Its not really that hard. You just need to take your time and a very large pan. Your filter is just in side the trans pan. The pan will have to be dropped. A ratchet and socket will make short work of it. Just undo the bolts on the trans pan( undo 3 corners and the bolts on that side, allowing the pan to lean to drain some of the fluid). Hold pan steady, and undo remaining bolts. Lower the pan. Now its time to scrape the old gasket off the pan and trans case. Please clean to metal, don't want leaks. Remove the old filter, and replace with the new one. Install the gasket to the pan, and bolt the pan back into place. If you put 4 bolts from around the pan, makes it easier to put the rest in. Now to refill the trans, you need a funnel and add the fluid ant the dipstick. Bring it back up to level. This job will take a beginner about one hour. Hope this helps

Change fluid on 2005 GMC Jimmy and now revving

did you change the filter too? If so is the new filter EXACTLY like the old one? Are you sure the trans is full of fluid? Sounds like a wrong filter or low fluid. Also is there a dent in the trans pan that could be hindering the fluid flow into the filter? If this is the case replace the pan.

My 1998 gmc jimmy transmission is not shifting right. i just had the fluid changed it was black looking. after changing the fluid it shifted ok at first but now the fluid is starting to get dark looking...

I would try changing the fluid and filter again. Sounds to me like there is a lot of crud built up in it and another change would probably do the trick. It probably wouldn't hurt to add a bottle of Lucas Trans Fluid at the same time. It will help extend the life of your transmission. Black fluid would likely be clutch material that wears off over time.
If this doesn't work you are likely in the market for another trans. Hope this helps.

Can we flush the transmission fluid in her GMC 1998 Jimmy?

You dont have to flush the fluid because transmission fluid has detergents in it that will clean the transmission.You need to go ahead and by a transmission filter, its only abou 20 dollars and it will come with the transmission pan gasket. All you need is the filter and fluid and a catch pan and you can do it in your front yard if you want to. I hope that helps you out!

1999 gmc suburban rpms go up but car does,nt go any faster

Have you checked the transmission fluid level?  Also, have you changed the transmission filter?  I would definately do these two before I would take it to a shop.  A typical transmission filter/gasket kit costs about $10-15 for that truck.  And the transmission fluid will run around $2-4 per quart.
Changing the filter is easy.  You will just take the transmission pan off and then pull the filter out, replace the filter, and then replace the pan gasket.  Then bolt it all back up and fill it with fluid!  It's that simple.
