I have an 03 QCSB Hemi with about 86000 miles. I bought it at 80000. This is a list Ive come up with that I want to do. Maybe down the road some headers. This also isnt in order I want to do the stuff and I allready have the catback w/flowmaster S44 and the CAI. What are your opinions? Good start? Also im a mechanical retard but I want to learn.

1) Catbak
2) CAI
3) Y-pipe
4) Trans flush
5) TMR mod
6) PCV valve change
7) SC programmer
8) E-fan
9) Tranny line pressure booster
10) Cab roof lights
11) Clean throttle body
12) Clean TPS (DIY)
13) Change all 16 plugs

 

Do a tranny filter change not a flush.

Be sure to change the valve body ring carefully. You can also inspect & clean the speed sensors too while your down there.

 

Why just a filter change? Just changing the filter will still leave 3-4 quarts of fluid in the TC.

 

That's not much at all considering. By doing a flush your stirring up goop and NOT replacing the filters.

One tiny piece of lint ( or worn aluminum ) is all it takes to screw up your valve assembly and then it's teardown time.

Pushing all the crap backwards out your system is not the best way to maintain it, changing 1/2 the fluids ( more if you purge your cooler lines ) is better than a flush. A filter change swaps out 7 quarts, the cooler & lines, about 3 so only 3 old quarts of filtered fluid remain in your trans. Not too bad as it's all clean & should stay that way.

It's just my 2 cents. The flush is probably more expensive than going under and doing the filters yourself also.

 

What about disconecting the return line at the cooler and flushing it that way. I was planing on changing both filters. Disconect the return line and start it till it stops the pull the pan off change the filters. Put pan back on dump some fresh fluid in it. Start it till the fluid coming out the return line is "new" fluid. Shut down reattatch return line top it off. That way your not back flushing it. Its all going through like its supposed to. The proper route. I believe dirtydogg has a DIY on it.

 

i would also change the rear diff oil and tranfer case fluid. haynes manual recomends it at 72,000 miles

 

The way you describe it is not horrible, just be sure you are on the cooler return line.

From your list description it sounded like a service centre flush in which filters are not replaced. That is what I recommend against, you are merely using the internal pump to drain it from the tq & cooler.

 

Might as well do the transfer case too while you have all the atf4+

 

This is the most pre-conceived notion out there. 100% FALSE
The fluid that's pumped out is just circulating like normal. You unhook the line that puts the fluid into a bucket rather than back into the system. No pressure involved either.

Yep, sure can, but if there's metal in there, that means there is some sort of damage and that might mean you lacked maintenance. This I'm not arguing as we could sit here all day and agree with one another. The only thing I want to add....Filings in oil....That is what the filter is there to do.

Another false preconcieved notion that is not correct. Flushing the system is 100% safe. When you do a flush, the flow through the transmission does not change direction. When you are flushing, your transmission does not know any different. The flow is normal. The flow is normal because you use the transmission pump to push the fluid out. ANY PUMPED OUT FLUID must go through the screen just as if you were driving your truck down the road.
It's when these places want to use cleaning agents to flush your tranny. Then be very weary!!!!!

A standard flush takes ~17qts give or take a qt. You won't put any stress on the tranny by unhooking a line, the fluid does not flow backwards, the fluid flows through the screen as normal so any filings get stopped by the screen just the same as if it were closed up driving down the road.
I've done HUNDREDS of flushes. Never once had an issue.

I do reccomend dropping your pan to change your filter first, but before that, unhook a line and pump the pan empty first. There's a HOW-TO in the FAQ section. I think Silverbullet posted it??

 

Nice ideas on things you are going to do to your truck.

When I did my trans filters I changed 17 qrts of my fluid also by disconnecting the trans line and starting the truck briefly to let the trans pump it out for me.
