.5, I've found on tons of them that it's more like 7-7.5. If your trans is in good working order then a flush will not hurt anything. The only difference between a service and flush is you have less clutch material suspended in the fluid when you are done flushing. A flush should never hurt a trans.

That's what I thought...I figured it only made things worse if there was already substantial damage or if one of those savage machines were used..haha. Yeah, I actually forgot about that - I did hear somewhere you could get about 70% of the fluid with just a change (the whole trans takes 10qts, correct?) so that's actually not too bad... I guess I still don't know which I will be doing but at least neither option would hurt much either. I just have to wait on finding another job so I can actually buy the rest of the fluid XD
