Hello,

I'm getting ready to change the rear main seal on my 04 Cav with 145,000mi on it. Its an auto. I'll be doing it in the next two weeks whenever I get about 6 solid hours. I own the haynes manual and am pretty mechanically inclined, but have never done one of these before and wanted to see if there are any tricks of the trade that anyone can loan me. I have access to a full auto shop, so my car will be on a frame lift and the engine will have the sling type temporary harness that fits over the fenders of the car. I'll also have an actual transmission jack to lower the tranny out of the car. Any pictures of you doing your seal or tips would be appreciated!


Also, is there any maintenance that is good to do while the tranny is out besides the rear main seal?

There is a good picture on the gm build book, you can find it online...
