Figure the flush is 155.00 plus tax, I figure the pan drop filter fluid would be two hours shop labor plus parts. I think their shop rate is 125.00 an hour.
Thank you

that is pretty cheap, up here its 1 hour labour and the cost of the fluid

 

Seems logical to me to drop the pan. The 1rst 50k miles the tranny is getting broken in. There will be some metal flakes from the break in. Flushing it forces fluid through the filter.If there is dirt in the fluid it will clog the filter. It might evn be worth going to the junk yard and getting the tranny lines that connect to the radiator then you can use an air hose to blow the fluid out of the radiator.

 

there will be some material on the pan magnet and some in the filter...never seen a filter clog even in a failed transmission. if you need or want to clean a smear of debris from a magnet and change the filter drop the pan.

exchange machines do not force anything anywhere...they use the vehicle oil pump to move fluid thru the system as it would in normal operation. Why blow out rad lines when the purpose of the exchange is to move fluid through the entire system, and any crud in suspension, out to the waste tank.

 

I've never seen brown and smelly tranny fluid. It must take a lot of abuse to get to that point. A pan service should replace the additives.

If you want, you can do a poor mans flush pretty easily:

1. Buy a 5 gal bucket of transmission fluid.
2. Drop the pan and put a big tray underneath.
3. Attach a jumbo funnel to vinyl tube , jam the other end into where the filter goes.
4. Start vehicle. Keep the funnel topped up and switch through the gears until the fluid comes out clean.
5. It goes pretty fast. Stop when it starts to make a loud slurping sound. Top off to required level.

 

...look at your pics and you'll see brown fluid.

 

It looked more dark red to me. This is what brown looks like (on the right). That transmission had gotten more than a few hot suppers.




Once out of the jug, ATF doesn't stay that bright pink color for very long.




By the way, do you have financial stake in servicing GM vehicles?

 

looks like old worn old fluid to me...probably why its being changed.

If the fluid is brown as your sample, something went wrong

the only stake I have is not agreeing with what your selling. "trans fluid colour and smell is not an indicator of fluid condition"

 

The fluid was worn. But not brown.

The image was one of many from a google search. Just illustrating what brown looks like.

I didn't say anything about smell, but I don't think color is, no. As is the case with engine oil.

 

maybe i'm getting wrong information from my dealer training transmission courses.

Transmission malfunctions may be caused by these general conditions:

1. Poor engine performance
2. Improper adjustments
3. Hydraulic malfunctions
4. Mechanical malfunctions
5. Electronic malfunctions

Diagnosis of these problems should always begin by checking the easily accessible variables: fluid level and condition, gearshift cable adjustment. Then perform a road test to determine if the problem has been corrected or if more diagnosis is necessary.

Burnt, discolored fluid is a result of overheating which has three primary causes.
