Check it idling at operating temperature on level ground. If it is brownish and smells burnt, then it needs to be changed, but may be too late. Your owners manual will give you the change schedule. I usually do it at 100K need it or not.
Why dont u want to flush ?Just DON'T flush it!
is it expensive?IF you want to get that far into a 4T80E transmission fluid change, I would recommend taking it to a GM dealer for one of their Spring Specials. They use vacuum fluid change machines and refill the entire system with the new recommended synthetic DEXRON-VI, which is 100% backwards-compatible with the old DEXRON-III.
A complete garage floor jackitup fluid change is NO FUN on one of these cars, and the risk of losing check balls from the valve body is very possible. You WILL need a proper service manual.
There is no "filter" per se.......there is a screen which gets cleaned. That's no fun to get to, either.
the caddy dealer near me is offering a special 129 for a flushProbably $140 - $160 depending on the dealer...............given today's oil prices, maybe a bit more.
i thout there was no filter on these cars i thout it was just a screen im confused is the screan what is in the tranimision flush machine im confused her i did read the thing on the flush in the forums and that is just waht my friend told meFind a new dealer if they told you that bull crap.
You can honestly change the fluid yourself fairly easily.
Crack some pan bolts, let the fluid run out a bit, crack them all, let it finish draining.
Remove rest of bolts, set pan down gently and clean off magnet.
Inspect gasket to make sure it is still usable, if not go buy a new one for $12 or so.
The sump pick up screens should be right in front of you if you are under the removed pan, replace them or clean them off. (rub your finger over them to get the metal/plastic particles off)
Put pan back on, following pattern to torque bolts to proper specs.
Refill with however many qts it takes (I think a dry fill is 11Qts on a 4T80E, at least my filter kit says so)
see i dont want to mess with this and do it myselfThe filter is internal and only gets changed during a tear down. Screens are in the pan and get cleaned if needed when the pan is dropped. Dropping the pan will not drain what's in the torque converter. That can be done by pulling the line off of the radiator side tank and pumping it dry.
from http://www.cadillacforums.com/forum...9940-would-you-like-some-cheese-crackers.htmlOne month ago I brought my car into to the dealer for a tranny fluid change, and to get the two filter screens replaced. You know, just as a precautionary thing since I drive it pretty hard, and it had 89k miles on it. They ended up doing a fluid FLUSH, and told me they couldn't change the screens because they would have to drop the cradle or some crap. Now, it's one month and 2k miles later, and the tranny is whining like crazy at all speeds, and all temperarutes (i.e. warmed up or not). I looked it up in my service manual and it says that a possible cause might be one of the two pumps. I bet some crap got stirred up and is clogging some port, and is probably starving one or both of the pumps of fluid. This is just what I need. I'm taking it in tomorrow to get it looked at. Anyone have any suggestions as to what I might have to do to get this fixed? I'm not in the mood to pay for them to do the job right the second time around. It should have been done right the first time. Figures....nothing ever goes right for me at the dealer.:helpless:
I called the deaeler the other day and asked what the price of there Spring SpecialTake it to a GM dealer, not AAMCO, use their Spring Special transmission fluid change, don't try to tell them what to do, and you'll soon have a clean transmission correctly filled with the latest GM recommended fluid and a receipt that says the work was done and also someone to fall back on if you're not happy for some reason.
I would steer away from a flush, no matter where. Read the post I wrote above. That was a flush at a big name Cadillac dealership. A flush is a transfusion machine... the debris from the previous user has the potential of ending up in your tranny. Not saying it will, but "it could." It has happened before, and it will happen again.I called the deaeler the other day and asked what the price of there Spring Special
they said they have a tranmission flush for 129.99
oil change for 30 somthing
and full synthetic oil change for 82
they said there was nothing els
so are they just trying to screw me by not giving the GM deal
is there a code they would have ot put in to find this deal anyone know what it is i called all the deallers around me and no one has heard of this
