    Re: Transmission Fluid Change

    For rubber gaskets I take a shop rag soaked in gasoline, and carefully work my way around using different parts of the rag for each little section. Don't pull too hard or you might tear it in half.

    Re: Transmission Fluid Change

    That might have been your problem in the first place. Since your plug is at the rear, you'd want the back of the car higher than the front so the fluid will run towards the front of the casing. You left out buckets to fill up, and rags for your hands. One guy got covered in fluid when he did his. Odd enough, he sounded more proud than bothered by it.

    1. Change the fluid and fluid filter.
    2. Start the engine.
    3. Depress the brake pedal and move the shift lever through the gear ranges, pausing a few seconds in each range. Return the shift lever to the PARK range.
    4. Raise the vehicle on a hoist. The vehicle must be level with the engine running and the shift lever in the PARK range.
      Caution

      The engine must be running when the transmission fluid fill plug is removed, or excessive fluid loss will occur. Transmission fluid may be hot. Since the actual fluid level is unknown, stand clear when removing the fill plug. Have a container ready to capture any lost fluid. Do not turn the engine off with the fill plug removed, as you can be injured by hot transmission fluid being expelled out of the oil fill opening.
    5. Let the AT fluid temperature rise until it has reached the specified value. Remove the transmission level hole plug (36).
    6. If needed, add DEXRON®III automatic transmission fluid in increments of 0.5 L (0.5 qt) until the fluid drains from the threaded hole plug.

      Important

      If the level hole plug (36) and O-ring (37) are not damaged, they should be reused.
    7. Allow fluid to finish draining out of the plug hole. Inspect the level hole plug (36) and O-ring (37) for damage. Install the transmission level hole plug (36) and tighten to the specified value.
    8. Wipe any excess fluid from the transmission with a rag or shop towel.

    how many quarts of trans fluid do i need? is 7 quarts correct. i went to CHECK the trany fluid level and the same thing happened car was on in park level with the rear a little higher than the front this time took out the FILL plug that i circled #36 on the diagram and fluid came out alot i even put the side with the fill hole a lil higher
    1. should i jack up the left side with the fill plug ONLY to fill/check ?? someone else posted a couple pages back that they filled it this way
    2. could this be the reason why fluid comes out someone has done it this way before??
    3. is it safe for the body to be jacked up on one side??
    4. so if it was done this way is it ok that some spilled out half a quart or less
    im about to give up n take to mechanic plus my jack broke today


    sorry for so many questions but it seems pretty simple especially if i think of myself alittle mechanically inclined i work at a body shop i help remove subframes, transmissions , motors suspensions i also removed my engine and trans on my old chevy and have done several filter canges on TH350 n TH400 's iwould like to do all 100,000 mile services like rolls but cant finish this one

    Re: Transmission Fluid Change

    I had mine powerflushed by the Cadillac dealer, and they are on the hook for any failure that results. They did not drop the pan or clean the magnet, and they did not change the filter. They said Cadillac recommends against changing the filter now. $212.65.

    A simple drain and fill should be cheaper, especially at a regular place, not the Caddy dealer.

    If you have doubts, there's no shame to having someone else do it. Its a messy job. How many miles are you at ? Under normal conditions the fluid is good for 100,000 miles, 50,000 under hard conditions...real hot climates, racing all the time, etc.

    The meter was reset at 85000 miles. I reset mine accidently. How was the fluid when it spilled out ? Black and nasty ? Clean ?

    Re: Transmission Fluid Change

    If I were in your shoes, I'd have someone else clean up after me. I'd want the tranny totally filled (you've lost some fluid) and that requires running the engine with the transmission in park while its filled. The proceedure is in a DIY thread.

    If you have the bucks, let the Caddy dealer do it, go with the powerflush for $200.

    If money is tight, drain and refill at a chain of specialists, making sure first that they know how to fill it right.

    I've got 104,428 on mine tonight and mine is a 2006. It loves to be driven, but the wobbly tensioner is keeping me from playing. I got up too late to do anything but add a splash of oil to it today, but maybe I can change out the tensioner tommorow.

    Why don't you fill in everything you've done for 100,000 miles on this thread ?

    Re: Transmission Fluid Change

    Ok gang i'm about to get my tranny fluid changed on my 2004 3.6L VVT CTS, which has about 112,000 km right now. Now my question is should i just do a drain and fill? powerflush? or drain, drop the pan and change filter and gasket?
    Not to sure which way to go here, is it necessary and advisable to replace filter and gasket?
    Just want to make sure i do what's right and won't end up damaging the vehicle...

    Re: Transmission Fluid Change

    I went with the dealer recommendation. They said my fluid was just a little dark, so after getting their assurance that they'd stand behind the proceedure if I developed any trouble, I let them do it. They didn't drop the pan or change the filter. Under $250 USD.

    They didn't drop the pan or change the filter? Why my friend?
    I would think the dealer if anybody would probably know what's best for the CTS correct?
    How many litres does the 2004 3.6L V6 VVT CTS require, i've read on here that it's 7Litres, is that correct? much thanks again!!
