Hi,I am new to this forum.

I bought Montecarlo LT 2006 couple of months ago and this is my first car.
I went for oil change and the mechanic recommended to change transmission fluid as well.
My question is --
1.What is the best way for replacing transmission fluid? and the type of fluid that suits my car?
I heard that the performance of the vehicle decreases if transmission fluid is replaced by flushing it out.I am not sure if this is true or not?If this is true what is the other way to change the fluid?

I really appreciate your suggestions!!!

 

How many miles on your Monte? Best advice is just do a pan drop flush on the trans.

 

just drop the pan and do a filter change and i think after a pan drop you need 6 quarts of dextron vi

 

like said use Dex VI and only do a pan drop. do not have them flush it.

if the clutch packs are warn, a full flush will remove too much friction material and the trany will slip.

 

i agree with dex VI it calls for it and it is the better fluid to boot i also have the 7th gen it calls for it

 

Sorry to hijack, but I had to comment/question. How would a flush remove friction material? I work for an airline engine manufacturer and we commonly spray friction materials onto parts to be used as, effectively, a brake. I don't know what processes the auto industry uses, but assuming they're even close to us, I'd almost guarantee that this stuff doesn't just rinse off by being flushed.

On to the point of the post though, I just did a pan drop and filter change two weeks ago because I had some burnt fluid and it definitely helped.

 

If a trany hang had regular fluid changes and the fluid breaks down. When the fluid breaks down the friction material on the clutch pads comes off and is suspended in the old trany fluid. If you flush the trany you end up removing most of this friction material. Without it the trany will slip. Game over.

Drop pan add new dex VI call it a day

 

Hey monte carlo 3811, I have 82000 miles on my car.

Thanks all for your responses
